Heraclitus

Ever-newer waters flow on those who step into the same rivers.

He who does not expect will not find out the unexpected, for it is trackless and unexplored

The waking have one common world, but the sleeping turn aside each into a world of his own

All things come out of the one, and the one out of all things.

Hide our ignorance as we will, an evening of wine soon reveals it.

Nothing endures but change. There is nothing permanent except change. All is flux, nothing stays still.

The people must fight for their laws as for their walls.

Eyes and ears are poor witnesses to people if they have uncultured souls.

Even sleepers are workers and collaborators on what goes on in the universe.

No one that encounters prosperity does not also encounter danger.

Greater dooms win greater destinies.

Everything flows and nothing abides. Everything gives way and nothing stays fixed.

You cannot step into the same river twice.

A man's character is his fate.

All things are in a state of flux.

Big results require big ambitions.

Religion is a disease, but it is a noble disease.

The majority of people have no understanding of the things with which they daily meet, nor, when instructed, do they have any right knowledge of them, although to themselves they seem to have.

If you do not hope, you will not win that which is not hoped for, since it is unattainable and inaccessible.

All things flow, nothing abides.

Time is a game played beautifully by children.
