Gratitude is a soil on which joy thrives.

What will people say-in these words lies the tyranny of the world, the whole destruction of our natural disposition, the oblique vision of our minds. These four words hold sway everywhere.

People look with sympathetic eyes only at the blossom and the fruit, and disregard the long period of transition during which the one is ripening into the other.

Discontent is the source of all trouble,but also of all progress, in individuals and nations.

What is all our knowledge worth? We do not even know what the weather will be tomorrow.

It is only when one is thoroughly true that there can be purity and freedom. Falsehood always punishes itself.

We consider it tedious to talk of the weather, and yet there is nothing more important.
