A men whose every word is nothing but the truth is not a human being but a god! Gods do not die, whereas Aristotle is lying in a grave now.

But just one gram of suspicion weighs heavier than a kilo of truth!

History of science is a relay race, my painter friend. Copernicus took over his flag from Aristarchus, from Cicero, from Plutarch; and Galileo took that flag over from Copernicus.

I owe all my knowledge to the German inventor, Johannes Gutenberg!

If the world is turning, even the church can’t stop it; if it isn’t turning, nobody can go out and make it turn.

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. You are nothing but ants standing in front of the giants; nothing but chicks trying to challenge roaring volcanoes!

It is better to go near the truth and be imprisoned than to stay with the wrong and roam about freely, master Galilei. In fact, getting attached to falsity is terrible slavery, and real freedom is only next to the right.

It’s very dangerous to invent something in our times; ostentatious men of the other world, who are hostile to innovations, roam about angrily. To live in peace, one has to stay away from innovations and new ideas. Innovations, like trees, attract the most destructive lightnings to themselves.

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.

My dear friend, to be both powerful and fair has always been difficult for mankind. Power and justice have always been seen like day and night; this being the case, when one of them is there the other disappears.

New ideas seem like frightening ghosts to people at the beginning; they run away from them for a long time, but they get tired of it in the end!

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!

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.

The mind God is looking for in man is a doubting, questioning mind, not a dogmatic mind; dogmatic reasoning is wrong reasoning. Dogmatic reason ties a huge rock to a man’s foot and stops him forever from advancing.

There are so many stars shining in the sky, so many beautiful things winking at you, but when Venus comes out, all the others are waned, they are pushed to the background.

There must be a marsh in the brains of these men or there would not be so many frogs of wrong ideas gathered in their heads.

Truths are immortal, my dear friend; they are immortal like God! What we call a falsity is like a fruit; it has a certain number of days; it is bound to decay. Whereas, what we call truth is like gold; days, months, even centuries can hide gold, can overlook it but they can never make it decay.
