It was Plato, according to Sosigenes, who set this as a problem for those concerned with these things, through what suppositions of uniform and ordered movements the appearances concerning the movements of the wandering heavenly bodies could be preserved.
In the world of knowledge, the essential Form of Good is the limit of our inquiries, and can barely be perceived; but, when perceived, we cannot help concluding that it is in every case the source of all that is bright and beautiful -in the visible world giving birth to light and its master, and in the intellectual world dispensing, immediately and with full authority, truth and reason -and that whosoever would act wisely, either in private or in public, must set this Form of Good before his eyes.

When a thought of Plato becomes a thought to me,--when a truth that fired the soul of Pindar fires mine, time is no more.
