Knowledge is of no value unless you put it into practice.

The knowledge of anything, since all things have causes, is not acquired or complete unless it is known by its causes.

Talk radio can't work unless you have the kind of independence you get by being part of an independent news network. You can't be beholden to an agenda, and that's what I like about Fox: It doesn't have one.

Charity is injurious unless it helps the recipient to become independent of it.

Never lose sight of the fact that all human felicity lies in man's imagination, and that he cannot think to attain it unless he heeds all his caprices. The most fortunate of persons is he who has the most means to satisfy his vagaries.

You can't do it unless you can imagine it.

I'm not sure. But that bless-his/her-heart kind of melancholic humor is among my favorite things in the world. I guess it exposes a kind of humanity - or that's the hope, at least - a kind of grudging respect for human frailty. Unless it's actually kicking human frailty while it's down - I'm not sure.

Humor is very very risky, particularly for a candidate, unless he's been in so long that it just doesn't matter, and he's not running for president. But it's just that people are so sensitive and so touchy, and you're just going to upset somebody without ever realizing it.

Humor has become so cliche and boring that nothing's funny anymore unless it involves something totally disgusting that offends somebody or makes them feel really uncomfortable.

A pun is the lowest form of humor, unless you thought of it yourself.

With all the... success that I've been lucky enough to get? That doesn't happen unless the home life is solid.

A house is no home unless it contain food and fire for the mind as well as for the body.

Whether rich or poor, a home is not a home unless the roots of love are ever striking deeper through the crust of the earthly and the conventional, into the very realities of being, not consciously always; seldom, perhaps; the simplicity of loving grows by living simply near nature and God.

Housework is what a woman does that nobody notices unless she hasn't done it.

Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks.

The revolutionary breakthrough will come with rockets that are fully and rapidly reusable. We will never conquer Mars unless we do that. It'll be too expensive. The American colonies would never have been pioneered if the ships that crossed the ocean hadn't been reusable.

Something as curious as the monarchy won't survive unless you take account of people's attitudes. After all, if people don't want it, they won't have it.

Redemption basically is about holistic health, if you want to translate it into modern parlance. What I suggest - based on the Christian tradition but not often preached - is that you can't enter into the fullness of the Pascal mystery of the redemption unless there is a radical transformation of motivation within you.

Capital is reckless of the health or length of life of the laborer, unless under compulsion from society.

Happiness isn't happiness unless there's a violin-playing goat.

In the end, you're trying to find God. That's the result of not being satisfied. And it doesn't matter how much money, or property, or whatever you've got, unless you're happy in your heart, then that's it. And unfortunately, you can never gain perfect happiness unless you've got that state of consciousness that enables that.

Life is not an easy matter... You cannot live through it without falling into frustration and cynicism unless you have before you a great idea which raises you above personal misery, above weakness, above all kinds of perfidy and baseness.

It is not enough for us to restrain from doing evil, unless we shall also do good.

We shall not be happy unless we live like good animals, unless we enjoy the exercise of the ordinary functions of life: eating, sleeping, loving, walking, running, swimming, riding, sailing.
