  My dear James,

  I'm sorry to have lost touch with you over the past few years; we
  haven't seen each other since the French War, back in 1948. Nine years!
  It doesn't seem it.

  I'll tell you right off I want a favour of you. (No, I do _not_
  want to borrow another five shillings! I haven't had my pocket picked
  again, thank you.) This has to do with a little historical research I'm
  doing here. I stumbled across something rather queer, and I'm hoping
  you can help me with it.

  I am enclosing copies of some old letters received by Isaac Newton
  nearly three hundred years ago. As you will notice, they are addressed
  to "Mr. Isaac Newton, A.B."; it rings oddly on the ear to hear the
  great man addressed as anything but "your Grace," but of course
  he was only a young man at the time. He hadn't written his famous
  _Principia_ yet--and wouldn't for twenty years.

  Reading these letters is somewhat like listening to a conversation when
  only one of the speakers is audible, but they seem to indicate another
  side to the man, one which has not heretofore been brought to light.

  Dr. Henry Blake, the mathematician, has looked them over, and he feels
  that it is possible that Newton stumbled on something that modern
  thought has only recently come up with--the gravitational and light
  theories of the Swiss mathematician, Albert Einstein.

  I know it's fantastic to think that a man of even Newton's acknowledged
  genius could have conceived of such things three centuries before
  their proper place in history, but Blake says it's possible. And if
  it is, Blake himself will probably do to Newton's correspondents the
  same thing that was done to Oliver Cromwell at the beginning of the
  Restoration--disinter the bodies and have them publicly hanged or some
  such thing.

  Actually, Blake has managed to infect me with his excitement; he has
  pointed out phrases in several of the letters which tally very well
  with Einstein's theory. But, alas, the information we have is woefully
  incomplete.

  What we need, you see, are Newton's letters--the ones he sent which
  provoked these answers. We have searched through everything here
  at Cambridge, and we haven't found even a trace; evidently the
  Newton manuscripts were simply discarded on the basis that they were
  worthless, anyway. Besides, records of that sort were poorly kept at
  that time.

  But we thought perhaps the War Office did a somewhat better job of
  record-keeping.

  Now, I realise full well that, due to the present trouble with the
  Austro-Hungarian Empire, the War Office can't take a chance and allow
  just anyone to prowl through their files.

  It wouldn't do to allow one of the Emperor's spies to have a look
  at them. However, I wondered if it wouldn't be possible for you to
  use your connexions and influence at the War Office to look for
  Newton's letters to one of the correspondents, General Sir Edward
  Ballister-ffoulkes. You can find the approximate dates by checking the
  datelines on the copies I am sending you.

  The manuscripts are arranged in chronological order, just as they were
  received by Newton himself. Of them all, only the last one, as you will
  see, is perfectly clear and understandable in all its implications.

  Let me know what can be done, will you, old friend?

                                                    With best wishes,
                                                                  SAM

  Mr. Isaac Newton, A.B.
  Woolsthorpe

  Dear Mr. Newton:

  It was very good of you to offer your services to His Majesty's
  Government at this time. The situation on the Continent, while not
  dangerous in the extreme, is certainly capable of becoming so.

  Your letter was naturally referred to me, since no one else at the War
  Office would have any need for the services of a trained mathematician.

  According to your précis, you have done most of your work in geometry
  and algebra. I feel that these fields may be precisely what are needed
  in our programme, and, although you have had no experience, your record
  at Trinity College is certainly good enough to warrant our using your
  services.

  If you will fill in the enclosed application blank, along with the
  proper recommendations and endorsements, we can put you to work
  immediately.

                                                           Sincerely,
                                     Edward Ballister-ffoulkes, Bart.

  Mr. Isaac Newton, A.B.
  Woolsthorpe

  My dear Isaac,

  I am sorry to hear of your decision to remain at home for a while
  longer instead of returning to the College, but if you feel that your
  health is delicate, by all means rest until you are in better spirits.

  I think, however, that you should attempt to return as soon as
  possible; you have a great deal of work ahead of you, my boy.
  Mathematicians--like Rome--are not built in a day--nor in four years.

  If, however, you would like to do a part of your studies by post, I see
  no objection to it, under the circumstances, although, of course, it
  will be necessary to spend a part of your time in residence here, and
  the final examinations will have to be taken here.

