Copernicus Quotes
All the men who are now called discoverers, in every matter ruled by thought, have been men versed in the minds of their predecessors, and learned in what had been before them. There is not one exception. I do not say that every man has made direct acquantance with the whole of his mental ancestry... But... it is remarkable how many of the greatest names in all departments of knowledge have been real antiquaries in their several subjects.
I may cite among those... in science, Aristotle, Plato, Ptolemy, Euclid, Archimedes, Roger Bacon, Copernicus, Francis Bacon, Ramus, Tycho Brahe, Galileo, Napier, Descartes, Leibnitz, Newton, Locke.
Augustus De Morgan
It may be, however, sufficient to say, that wherever the church has had power it has been a crime for any man to speak his honest thought. No church has ever been willing that any opponent should give a transcript of his mind. Every church in power has appealed to brute force, to the sword, for the purpose of sustaining its creed. Not one has had the courage to occupy the open field. The church has not been satisfied with calling Infidels and unbelievers blasphemers. Each church has accused nearly every other church of being a blasphemer. Every pioneer has been branded as a criminal. The Catholics called Martin Luther a blasphemer, and Martin Luther called Copernicus a blasphemer. Pious ignorance always regards intelligence as a kind of blasphemy. Some of the greatest men of the world, some of the best, have been put to death for the crime of blasphemy, that is to say, for the crime of endeavoring to benefit their fellow-men.
Robert G. Ingersoll
I am a Christian, that is, I believe in the divinity of Christ, as did Tycho Brahe, Copernicus, Descartes, Newton, Fermat, Leibniz, Pascal, Grimaldi, Euler, Guldin; Boscovich, Gerdil, as did all the great astronomers, physicist and geometricians of past ages.
