“The ‘stream’ we call science always flows forward; sometimes reactionary beavers block its flow, but the stream is never defeated by this; it accumulates, gathers strength; its waters get over the barrage and continue on their course. The advancement of science is the advancement of God, for science is nothing but human intelligence, and human intelligence is the most valuable treasure God has bequeathed us.”

“What have you done for science today? Stop doing things for God! He doesn't need anything. Do something for science, for God's sake!”

“One of the most tragicomic things in life is that when a man makes an imaginary thing – such as a religion – as his own flag and carries it all his life and even dies for it! An intelligent man has only one flag: Flag of reason and science!”

“I’m saying that the leaders of the church have locked the sacred cow called science in the stable and they won’t let anybody enter; they should open it immediately so that we can milk that cow in the name of humanity and thus find the truth.”

“Humanity must have a speed of advance higher than the speed of advance of cosmic disasters or big global catastrophes!”

“Religion now has degenerated and it has turned into a wolf; it has opened its mouth to show his ugly teeth; its spreading fear instead of love; and science has hidden in a corner like a lamb, trembling with fear!”

“Do not discuss the religious matters with people; do not waste your valuable time to discuss the untruth! Your time is short; spend it for the science and the art!”
