Anaximander says that men were first produced in fishes, and when they were grown up and able to help themselves were thrown up, and so lived upon the land.
Anaximander used to assert that the primary cause of all things was the Infinite, not defining exactly whether he meant air or water or anything else.
Anaximander relies on the accuracy of geometry in matters beyond the range of any kind of verification in its application to cosmic proportions and also in contradiction to appearance, which suggests that the sun is about as large in diameter as the width of a human foot. The concept of geometrical similarity is also the precondition for Anaximander's attempt to construct a map of the world.
Anaximander the Milesian, affirmed the infinite to be the first principle, and that all things are generated out of it, and corrupted again into it. His infinite is nothing else but matter.
