Context: Fermat knew that under reflection light takes the path requiring least time and, convinced that nature does indeed act simply and economically, affirmed in letters of 1657 and 1662 his Principle of Least Time, which states that light always takes the path requiring least time. He had doubted the correctness of the law of refraction of light but when he found in 1661 that he could deduce it from his Principle, he not only resolved his doubts about the law but felt all the more certain that his Principle was correct.... Huygens, who had at first objected to Fermat's Principle, showed that it does hold for the propagation of light in media with variable indices of refraction. Even Newton's first law of motion, which states that the straight line or shortest distance is the natural motion of a body, showed nature's desire to economize. These examples suggested that there might be a more general principle. The search for such a principle was undertaken by Maupertuis.
On his friend, George Orwell, in The Sunday Times (1968-09-29); reprinted in The Evening Colonnade (New York, 1973)
So, the flowers of your field, in so far as I am gardener, shall come from my heart where they reside in much good will; and my eye and hand shall attend merely to the cultivating, the weeding, the fungous blight, the noxious insect of the air, and the harmful worm below.
And so shall your garden grow; from the rich soil of the humanities it will rise up and unfold in beauty in the pure air of the spirit.
So shall your thoughts take up the sap of strong and generous impulse, and grow and branch, and run and climb and spread, blooming and fruiting, each after its kind, each flowing toward the fulfillment of its normal and complete desire. Some will so grow as to hug the earth in modest beauty; others will rise, through sunshine and storm, through drought and winter's snows year after year, to tower in the sky; and the birds of the air will nest therein and bring forth their young.
Such is the garden of the heart: so oft neglected and despised when fallow.
Verily, there needs a gardener, and many gardens.
