The Christian religion teaches us to imitate a God that is cruel, insidious, jealous, and implacable in his wrath.

The most dangerous madmen are those created by religion, and people whose aim is to disrupt society always know how to make good use of them on occasion.

All things must be examined, debated, investigated without exception and without regard for anyone's feelings... We must run roughshod over all these ancient puerilities, overturn the barriers that reason never erected, give back to the arts and sciences the liberty that is so precious to them.

Only the bad man is alone.

Whatever dressing one gives to mushrooms, to whatever sauces our Apiciuses put them, they are not really good but to be sent back to the dungheap where they are born.

He whom we call a gentleman is no longer the man of Nature.

The good of the people must be the great purpose of government. By the laws of nature and of reason, the governors are invested with power to that end. And the greatest good of the people is liberty. It is to the state what health is to the individual.