  Later on, when you are feeling better, I will send an outline of some
  work I intend to do on conic sections; I think it would be of great
  benefit to you to work with me on this. I have always had confidence in
  your ability. You are young yet, but, given time and plenty of study,
  you should make a place for yourself in the world of mathematics.

  I think that the work I have in mind for you should prove stimulating.

                                                      Most sincerely,
                                                  Isaac Barrow, Ph.D.

  Dear Mr. Newton:

  It would most certainly be quite convenient for you to do your work
  there at Woolsthorpe.

  An explanation of the work we are trying to do and some of the problems
  we are up against will be despatched to you as soon as possible.

                                                           Sincerely,

  My dear Isaac,

  Your paper has arrived. I haven't had time to look it over yet, but I
  shall find time to peruse it during the forthcoming holidays. I am,
  of course, very interested in what problems concerned you during the
  summer.

  A very merry Christmas to you, my boy.

  FROM: Ballistics Research Dept.,
        British Army Artillery

  TO:   Isaac Newton, A.B.,
        Woolsthorpe

  SUBJECT: Ballistics research data.

  ENCLOSURE: Range table sample for 9-lb. artillery.

  2nd ENCLOSURE: Outline and general discussion of ballistics

  1. In order to better understand the problems facing this Department,
  you will familiarise yourself with the enclosed material.

  2. This material is confidential, and is not to be allowed to fall into
  unauthorised hands.

                                   By order of the Commanding General

                         SECOND ENCLOSURE

  The purpose of this project is to determine, with as great a degree of
  precision as possible, the range of artillery used by His Majesty's
  Armed Forces, and the methods of accurately firing upon targets at
  various distances from the cannon.

  After a great deal of research, the following factors have been found
  to affect the distance which a cannon ball may be hurled by exploding
  gunpowder:

  1. Weight of the cannon ball.

  2. Weight of powder used.

  3. Angle of elevation of cannon.

  4. Length of cannon barrel.

  The first two factors are obvious; the heavier the cannon ball,
  the more powder it will take to blow it a certain distance, and
  contrariwise.

  The third is somewhat unwieldy to work with and definitely
  problematical in its effects. Up to a certain point, increasing the
  angle seems to increase the range, but after that point is reached, an
  increase in elevation decreases the range of the weapon. In view of
  this, it has been decided that all cannon will be fixed at the best
  angle for maximum range and the other factors varied to change the
  actual distance the cannon ball is fired.

  (Here it may be noted, incidentally, that the angle of elevation is of
  no use in the Royal Navy, since that angle is indeterminate, due to the
  roll of the ship.)

  The fourth factor, too, may be discarded, since a barrel of too great
  a length would make it unwieldy on the battlefield, although those of
  fixed fortresses could be somewhat greater. And, in view of the fact
  that changing the length of a cannon barrel on the field is out of the
  question, we may safely say that the fourth factor is a fixed quantity
  in each cannon and thus ignore it.

  It has, therefore, been decided to test each of the various types of
  cannon presently in use by Army Artillery and publish for each a range
  table for various cannon balls and charges of powder, and to furnish a
  copy of such table to the battery leader of each field piece.

  This programme, as may well be imagined, has required a great deal
  of cannon testing in the past year, and will undoubtedly require a
  great deal more before the project is finished. We hope, however, that
  it will be of at least limited use in the very near future, and will
  eventually greatly advance the science of cannon-firing.

  My dear Isaac,

  Your Christmas was, I trust, a pleasant one? I hope your mother is in
  good health, and I hope your own is improved.

  My dear boy, I have some advice for you; I do hope that you will take
  it as it is intended--as from an old friend and tutor who wishes you
  only well.

  It has come to my attention that you are--shall we say--prostituting
  your talents. A friend of mine who works at the War Office tells me
  that you are doing some mathematical work by correspondence--something
  to do with cannon, I believe.

  Now, I quite understand that you are in a somewhat precarious financial
  position, and believe me, I deeply sympathise with you. I know that the
  earning of a few pounds can mean a great deal to you in furthering your
  education.

  I do not say that such work is menial, either. I would not have you
  think that I deplore your choice of work in any way; it is necessary
  work, and money is certainly necessary for life.

