Incredulity is not wisdom, but the worst kind of folly. It is folly, because it causes ignorance and mistake, with all the consequents of these; and it is very bad, as being accompanied with disingenuity, obstinacy, rudeness, uncharitableness, and the like, bad dispositions; from which credulity itself, the other extreme sort of folly, is exempt.
If a fool would persist in his folly he would become wise.
Hypocrisy is folly. It is much easier, safer, and pleasanter to be the thing which a man aims to appear, than to keep up the appearance of what he is not.
No folly is more costly than the folly of intolerant idealism.
Prudence is the necessary ingredient in all the virtues, without which they degenerate into folly and excess.
Uncertainty and expectation are the joyous of life. Security is an insipid thing, and the overtaking and possessing or a wish discovers the folly of the chase.
All human wisdom, to divine, is folly.
The taxes were indeed very heavy, and if those laid on by the government were the only ones we had to pay, we might more easily discharge them; but we have many others, and much more grievous to some of us. We are taxed twice as much by our idleness, three times by our pride, and four times as much by our folly; and from these taxes the commissioners cannot ease or deliver us, by allowing an abatement.
There is nothing in life so irrational, that good sense and chance may not set it to rights; nothing so rational, that folly and chance may not utterly confound it.
It is virtue, to fly vice; and the highest wisdom to have lived free from folly.
Health is so necessary to all the duties as well as pleasures of life that the crime of squandering it is equal to the folly.
We frequently fall into error and folly, not because the true principles of action are not known, but because for a time they are not remembered; he may, therefore, justly be numbered among the benefactors of mankind who contracts the great rules of life into short sentences that may early be impressed on the memory, and taught by frequent recollection to occur habitually to the mind.
It is characteristic of our age to endeavour to replace virtues by technology. That is to say, wherever possible we strive to use methods of physical or social engineering to achieve goals which our ancestors thought attainable only by the training of character. Thus we try so far as possible to make contraception take the place of chastity, and anesthetics to take the place of fortitude; we replace resignation by insurance policies and munificence by the Welfare state. It would be idle romanticism to deny that such techniques and institutions are often less painful and more efficient methods of achieving the goods and preventing the evils which unaided virtue once sought to achieve and avoid. But it would be an equal and opposite folly to hope that the take-over of virtue by technology may one day be complete.
Politeness is not always a sign of wisdom. but the want of it always leaves room for a suspicion of folly, if folly and imprudence are the same.
There is no outward sign of politeness which has not a deep, moral reason. Behavior is a mirror in which every one shows his own image. There is a politeness of the heart akin to love, from which springs the easiest politeness of outward behavior... Politeness is not always a sign of wisdom, but the want of it always leaves room for the suspicion of folly.
Obstinacy and heat in argument are surest proofs of folly. Is there anything so stubborn, obstinate, disdainful, contemplative, grave, or serious, as an ass?
Every man’s vanity ought to be his greatest shame; and every man’s folly ought to be his greatest secret.
Men are contented to be laughed at for their wit, but not for their folly.
There is no vice or folly that requires so much nicety and skill to manage as vanity; nor any which by ill management makes so contemptible a figure.
Wit implies hatred or contempt of folly and crime, produces its effects by brisk shocks of surprise, uses the whip of scorpions and the branding iron, stabs, stings, pinches, tortures, goads, teases, corrodes, undermines.
