“Sir, I have found you an argument; but I am not obliged to find you an understanding.”

The wise man applauds he who he thinks most virtuous; the rest of the world applauds the wealthy.

Pride is a vice, which pride itself inclines every man to find in others, and to overlook in himself.

Ignorance, when it is voluntary, is criminal; and he may be properly charged with evil who refused to learn how he might prevent it.

He who waits to do a great deal of good at once will never do anything.

If your determination is fixed, I do not counsel you to despair. Few things are impossible to diligence and skill. Great works are performed not by strength, but perseverance.

A contempt of the monuments and the wisdom of the past, may be justly reckoned one of the reigning follies of these days, to which pride and idleness have equally contributed.

All travel has its advantages. If the passenger visits better countries, he may learn to improve his own. And if fortune carries him to worse, he may learn to enjoy it.

A wise man will make haste to forgive, because he knows the true value of time, and will not suffer it to pass away in unnecessary pain.

Whoever commits a fraud is guilty not only of the particular injury to him who he deceives, but of the diminution of that confidence which constitutes not only the ease but the existence of society.

Courage is reckoned the greatest of all virtues; because, unless a man has that virtue, he has no security for preserving any other.

Deviation from Nature is deviation from happiness.

Advice is seldom welcome. Those who need it most, like it least.

No man will be a sailor who has contrivance enough to get himself into a jail; for being in a ship is being in a jail, with the chance of being drowned. A man in a jail has more room, better food, and commonly better company.

When once the forms of civility are violated, there remains little hope of return to kindness or decency.

Language is the dress of thought; every time you talk your mind is on parade.

It is better to live rich than to die rich.

The core of science is not a mathematical modeling–it is intellectual honesty. It is a willingness to have our certainties about the world constrained by good evidence and good argument.

You almost never get the pleasure of seeing that you won the argument in real time. People just don’t like to publicly change their minds. They change their minds in private.

The difference between science and religion is the difference between a willingness to dispassionately consider new evidence and new arguments , and a passionate unwillingness to do so.

The thing I hate about an argument is that it always interrupts a discussion.

One could surely argue that the Buddhist tradition, taken as a whole, represents the richest source of contemplative wisdom that any civilization has produced.

If someone doesn’t value evidence, what evidence are you going to provide that proves they should value evidence. If someone doesn’t value logic, what logical argument would you invoke to prove they should value logic?

An argument can be logically valid, but unsound in that it contains a false premise and, therefore, leads to a false conclusion (e.g., Scientists are smart; smart people do not make mistakes; therefore, scientists do not make mistakes).

The fear of punishment, the desire of reward, the sense of duty, are all useful arguments, in their way, to persuade people to holiness. But they are all weak and powerless, until a person loves Christ.