  However, let me warn you: a simple task like this, which pays rather
  well, can become soporific in its effect. Many men of talent, finding
  themselves comfortably fixed in a mediocre position, have found their
  minds have become stultified through long disuse. _Please_, dear
  boy, don't fall into that trap; don't throw away a fine career in
  mathematics for the sake of a few paltry pounds. You are young and
  inexperienced, I know, and have a great deal yet to learn, so please
  take the advice of one who is somewhat older and wiser.

  No, I haven't gotten round to reading your paper yet; I'll do it this
  evening, my boy, I promise.

                                                      Most sincerely,
                                                         Isaac Barrow

                                                            Cambridge

  My dear Isaac,

  I read your paper, and I am, I must confess, somewhat nonplussed. What
  _are_ you doing?

  I see that my letter of yesterday was somewhat premature; I should have
  waited until I had read your paper, since it is in exactly the same
  category.

  You ask: "What is the optimum shape for a wine barrel? Should it be
  tall and thin, or squat and broad?"

  And I ask: "What on Earth difference does it make?"

  Surely you are not thinking of becoming a wine merchant? If so, what
  need is there to waste your time studying mathematics? On the other
  hand, if you intend to become a mathematician, why should you debase a
  noble and lofty study by applying it to wine barrels?

  As I told you, I have no objection to your making a few pounds by doing
  minor calculations for the Army, but this is foolishness. You have gone
  to a great deal of trouble for nothing; as you gain more experience,
  you will realize the folly of such things.

  As to your theory of "fluxions," I admit myself to be completely at a
  loss. You seem to be assuming that a curve is made up of an infinite
  number of infinitely small lines. Where is your authority for such a
  statement? You append no bibliography and no references, and I cannot
  find it in the literature.

  Apparently, you are attempting to handle _zero_ and
  _infinity_ as though they were arithmetical entities. Where did
  you learn such nonsense?

  My boy, please keep it in mind that four years of undergraduate work
  does not qualify one as a mathematician. It is merely the first
  stepping stone on the way. You have a great deal of studying yet to do,
  a great many books yet to read and absorb--books, I may say, written by
  men older, wiser, and more learned than yourself.

  Please don't waste your time with such frivolous nonsense as toying
  with symbols derived from wine barrels. No good can come out of a wine
  barrel, my boy.

  I hope you will soon find yourself in a position to aid me in some of
  the calculations on conic sections as I outlined them to you in my
  letter of the 28th December last.[1] I feel that this is important
  work and will do a great deal to further your career.

                                                With all best wishes,
                                                           Sincerely,
                                                         Isaac Barrow

  Dear Mr. Newton:

  Thank you for your tabulations on the seven-pounder. I must say you
  were very prompt in your work; there was no need to work over the
  holidays.

  Your questions show that you are unacquainted with the difficulties of
  manufacturing military arms; I am not at all surprised at this, because
  it takes years of training and practical experience in order to learn
  how to handle the various problems that come up. It is something that
  no university or college can teach, nor can it be learned from books;
  only experience in the field can teach it, and you have had none of
  that.

  I can, however, explain our method of approach thus:

  Each cannon to be tested is fired with several balls--some of iron,
  some of lead, some of brass, and some which have been hollowed out to
  make room for a charge of gunpowder in order that they may explode
  upon reaching the target. With each type of ball, we find the amount
  of powder required to drive the ball five yards from the muzzle of
  the piece; this is considered the minimum range. (Naturally, with
  the testing of hollow, explosive missiles, we do not fill them with
  gunpowder, but with common earth of equal weight. To do otherwise would
  endanger the cannoneer.)

  After the minimum range is found, more balls are fired, using greater
  amounts of powder, added in carefully measured increments, and the
  distance achieved is measured off.

  This process is kept up until the safety limit of the weapon is
  reached; this point is considered the maximum range.

  Naturally, the weights of different balls will vary, even if they
  are made of the same metal, and the bores of cannon will vary, too,
  but that can't be helped. What would you have us do? Make all cannon
  identical to the nearest quarter-inch? It would not be at all practical.

  I am happy to see that you are enthusiastic over the work we are
  doing, but please, I beg you, wait until you have learned a great deal
  more about the problem than you have done before you attempt to make
  suggestions of such a nature.

