Who said “A little credulity helps one on through life very smoothly.”?

“Man is a credulous animal, and must believe something; in the absence of good grounds for belief, he will be satisfied with bad ones.”

“The fact that a believer is happier than a skeptic is no more to the point than the fact that a drunken man is happier than a sober one. The happiness of credulity is a cheap and dangerous quality.”

“Our credulity is greatest concerning the things we know least about. And since we know least about ourselves, we are ready to believe all that is said about us. Hence the mysterious power of both flattery and calumny.”

“The most positive men are the most credulous.”

“The only disadvantage of an honest heart is credulity.”

“I'll not listen to reason. Reason always means what someone else has got to say.”

“A wise parent humors the desire for independent action, so as to become the friend and advisor when his absolute rule shall cease.”

“People may flatter themselves just as much by thinking that their faults are always present to other people's minds, as if they believe that the world is always contemplating their individual charms and virtues.”

“To be sure a stepmother to a girl is a different thing to a second wife to a man!”

“How easy it is to judge rightly after one sees what evil comes from judging wrongly!”

“Sometimes one likes foolish people for their folly, better than wise people for their wisdom.”
