Retrograde Quotes (8 quotes)

After I had addressed myself to this very difficult and almost insoluble problem, the suggestion at length came to me how it could be solved with fewer and much simpler constructions than were formerly used, if some assumptions (which are called axioms) were granted me. They follow in this order.
There is no one center of all the celestial circles or spheres.
The center of the earth is not the center of the universe, but only of gravity and of the lunar sphere.
All the spheres revolve about the sun as their mid-point, and therefore the sun is the center of the universe.
The ratio of the earth’s distance from the sun to the height of the firmament is so much smaller than the ratio of the earth’s radius to its distance from the sun that the distance from the earth to the sun is imperceptible in comparison with the height of the firmament.
Whatever motion appears in the firmament arises not from any motion of the firmament, but from the earth’s motion. The earth together with its circumjacent elements performs a complete rotation on its fixed poles in a daily motion, while the firmament and highest heaven abide unchanged.
What appears to us as motions of the sun arise not from its motion but from the motion of the earth and our sphere, with which we revolve about the sun like any other planet. The earth has, then, more than one motion.
The apparent retrograde and direct motion of the planets arises not from their motion but from the earth’s. The motion of the earth alone, therefore, suffices to explain so many apparent inequalities in the heavens.
'The Commentariolus', in Three Copernican Treatises (c.1510), trans. E. Rosen (1939), 58-9.

After innumerable dynasties of giant creatures, after endless generations of fish and families of molluscs, man finally arrives, the degenerate product of a grandiose type, his mould perhaps broken by his Creator. Fired by his retrospection, these timid humans, born but yesterday, can now leap across chaos, sing an endless hymn, and configure the history of the universe in a sort of retrograde Apocalypse.
From 'La Peau de Chagrin' (1831). As translated as by Helen Constantine The Wild Ass’s Skin (2012), 19.

I think that the use of tobacco is one of the most evident of all the retrograde influences of our time.

In the year 1456 ... a Comet was seen passing Retrograde between the Earth and the sun... Hence I dare venture to foretell, that it will return again in the year 1758.
A Synopsis of the Astronomy of Comets (1705),22.

Science, that gives man hope to live without lies
Or blast himself off the earth; curb science
Until morality catches up?
But look:
At present morality is running rapidly retrograde.
You’d have to turn science, too, back to the witch doctors,
the myth drunkards. Besides that,
Morality is not an end in itself; truth is an end.
To seek the truth is
better than good works, better than survival
Holier than innocence, and higher than love.
Poem, 'Curb Science?', in The Collected Poetry of Robinson Jeffers: 1938-1962 (1988), 199. The poem was suppressed until 1977.

The faculty of resolution is possibly much invigorated by mathematical study, and especially by that highest branch of it which, unjustly, merely on account of its retrograde operations, has been called, as if par excellence, analysis.
In The Murders in Rue Morgue.

The use of tobacco is one of the most evident of all the retrograde influences of our time. It invades all classes, destroys social life, and is turning, in the words of Mantegazza, the whole of Europe into a cigar divan.
Letter, 'Tobacco and the Diseases It Produces', The Times (25 Sep 1878), 4. Reprinted in Timaru Herald (29 Nov 1878), 29, No. 1309, 3.

When a Parliament, acting against the declared Sense of the Nation, would have appeared as surprising a phœnomenon in the moral World, as a retrograde Motion of the Sun, or any other signal Deviation of Things from their ordinary Course in the natural World.
In A Dissertation Upon Parties: In Several Letters to Caleb D’Anvers, Esq. (1733, 1735), 39.
Science quotes on:  |  Acting (6)  |  Against (332)  |  Appeared (4)  |  Course (413)  |  Declare (48)  |  Declared (24)  |  Deviation (21)  |  Moral (203)  |  Motion (320)  |  Nation (208)  |  Natural (810)  |  Ordinary (167)  |  Other (2233)  |  Parliament (8)  |  Phenomenon (334)  |  Sense (785)  |  Signal (29)  |  Sun (407)  |  Surprising (4)  |  Thing (1914)  |  World (1850)


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
