God is unknown; anything we said about God has no validity, because our knowledge about Him is zero, absolutely nothing!

If a man gives you a harsh winter, give him back something unexpected: The warm spring!

The demands of the science, of the ethics and of the reason are superior to the demands of the people!

Innovations, free thinking is blowing like a storm; those that stand in front of it, ignorant scholars like you, false scientists, perverse conservatives, obstinate goats, resisting mules are being crushed under the weight of these innovations.

When everything is going greatly, you can never see the real faces of the people! Wait for the hard times to see the true face!
