I hate books; they only teach people to talk about what they don't understand.

When my reason is afloat, my faith cannot long remain in suspense, and I believe in God as firmly as in any other truth whatever; in short, a thousand motives draw me to the consolatory side, and add the weight of hope to the equilibrium of reason.

We can never put ourselves in the shoes of children; we cannot fathom their thoughts, we lend them ours; and always following ourown reasoning, we stuff their heads with extravagance and error.

The training of children is a profession, where we must know how to waste time in order to save it.

Childhood is the sleep of reason.

Smell is the sense of memory and desire.

The passions are the voice of the body.
