“The Dwarf sees farther than the Giant, when he has the Giant's shoulders to mount on.”

The Anatomy of Melancholy (1621), Democritus Junior to the Reader

Metalogicon (1159) bk. 3, ch. 4. Translation from Henry Osborn Taylor The Mediaeval Mind ([1911] 1919) vol. 2, p. 159; such similes were available to Isaac Newton, when he humbly made use of them in comparing his progress in scientific ideas to those whose ideas he drew upon, in his famous statement to Robert Hooke in a letter of 15 February 1676: If I have seen further it is by standing on the shoulders of Giants.

As quoted by Craig R. Whitney in WAR IN THE GULF: EUROPE; Gulf Fighting Shatters Europeans' Fragile Unity, The New York Times, January 25th, 1991. http://www.nytimes.com/1991/01/25/world/war-in-the-gulf-europe-gulf-fighting-shatters-europeans-fragile-unity.html?pagewanted=1
This phrase was pronounced in January 1991, a few days before the beginning of Desert Storm, while Eyskens was the Foreign Minister of Belgium.

Letter to Robert Hooke (15 February 1676) [dated as 5 February 1675 using the Julian calendar with March 25th rather than January 1st as New Years Day, equivalent to 15 February 1676 by Gregorian reckonings.] A facsimile of the original is online at The digital Library https://digitallibrary.hsp.org/index.php/Detail/objects/9792. The quotation is 7-8 lines up from the bottom of the first page. 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 [the Moderns] are like dwarves perched on the shoulders of giants [the Ancients], and thus we are able to see more and farther than the latter. 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. Modernized variants: If I have seen further it is by standing on the shoulders of giants. If I have seen further it is only by standing on the shoulders of giants.
Variant: If I have seen further it is by standing on ye sholders of Giants.

This evokes the statement by Newton: "If I have seen further, it is by standing on the shoulders of giants."
