"There is a superstition in avoiding superstition, when men think to do best, if they go furthest from the superstition, formerly received; therefore care would be had that (as it fareth in ill purgings) the good be not taken away with the bad; which commonly is done, when the people is the reformer."

"The superstitions of today are the scientific facts of tomorrow."

"Reason shapes the future, but superstition infects the present."

"Superstition! A fatal flaw for a regime whose legitimacy comes entirely from religion."

"Some of the truths, now called “exploded superstitions,” will be discovered to be facts and the relics of ancient knowledge and wisdom...."

"If we hold our opinions merely on historical grounds, on the authority of legions of the most eminent Sages, Neo-Platonists, Mystics of all the ages, from Pythagoras down to the eminent Scientists and Professors of the present century, who, if they reject “gods,” believe in “spirits,” shall we consider such authorities as weak-minded and foolish...?"

"A visitor to Niels Bohr's country cottage, noticing a horseshoe hanging on the wall, teasing the eminent scientist about this ancient superstition. 'Can it be true that you, of all people, believe it will bring you luck?' 'Of course not,' replied Bohr, 'but I understand it brings you luck whether you believe it or not.'"

"It is the business of science to offer rational explanations for all the events in the real world, and any scientist who calls on God to explain something is falling down on his job. This applies as much to the start of the expansion as to any other event. If the explanation is not forthcoming at once, the scientist must suspend judgment: but if he is worth his salt he will always maintain that a rational explanation will eventually be found. This is the one piece of dogmatism that a scientist can allow himself—and without it science would be in danger of giving way to superstition every time that a problem defied solution for a few years."

"Thus identified with astronomy, in proclaiming truths supposed to be hostile to Scripture, Geology has been denounced as the enemy of religion. The twin sisters of terrestrial and celestial physics have thus been joint-heirs of intolerance and persecution—unresisting victims in the crusade which ignorance and fanaticism are ever waging against science. When great truths are driven to make an appeal to reason, knowledge becomes criminal, and philosophers martyrs. Truth, however, like all moral powers, can neither be checked nor extinguished. When compressed, it but reacts the more. It crushes where it cannot expand—it burns where it is not allowed to shine. Human when originally divulged, it becomes divine when finally established. At first, the breath of a rage—at last it is the edict of a god. Endowed with such vital energy, astronomical truth has cut its way through the thick darkness of superstitious times, and, cheered by its conquests, Geology will find the same open path when it has triumphed over the less formidable obstacles of a civilized age."

"Foul Superstition! howsoe'er disguised, Idol, saint, virgin, prophet, crescent, cross, For whatsoever symbol thou art prized, Thou sacerdotal gain, but general loss! Who from true worship's gold can separate thy dross?"

"The true wisdom of man consists in the knowledge of God the Creator and Redeemer. This knowledge is naturally implanted in us, and the end of it ought to be the worship of God rightly performed, or reverence for the Deity accompanied by fear and love. But this seed is corrupted by ignorance, whence arises superstitious worship."
