Without the Utopians of other times, men would still live in caves, miserable and naked. It was Utopians who traced the lines of the first City.....Out of generous dreams come beneficial realities. Utopia is the principle of all progress, and the essay into a better future.

One thing above all gives charm to men's thoughts, and this is unrest. A mind that is not uneasy irritates and bores me.

Those who have given themselves the most concern about the happiness of peoples have made their neighbors very miserable.

Custom alone regulates morals.

What can be more foolish than to think that all this rare fabric of heaven and earth could come by chance, when all the skill of art is not able to make an oyster!

It is good to collect things, but it is better to go on walks.

To imagine is everything, to know is nothing at all.
