![]() Letter to Robert Hooke (15 February 1676).I have not been able to discover the cause of those properties of gravity from phenomena, and I frame no hypotheses for whatever is not deduced from the phenomena is to be called a hypothesis, and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy.If I have seen further it is only by standing on the shoulders of giants. Modernized variants: If I have seen further it is by standing on the shoulders of giants.And this is not at all because of the acuteness of our sight or the stature of our body, but because we are carried aloft and elevated by the magnitude of the giants. The phrase is most famous as an expression of Newton's but he was using a metaphor which in its earliest known form was attributed to Bernard of Chartres by John of Salisbury: Bernard of Chartres used to say that we are like dwarves perched on the shoulders of giants, and thus we are able to see more and farther than the latter. The quotation is 7-8 lines up from the bottom of the first page.

The best and safest method of philosophizing seems to be, first to enquire diligently into the properties of things, and to establish these properties by experiment, and then to proceed more slowly to hypothesis for the explanation of them.Bacon was perhaps paraphrasing a statement in the Nicomachean Ethics: Where both are friends, it is right to prefer truth. This is a variation on a much older adage, which Roger Bacon attributed to Aristotle: Amicus Plato sed magis amica veritas.Plato is my friend - Aristotle is my friend - truth is a greater friend. Variant translations: Plato is my friend, Aristotle is my friend, but my best friend is truth.These are notes in Latin that Newton wrote to himself that he titled: Quaestiones Quaedam Philosophicae (c.Plato is my friend - Aristotle is my friend - but my greatest friend is truth.Amicus Plato - amicus Aristoteles - magis amica veritas.Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things. I have studied these things - you have not. I keep the subject constantly before me, and wait 'till the first dawnings open slowly, by little and little, into a full and clear light. To explain all nature is too difficult a task for any one man or even for any one age. Christ comes as a thief in the night, & it is not for us to know the times & seasons which God hath put into his own breast. If I have seen further it is by standing on ye sholders of Giants. Quotes Plato is my friend - Aristotle is my friend - but my greatest friend is truth. 1.6 Observations upon the Prophecies of Daniel, and the Apocalypse of St.1.3 "Hypothesis explaining the Properties of Light" (1675).1.1 Philosophiæ Naturalis Principia Mathematica (1687).Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus. His book Philosophiæ Naturalis Principia Mathematica ( Mathematical Principles of Natural Philosophy), first published in 1687, established classical mechanics. He was a key figure in the philosophical revolution known as the Enlightenment. Sir Isaac Newton ( Janu– Maor in Old Style: Decem– March 20, 1727) was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a " natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
