Let man consider who he is and what he should and must become… Man needs more than common intelligence to know who he is; only he who studies him properly and knows whence he comes and who he is will also give profound attention to the eternal. . . .
Everything that man accomplishes or does, that he teaches or want to learn , must have its right proportion; it must follow its own line and remain within its circle, to the end that a balance be preserved, that there be no crooked thing, that nothing exceed the the circle.
— Pico Della Mirandola
