Of all whose words I have heard, no one attains to this, to know that wisdom is apart from all.
Men who are lovers of wisdom [i.e., philosophers] must be inquirers into many things.
A hidden connection is stronger than an obvious one.
Change alone is unchanging.
A dry soul is wisest and best.
There is a stability in the Universe because of the orderly and balanced process of change, the same measure coming out as going in, as if reality were a huge fire that inhaled and exhaled equal amounts.
