There is only one virtue, justice; only one duty, to be happy; only one corollary, not to overvalue life and not to fear death.
Denis DiderotMankind have banned the Divinity from their presence; they have relegated him to a sanctuary; the walls of the temple restrict his view; he does not exist outside of it.
Denis DiderotThe philosopher forms his principles on an infinity of particular observations. He does not confuse truth with plausibility, he takes for truth what is true, for false what is false, for doubtful what is doubtful, and probable what is probable. The philosophical spirit is thus a spirit of observation and accuracy.
