Newton's famous letter to Robert Hooke where he wrote his now famous sentence: "If I have seen further, it is by standing on the shoulders of giants." 📝 Cambridge, February 5, 1675 Dr. Sir, At the reading of your letter I was exceedingly pleased and satisfied with your generous freedom, and think you have done what becomes a true philosophical spirit. There is nothing which I desire to avoyde in matters of philosophy more than contention, nor any kind of contention more than one in print; and, therefore, I most gladly embrace your proposal of a private correspondence. What’s done before many witnesses is seldom without some further concerns than that for truth; but what passes between friends in private usually deserves the name of consultation rather than contention, and so I hope it will prove between you and me. Your animadversions will therefore be welcome to me; for though I was formerly tyred of this subject by the frequent interruptions it caused to me, and have not yet, nor I believe ever shall recover so much love for it as to delight in spending time about it; yet to have at once in short the strongest objections that may be made, I would really desire, and know no man better able to furnish me with them than yourself. In this you will oblige me, and if there be any thing else in my papers in which you apprehend I have assumed too much, if you please to reserve your sentiments of it for a private letter, I hope you will find that I am not so much in love with philosophical productions, but that I can make them yield. But, in the mean time, you defer too much to my ability in searching into this subject. What Descartes did was a good step. You have added much several ways, and especially in considering the colours of thin plates. If I have seen farther, it is by standing on the shoulders of giants. But I make no question you have divers very considerable experiments beside those you have published, and some, it’s very probable, the same with some of those in my late papers. Two at least there are, which I know you have often observed—the dilatation of the coloured rings by the obliquation of the eye, and the apparition of a black spot at the contact of two convex glasses, and at the top of a water-bubble; and it’s probable there may be more, besides others which I have not made, so that I have reason to defer as much or more in this respect to you, as you would to me. Your letter gives me occasion to enquire regarding an observation you was propounding to me to make here of the transit of a star near the zenith. I came out of London some days sooner than I told you of, it falling out so that I was to meet a friend then at Newmarket, and so missed of your intended directions; yet I called at your lodgings a day or two before I came away, but missed of you. If therefore you continue to have it observed, you may, by sending your directions, command your humble servant, Is. Newton
