It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent; because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses. Yet the thing is not altogether desperate; for we have some arguments to guide us, partly from the apparent motions, which are the differences of the true motions; partly from the forces, which are the causes and effects of the true motions.

But to return to Kepler, his great sagacity, and continual meditation on the planetary motions, suggested to him some views of the true principles from which these motions flow. In his preface to the commentaries concerning the planet Mars, he speaks of gravity as of a power that was mutual betwixt bodies, and tells us that the earth and moon tend towards each other, and would meet in a point so many times nearer to the earth than to the moon, as the earth is greater than the moon, if their motions did not hinder it. He adds that the tides arise from the gravity of the waters towards the moon. But not having just enough notions of the laws of motion, he does not seem to have been able to make the best use of these thoughts; nor does he appear to have adhered to them steadily, since in his epitome of astronomy, published eleven years after, he proposes a physical account of the planetary motions, derived from different principles.
Johannes Kepler
I am dominated by one thing, an irresistible, burning attraction towards the abstract. The expression of human feelings and the passions of man certainly interest me deeply, but I am less concerned with expressing the motions of the soul and mind than to render visible, so to speak, the inner flashes of intuition which have something divine in their apparent insignificance and reveal magic, even divine horizons, when they are transposed into the marvellous effects of pure plastic art.
Gustave Moreau
Guys I'm going to let you in on a secret. This is going to take a big weight off your shoulders, so I want you to may attention, cause here it comes... If you only have sex with your wife, you can't get caught. [Makes a gesture with his hands on his shoulders] You feel that, guys? Nobody gives a rat's ass. No guy is going to bust in the bedroom door, "White, you motherfu- Is that your wife you're screwing!" (Makes motions like he's having sex and turns and looks over his shoulder and says nothing just gives a look as if to say, "Smart ass!') Actually I may have exaggerated that stroke a little. (Makes motions again, but this time a lot faster.) Ferocious piece of ass. But easily winded.

I can calculate the motions of the heavenly bodies, but not the madness of people.
Isaac Newton
Mr. Darwin's hypothesis is not, so far as I am aware, inconsistent with any known biological fact; on the contrary, if admitted, the facts of Development, of Comparative Anatomy, of Geographical Distribution, and of Palaeontology, become connected together, and exhibit a meaning such as they never possessed before; and I, for one, am fully convinced that if not precisely true, that hypothesis is as near an approximation to the truth as, for example, the Copernican hypothesis was to the true theory of the planetary motions.
