The hopeless don't revolt, because revolution is an act of hope.

Prisons are universities of crime, maintained by the state.

Each individual is a cosmos of organs, each organ is a cosmos of cells, each cell is a cosmos of infinitely small ones; and in this complex world, the well-being of the whole depends entirely on the sum of well-being enjoyed by each of the least microscopic particles of organized matter. A whole revolution is thus produced in the philosophy of life.

You know how I always believe in the future. Without disorder, the revolution is impossible; knowing that, I did not lose hope, and I do not lose it now.

When one has talent, everything contributes to its development.

Struggle so that all may live this rich, overflowing life. And be sure that in this struggle you will find a joy greater than anything else can give.

Think about the world you want to live and work in. What do you need to know to build the world? Demand that your teachers teach you that.