  As to the paper which you enclosed with your tabulations, I am afraid
  that it was of little interest to me. I am a military man, not a
  mathematician.

  Thanking you again for your excellent work, I remain.

                                                     Yours sincerely,
                                     Edward Ballister-ffoulkes, Bart.

  My dear Isaac,

  I have known you for more than five years, and I have, I might say, a
  more than parental interest in you and your career. Therefore, I feel
  it my duty to point out to you once again that your erratic temper will
  one day do you great harm unless you learn to curb it.

  You take me to task for saying to you what is most certainly true,
  viz.: that you are not yet a mathematician in the full sense of the
  word. You are young yet. When you have put in as many years at study as
  I have, you will understand how little you now know. Youth is inclined
  to be impetuous, to rush in, as the saying goes, where angels fear
  to tread. But better men than yourself have come to realise that the
  brashness of youth is no substitute for the wisdom of maturity.

  As to your other remarks, you know perfectly well what I meant when
  I said that no good can come out of a wine barrel. To accuse me of
  sacrilege and blasphemy is ridiculous. You are twisting my words.

  Please let us have no more of this name-calling, and get down to more
  important work.

                                                           Sincerely,
                                                         Isaac Barrow

  Dear Mr. Newton:

  Thank you again for your rapid work in tabulating our results. It is
  most gratifying to find a young man with such zeal for his work.

  As I have said before, I am no mathematician, but I must confess that
  your explanation makes very little more sense to me than your original
  mathematical formulae.

  As I understand it, you are proposing a set of equations which will
  show the range of any weapon by computing the weight of the ball
  against the weight of the powder. (Perhaps I err here, but that is my
  understanding.) It seems to me that you are building a castle-in-Spain
  on rather insubstantial ground. Where is your data? What research have
  you done on cannon-fire? Without a considerable body of facts to work
  with, such broad generalisations as you propose are quite out of order.

  Even if such a thing could be done--which, pardon me, I take the
  liberty to doubt--I fear it would be impractical. I realise that you
  know nothing of military problems, so I must point out to you that our
  cannoneers are enlisted men--untutored, rough soldiers, not educated
  gentlemen. Many of them cannot read, much less compute abstruse
  geometrical formulae. It will be difficult enough to teach them to use
  the range tables when we complete them.

  Indeed, I may say that this last point is one of the many
  stumbling-blocks in the path of our project. More than one of the staff
  at the War Office has considered it to be insurmountable, and many
  times I have fought for the continuance of the research in the face of
  great opposition.

  I greatly fear that using any but methods known to be practicable would
  result in our appropriation being cut off in Parliament.

  Again, however, I thank you for your interest.

                                                      Most sincerely,
                                                   Ballister-ffoulkes

  My dear Isaac,

  I am truly sorry I didn't get around to looking over your second
  manuscript until now, but, to be perfectly truthful, I have been
  outlining our course of work on conic sections, and had little time for
  it.

  As it turns out, it was all for the best that I did so; it would
  have been sinful to take valuable time away from my work for such
  trivialities.

  You are still harping on your wine-barrel fluxions and your Army cannon
  balls. Am I to presume that the whole thing is a joke? Or are you
  seriously proposing that the path of a cannon ball is related to the
  phases of the moon? That is rank superstition! Sheer magic! One would
  think that even a lad as young as yourself would have grasped the basic
  concept of the Scientific Method by this time.

  How have you tested this absurd thing experimentally? Where are your
  measurements, your data? Your references?

  Do not think, my boy, that fame and fortune in the sciences can be
  achieved by pulling wild hypotheses out of your imagination. There is
  no short-cut to mastery of a difficult subject like mathematics; it
  requires years of hard work and study.

  As an example of what can happen when one has not learned enough of
  the subject, look at your own work. You appear to be handling Time
  as though it were a spatial dimension. You even end up, in several
  equations, with square seconds! Now, a yardstick will show that a
  foot up-and-down is the same as a foot East-and-West or a foot
  North-and-South. But where can you find a foot of time?

  Please, dear boy, use your time to study the things you have yet to
  learn; don't waste it exploring a nonsensical cul-de-sac.

  I will send you the outline on conic sections within the week.

