One is never so dangerous when one has no shame, than when one has grown too old to blush.

Religions are the cradles of despotism.

Every principle is a judgment, every judgment the outcome of experience, and experience is only acquired by the exercise of the senses; whence it follows that religious principles bear upon nothing whatever and are not in the slightest innate. Ignorance and fear, you will repeat to them, ignorance and fear - those are the twin bases of every religion.

Your service will be arduous, it will be painful and rigorous, and the slightest delinquencies will be requited immediately with corporal and afflicting punishments; hence, I must recommend to you prompt exactness, submissiveness, and total self-abnegation that you be enabled to heed naught but our desires; let them be your laws, fly to do their bidding, anticipate them, cause them to be born.

It requires only two things to win credit for a miracle: a mountebank and a number of silly women.

Truth titillates the imagination far less than fiction.

All, all is theft, all is unceasing and rigorous competition in nature; the desire to make off with the substance of others is the foremost - the most legitimate - passion nature has bred into us and, without doubt, the most agreeable one.
