To get everything you want is not a good thing. Disease makes health seem sweet. Hunger leads to the appreciation of being full-fed. Tiredness creates the enjoyment of resting

All entities move and nothing remains still.

Knowledge is not intelligence.

Most people do not take heed of the things they encounter, nor do they grasp them even when they have learned about them, although they suppose they do.

Those unmindful when they hear, for all they make of their intelligence, may be regarded as the walking dead.

A blow to the head will confuse a man's thinking, a blow to the foot has no such effect, this cannot be the result of an immaterial soul.

All things are in a state of flux.
