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.
Socrates and Plato are right: whatever man does he always does well, that is, he does that which seems to him good (useful) according to the degree of his intellect, the particular standard of his reasonableness.
Ignorance of all things is an evil neither terrible nor excessive, nor yet the greatest of all; but great cleverness and much learning, if they be accompanied by a bad training, are a much greater misfortune.
It is in the stomach of plants that development begins, and ends in the circles of the universe.

The beginnings are slow and infirm, but it is an always accelerated march.
Too much attention to health is a hindrance to learning, to invention, and to studies of any kind, for we are always feeling suspicious shootings and swimmings in our heads, and we are prone to blame studies from them.
