Unalterability Quotes

Concepts that have proven useful in ordering thi ngs easily achieve such authority over us that we forget their earthly origins and accept them as unalterable givens.

Every science has for its basis a system of principles as fixed and unalterable as those by which the universe is regulated and governed. Man cannot make principles; he can only discover them.
In The Age of Reason (1794, 1834), 30-31.

For mathematics, in a wilderness of tragedy and change, is a creature of the mind, born to the cry of humanity in search of an invariant reality, immutable in substance, unalterable with time.
In The American Mathematical Monthly (1949), 56, 19. Excerpted in John Ewing (ed,), A Century of Mathematics: Through the Eyes of the Monthly (1996), 186.

The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amœbζ which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual develops from an egg, which, in common with those of all animals, is a simple cell, most clearly proves that the most remote ancestors of man were primordial animals of this sort, of a form equivalent to a simple cell. When, therefore, the theory of the animal descent of man is condemned as a “horrible, shocking, and immoral” doctrine, tho unalterable fact, which can be proved at any moment under the microscope, that the human egg is a simple cell, which is in no way different to those of other mammals, must equally be pronounced “horrible, shocking, and immoral.”
Translated from his Ueber die Entstehung und den Stammbaum des Menschengeschlechts, (1873), Vol. 2, as an epigraph to Chap. 6, The Evolution of Man, (1879), Vol 1, 120-121.

The mathematic, then, is an art. As such it has its styles and style periods. It is not, as the layman and the philosopher (who is in this matter a layman too) imagine, substantially unalterable, but subject like every art to unnoticed changes form epoch to epoch. The development of the great arts ought never to be treated without an (assuredly not unprofitable) side-glance at contemporary mathematics.
In Oswald Spengler and Charles Francis Atkinson (trans.), The Decline of the West (1926), 62.

…at the stars,
Which are the brain of heaven, he look’d, and sank.
Around the ancient track marched, rank on rank,
The army of unalterable law.
In poem, 'Lucifer in Starlight', collected in Arthur Quiller-Couch (ed.), The Oxford Book of English Verse: 1250–1900 (1919), 942.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
