Ptolemy Quotes

I know that I am mortal and the creature of a day; but when I search out the massed wheeling circles of the stars, my feet no longer touch the earth, but, side by side with Zeus himself, I take my fill of ambrosia, the food of the gods.

From all this we concluded that the first two divisions of theoretical philosophy should
rather be called guesswork than knowledge, theology because of its completely invisible
and ungraspable nature, physics because of the unstable and unclear nature of the matter;
hence there is no hope that philosophers will ever be agreed about them; and that only

And if it had some one common movement, the same as that of the other weights, it would clearly leave them all behind because of its much greater magnitude. And the animals and other weights would be left hanging in the air, and the earth would very quickly fallout of the heavens. Merely to conceive such things makes them appear ridiculous.
