Even in the most insignificant details of our daily life, none of us can be said to constitute a material whole, which is identical for everyone, and need only be turned up like a page in an account-book or the record of a will; our social personality is created by the thoughts of other people.

It is always thus, impelled by a state of mind which is destined not to last, we make our irrevocable decisions

We do not succeed in changing things according to our desire, but gradually our desire changes.

We are at times too ready to believe that the present is the only possible state of things.

We become moral when we are unhappy.

The human plagiarism which is most difficult to avoid, for individuals... is the plagiarism of ourselves.

When we have passed a certain age, the soul of the child we were and the souls of the dead from whom we have sprung come to lavish on us their riches and their spells.
