For ten centuries Christianity, armed with the omnipotence of the Church and State and opposed by no competition, was able to deprave, debase, and falsify the mind of Europe. It had no competitors, because outside the Church there was neither thinkers nor educated persons. It alone taught, it alone spoke and wrote, it alone taught.
 Mikhail Bakunin

Quotes from the same author

If God is, man is a slave; now, man can and must be free; then, God does not exist. I defy anyone whomsoever to avoid this circle; now, therefore, let all choose.
 Mikhail Bakunin

 Mikhail Bakunin
