"It was idiotic to be superstitious."
"For my own part I would as soon be descended from that heroic little monkey, who braved his dreaded enemy in order to save the life of his keeper; or from that old baboon, who, descending from the mountains, carried away in triumph his young comrade from a crowd of astonished dogs—as from a savage who delights to torture his enemies, offers up bloody sacrifices, practices infanticide without remorse, treats his wives like slaves, knows no decency, and is haunted by the grossest superstitions."

A superstition is any belief or practice considered by non-practitioners to be irrational or supernatural. It is commonly applied to beliefs and practices surrounding luck, fate, magic, amulets, astrology, fortune telling, spirits, and certain paranormal entities, particularly the belief that future events can be foretold by specific unrelated prior events.

"All superstitions exist at least in part to satisfy the emotional needs of the experiencing subject. The chief emotions that give rise to superstitious beliefs are fear and anxiety, and they are often reinforced by a disposition to fantasy and mental laziness."
"“Superstition” is simply a derogative term for a belief about the supernatural that you don’t share. Why should it be socially acceptable to make fun of psychics and not priests? What’s the difference between crossing yourself or hanging a mezuzah outside your door and avoiding black cats? Believing that you’ve been abducted by aliens or that Elvis is alive is, on its face, no sillier than believing that Christ rose from the dead or that God parted the Red Sea so that Moses and his followers might traverse it. People who believe that God heeds their prayers have probably waived the right to mock people who talk to trees and guardian angels or claim to channel the spirits of Native Americans."
"The three great things that govern mankind are reason, passion, and superstition. The first governs a few, the two last share the bulk of mankind, and possess them in their turns; but superstition most powerfully and produces the greatest mischief."
"When man seized the loadstone of science, the loadstar of superstition vanished in the clouds."