                                                           Sincerely,
                                                         Isaac Barrow

  Dear Mr. Newton:

  In reference to your letter of 14 January 1667, on the simplified
  algebraic formulae for the prediction of the paths of cannon balls,
  our staff has considered the matter and found that not only is your
  mathematics incomprehensibly confusing, but the results are highly
  inaccurate. Where, may I ask, did you get such data as that? On what
  experimental evidence do you base your deductions? The actual data we
  have on hand are not at all in agreement with your computations.

  Men with more experience than yours, sir, have been working on this
  problem for several years, and nothing in our results suggests anything
  like what you put forth. Finding data is a matter of hard work and
  observation, not of sitting back in one's armchair and letting one's
  mind wander.

  It would, indeed, be gratifying if our cannon would shoot as far as
  your equations say they should--but they do not. I am afraid we shall
  have to depend on our test results rather than on your theories. It is
  fact--not fancy--which is required in dealing with military operations.

                                                           Sincerely,
                                     Edward Ballister-ffoulkes, Bart.

                                                      3 February 1667
                                                            Cambridge

  My dear Isaac:

  I feel it would clear the air all round if we came to an understanding
  on this thing. Your continued insistence that I pay attention to
  theories which have no corroboration in the literature and are based
  on, to say the least, insufficient confirmatory data, is becoming
  tedious. Permit me, as a friend, to show you where, in your youthful
  impetuosity, you err.

  In the first place, your contention that there is a similarity
  between the path of a cannon ball and the motion of the moon is
  patently ridiculous. I cannot imagine where you obtained such
  erroneous information. A cannon ball, when fired, strikes the earth
  within seconds; the moon, as anyone knows, has been in the sky
  since--according to Bishop Ussher--4004 B.C. Your contention that it
  remains held up by a force which pulls it down is verbal nonsense. Such
  a statement is semantically nothing but pure noise.

  You state that the path followed by a cannon ball is parabolic in
  nature. How do you know? Can you honestly say that you have measured
  the path of a cannon ball? Have you traced its path, measured it, and
  analysed it mathematically? Can you prove analytically that it is not
  an hyperbola or part of an ellipse? Have you any data whatsoever to
  back up your statements, or any authority to which you can refer?

  You make broad generalisations on the assumption that "every body
  is attracted equally to every other body"; that the earth attracts
  the moon in the same way that it attracts an apple or a cannon ball.
  Where is your data? You have not, I dare say, measured the attraction
  between every body in the universe. Have you checked the variations in
  apples according to sugar content or the variations in cannon balls
  with reference to their diameters? If not, have you checked with any
  reliable authority to see if such work has already been done?

  And where did you learn that anyone can just sit down and make up
  one's own mathematical systems? I am certain that I taught you no such
  thing. Mathematics, my boy, is based on logical interpretation of
  known facts. One cannot just go off half-cocked and make up one's own
  system. What would happen to mathematics as a science if anyone should
  just arbitrarily decide that two added to two yields five or that two
  multiplied by two equals one hundred?

  You said that the whole thing came to you "in a flash" last summer when
  you were sitting under an apple tree and one of the fruit fell and
  struck you on the head. I suggest that you see a good physician; blows
  on the head often have queer effects.

  If you have the data to prove your contentions, and can show how your
  postulates were logically deduced, then I will be very happy to discuss
  the problem with you.

  As soon as you feel better, and are in a more reasonable frame of mind,
  I hope you will return to Cambridge and continue with the studies which
  you so badly need.

                                                           Sincerely,
                                                     Dr. Isaac Barrow

  P.S.: It occurs to me that you may have meant your whole scheme as
  some sort of straight-faced pseudo-scientific joke, similar to that of
  another gentleman who bears our common Christian name.[2] If so, I fail
  to comprehend it, but if you would be so kind as to explain it to me, I
  will be only too happy to apologise for anything I have said.

                                                           Is. Barrow

  obscure as the joke.--S.H.]

  Dear Mr. Newton:

  I have tried to be patient with you, but your last letter was
  sulphurous beyond all reason. I may not, as you intimate, be qualified
  to judge the mathematical worth of your theories, but I can and do feel
  qualified to judge their practical worth.

