Prof. Barus' Retirement dinner speech, Brown University (1926) as quoted by in One of the 999 about to be Forgotten: Memoirs of Carl Barus, 1865-1935 (2005) ed., Axel W.-O. Scmidt.
Context: [L]et me refer to my original work. Naturally, if a student has been hammering away ever since 1979... he must have accumulated a lot of litter, much of which, perhaps, should have long since been swept away. But the fates are not to be bribed either by pother or importunity. Out of 1,000 men who are called, one (probably the ratio is much smaller) is chosen to do glorious scientific work. The others? Their lot is failure. They may be equally or even more industrious, they may have equal or even greater brain power—the other 999 exist merely to make the illustrious one in whom they culminate, possible. After that, the world will say to each in words of poetic brevity: "The man has done his duty, the man can go." And they do, pretty quickly, to a gentler lethe, flowing between the banks of amaranth and asphodel.
Gentlemen, I am one of the 999 about to be forgotten.

The Temper of Our Time (1967)
Context: The ratio between supervisory and producing personnel is always highest where the intellectuals are in power. In a Communist country it takes half the population to supervise the other half.

The Kasîdah of Hâjî Abdû El-Yezdî (1870), Note I : Hâjî Abdû, The Man
Context: He looks with impartial eye upon the endless variety of systems, maintained with equal confidence and self-sufficiency, by men of equal ability and honesty. He is weary of wandering over the world, and of finding every petty race wedded to its own opinions; claiming the monopoly of Truth; holding all others to be in error, and raising disputes whose violence, acerbity and virulence are in inverse ratio to the importance of the disputed matter. A peculiarly active and acute observation taught him that many of these jarring families, especially those of the same blood, are par in the intellectual processes of perception and reflection; that in the business of the visible working world they are confessedly by no means superior to one another; whereas in abstruse matters of mere Faith, not admitting direct and sensual evidence, one in a hundred will claim to be right, and immodestly charge the other ninety-nine with being wrong.
Thus he seeks to discover a system which will prove them all right, and all wrong; which will reconcile their differences; will unite past creeds; will account for the present, and will anticipate the future with a continuous and uninterrupted development; this, too, by a process, not negative and distinctive, but, on the contrary, intensely positive and constructive. I am not called upon to sit in the seat of judgment; but I may say that it would be singular if the attempt succeeded. Such a system would be all-comprehensive, because not limited by space, time, or race; its principle would be extensive as Matter itself, and, consequently, eternal. Meanwhile he satisfies himself, — the main point.

Last paragraph of the first edition (1859). Only use of the term "evolve" or "evolution" in the first edition.
In the second http://darwin-online.org.uk/content/frameset?pageseq=508&itemID=F376&viewtype=image (1860) through sixth (1872) editions, Darwin added the phrase "by the Creator" to read:
There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.
