Plato

You cannot conceive the many without the one.

When the mind is thinking, it is talking to itself.

To understand is to perceive patterns.

Wealth is the parent of luxury and indolence, and poverty of meanness and viciousness, and both of discontent.

If women are expected to do the same work as men, we must teach them the same things.

Thinking is the talking of the soul with itself.

The most effective kind of education is that a child should play amongst lovely things.

As empty vessels make the loudest sound, so they that have the least wit are the greatest blabbers.

Life must be lived as play.

We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light.