  For instance, you claim that the reason your computations did not tally
  with the data obtained from actual tests was that the cannon ball was
  flying through the air instead of a vacuum. By whose authority do you
  claim it would act thus-and-so in a vacuum? Do you have any data to
  substantiate your claim? Have you ever fired a cannon in a vacuum? For
  that matter have you ever fired a cannon?

  What would you have our cannoneers do--use a giant-sized Von Guericke
  Air Pump to evacuate the space between the cannon and the target? I
  fear this would be, to say the very least, somewhat impractical and
  even dangerous under battle conditions. I presume a tube of some
  kind would have to be built between the enemy target and the gun
  emplacement, and I dare say that by that time the enemy would become
  suspicious and move the target.

  You speak of "ideal conditions." My dear Newton, kindly keep it in mind
  that battles are never fought under ideal conditions; if they were, we
  should always win them.

  If you wish to spend your time playing with airy-fairy mathematical
  abstrusities which have no basis in fact, that is perfectly all right
  with me. This is a free country, and no one proposes to dictate one's
  private life. However, I would appreciate it if you would do me the
  honor of not burdening my already overtaxed mind with such patent
  nonsense.

  Otherwise, your work with the tabulations has been most excellent; I am
  enclosing a cheque for £20 to cover your work so far.

                                                           Sincerely,
                                     Edward Ballister-ffoulkes, Bart.

  My dear Newton:

  You have stretched the bonds of friendship too far. You have presumed
  upon me as a friend, and have quite evidently forgotten my position as
  head of the Department of Mathematics at this College.

  The harsh language in which you have presumed to address me is too
  shocking for any self-respecting man to bear, and I, for one, refuse
  to accept such language from my social inferiors. As a Professor of
  Mathematics in one of the most ancient of universities, I will not
  allow myself or my position to be ridiculed by a young jackanapes who
  has no respect for those in authority or for his elders.

  Your childish twaddle about glass prisms producing rainbows--a fact
  which any schoolboy knows--is bad enough; but to say that I am such
  a fool that I would refuse to recognise "one of the most important
  advances in mathematics" is beyond the pale of social intercourse.

  Repeatedly during the last few months, you have attempted to foist
  off on me and others implausible and unscientific theories which have
  no basis whatever in fact and which no reputable scientist would be
  foolish enough to endorse. You are not a mathematician, sir; you are a
  charlatan and a mountebank!

  You have no data; you admit working from "intuition" and hypotheses
  cut out of whole cloth; you cannot and will not give any reliable
  authority for any of your statements, nor will you accept the reliable
  statements of better men than yourself.

  This unseemly behaviour forces me to exercise my prerogative and
  my authority in defence of the college and the university. I shall
  recommend to the authorities that you be refused readmission.

  1. In view of the increased personality friction between yourself and
  certain members of this department, this department feels that it would
  be to our mutual disadvantage to continue retaining your services as
  mathematical consultant.

  2. As of 16 February 1667 your employment is hereby terminated.

  date.

  My dear fellow,

  I am making this communication quite informal because of your equally
  informal method of--shall we say--getting my ear.

  I have been nagged at day and night for the past three weeks by a
  certain lady of our mutual acquaintance; she wants me to "do something
  for that nice young Mr. Newton." She seems to think you are a man of
  some intelligence, so, more in order to stop her nagging tongue than
  anything else, I have personally investigated the circumstances of your
  set-to with the Ballistics Research Department.

  I have spoken with General B-f, and looked over all the correspondence.
  Can't make head or tail of what you're talking about, myself, but
  that's beside the point. I did notice that your language toward the
  general became somewhat acid toward the last. Can't actually say I
  blame you; the military mind can get a bit stiff at times.

  And I'm afraid it's for that very reason that my hands are tied. You
  can't expect a man to run a kingdom if he doesn't back up his general
  officers, now, can you? Political history and the history of my own
  family show that the monarch is much better off if the Army and Navy
  are behind him.

  So I'm afraid that, our little lady notwithstanding, I must refuse to
  interfere in this matter.

                                                            Cambridge

  My dear Isaac,

  Please accept the humble apologies of an old friend; I have erred, and
  I beg you, in your Christian charity, to forgive me. I did not realise
  at the time I wrote my last letter that you were ill and overwrought,
  and I have not written since then because of your condition.

  As a matter of fact, when your dear mother wrote and told me of your
  unbalanced state of mind, I wanted desperately to say something to you,
  but the blessed woman assured me that you were in no condition for
  communication.

