Quotations

For, the sun is not inappropriately called by some people the lantern of the universe, its mind by others, and its ruler by still others.

De revolutionibus orbium coelestium (1543)

For when a ship is floating calmly along, the sailors see its motion mirrored in everything outside, while on the other hand they suppose that they are stationary, together with everything on board. In the same way, the motion of the earth can unquestionably produce the impression that the entire universe is rotating.

De revolutionibus orbium coelestium (1543)

For I am not so enamored of my own opinions that I disregard what others may think of them. I am aware that a philosopher’s ideas are not subject to the judgment of ordinary persons, because it is his endeavor to seek the truth in all things, to the extent permitted to human reason by God. Yet I hold that completely erroneous views should be shunned. Those who know that the consensus of many centuries has sanctioned the conception that the earth remains at rest in the middle of the heaven as its center would, I reflected, regard it as an insane pronouncement if I made the opposite assertion that the earth moves.

De revolutionibus orbium coelestium (1543)

To know the mighty works of God, to comprehend His wisdom and majesty and power; to appreciate, in degree, the wonderful workings of His laws, surely all this must be a pleasing and acceptable mode of worship to the Most High, to whom ignorance cannot be more grateful than knowledge.

As quoted in Poland : The Knight Among Nations (1907) by Louis E. Van Norman

Finally we shall place the Sun himself at the center of the Universe. All this is suggested by the systematic procession of events and the harmony of the whole Universe, if only we face the facts, as they say, “with both eyes open.”

As quoted in The Copernican Revolution : Planetary Astronomy in the Development of Western Thought (1957) by Thomas S. Kuhn