  Believe me, my dear boy, had I had any inkling at all of how ill you
  really were, I should have shown greater forbearance than to address
  you in such an uncharitable manner. Forgive me for an ungoverned tongue
  and a hasty pen.

  I see now that the error was mine, and it has preyed on my mind for
  these many weeks. I should have recognised instantly that your letters
  to me were the work of a feverish mind and a disordered imagination. I
  shall never forgive myself for not understanding it at the time.

  As to your returning to the College for further study, please rest
  assured that you are most certainly welcome to return. I have spoken
  to the proper authorities, and, after an explanation of the nature
  of your illness, all barriers to your re-entrance have been dropped.
  Let me assure you that they are well aware of what such an unhappy
  affliction can do to unsettle a man temporarily, and they understand
  and sympathise.

  I can well understand your decision not to continue your studies in
  mathematics; I feel that overwork in attempting something that was a
  bit beyond one of your tender years was as much responsible for your
  condition as that blow on the head from that apple. It is probably that
  which accounts for the fact that serious symptoms did not appear until
  late in March.

  I feel that you will do well in whatever new field you may choose, but
  please do not work so hard at it.

  Again, my apologies,

                                                         Isaac Barrow

                                                                 York

  To His Grace,
  The Most Reverend Dr. Isaac Newton,
  By Divine Providence the Lord Archbishop of Canterbury

  My Lord Archbishop,

  May I take this opportunity to give you my earnest and heartfelt thanks
  for the copy of your great work which you so graciously sent; I shall
  treasure it always.

  May I say, your Grace, that, once I had begun the book, I found it
  almost impossible to lay it down again. In truth, I could not rest
  until I had completed it, and now I feel that I shall have to read it
  again and again.

  In my humble opinion, your Grace is the greatest theological logician
  since the Angelic Doctor, St. Thomas Aquinas. And as for beauty and
  lucidity of writing, it ranks easily with "_De Civitate Deo_"
  of St. Augustine of Hippo, and "_De Imitatione Christi_" of St.
  Thomas à Kempis.

  I was most especially impressed by your reasoning on the mystical
  levitation of the soul, in which you show clearly that the closer a
  human soul approaches the perfection of God, the greater the attraction
  between that soul and the Spirit of God.

  Surely it must be clear to anyone that the more saintly a man becomes,
  the greater his love for God, and the greater God's love for His
  servant; and yet, you have put it so clearly and concisely, with such
  beautifully worded theological reasoning, that it becomes infinitely
  more clear. It is almost as though one could, in some mystical way,
  measure the distance between an individual soul and the Holy Presence
  of God by the measure of the mutual love and attraction between that
  soul and the Blessed Trinity.

  Your masterful analysis of the relative worthiness of those who
  have come to the Kingdom of Heaven on the Day of Judgment is almost
  awe-inspiring in its beauty. Even those souls which have been cleansed
  as white as snow by the forgiving Grace of God differ, one from
  another, and your comparison between those souls and a ray of pure
  white light striking a prism of clearest crystal is magnificent.

  The Church has always held that those whose entire lives have been
  lived in holy purity and in the Grace of God would hold a higher place
  in Heaven than those whose lives have been sinful, even though God, in
  His graciousness, has forgiven them their sins. But no one had shown
  how this might be so. Your analogy, showing how the white light of the
  sun may be graded into the colours of the rainbow, ranging from red
  to violet, illustrates wonderfully how Our Lord will grade His chosen
  servants on the Last Day, when the sinful souls of the damned are cast
  into Darkness.

  There are other instances, almost too numerous to mention, which
  show your immense theological understanding and deep thought. So
  thought-provoking are they that I would not dare to comment on them
  until I have re-read and studied them carefully, for fear I should show
  my own shallowness of mind.

  It is my belief that your "_Principia Theologica_" will be read,
  honored, and loved by Christians for many centuries to come.

  I shall, of course, write to you further and at greater length on this
  monumental work.

  Praying for God's blessing on you and your work, and for the fullness
  of God's grace during the coming Eastertide,

                                                                I am,
                                               Most faithfully yours,
                                                     William Sancroft
                                                 By Divine Permission
                                              Lord Archbishop of York


                              THE END
