All science is experiential; but all experience must be related back to and derives its its validity from the conditions and context of consciousness in which it arises, i.e., the totality of our nature.

To mistrust science and deny the validity of scientific method is to resign your job as a human. You'd better go look for work as a plant or wild animal.

There's a security, a validity of knowing that it's legal. It's hard to put into words. It's just a feeling, I guess - something about saying vows in front of the people around you who love and support you.

No force can conquer the service personnel and people who, in support of their great leader, have turned out in the struggle to defend their country with confidence in the validity of their cause and their own strength - this is a law and a truth taught by history.

When I'm writing, I'm constantly thinking about myself, because it's the only experience I have to draw on. And I don't see an exact reflection of myself in every face in the audience, but I know that my songs have validity to them, and that's why the fans are there.

The only relevant test of the validity of a hypothesis is comparison of prediction with experience.

A steady diet of the higher truths might prove exhausting, but it's important that we acknowledge their validity and celebrate their survival.

I believe that history has shape, order, and meaning; that exceptional men, as much as economic forces, produce change; and that passe abstractions like beauty, nobility, and greatness have a shifting but continuing validity.

A rumor is a social cancer: it is difficult to contain and it rots the brains of the masses. However, the real danger is that so many people find rumors enjoyable. That part causes the infection. And in such cases when a rumor is only partially made of truth, it is difficult to pinpoint exactly where the information may have gone wrong. It is passed on and on until some brave soul questions its validity; that brave soul refuses to bite the apple and let the apple eat him. Forced to start from scratch for the sake of purity and truth, that brave soul, figuratively speaking, fully amputates the information in order to protect his personal judgment. In other words, his ignorance is to be valued more than the lie believed to be true.

Wherever morality is based on theology, wherever the right is made dependent on divine authority, the most immoral, unjust, infamous things can be justified and established. I can found morality on theology only when I myself have already defined the Divine Being by means of morality. In the contrary case, I have no criterion of the moral and immoral, but merely an unmoral, arbitrary basis, from which I may deduce anything I please. Thus, if I would found morality on God, I must first of all place it in God: for Morality, Right, in short, all substantial relations, have their only basis in themselves, can only have a real foundation-such as truth demands-when they are thus based. (?) Where man is in earnest about ethics, they have in themselves the validity of a divine power. If morality has no foundation in itself, there is no inherent necessity for morality; morality is then surrendered to the groundless arbitrariness of religion.

So let me tell you that in the last analysis, this world of God's ? I don't accept it, even though I know that it exists, and I don't admit its validity in any way. It isn't God I don't accept, you see; it's the world created by Him, the world of God I don't accept and cannot agree to accept.

A philosopher is a lover of wisdom, not of knowledge, which for all its great uses ultimately suffers from the crippling effect of ephemerality. All knowledge is transient linked to the world around it and subject to change as the world changes, whereas wisdom, true wisdom is eternal immutable. To be philosophical one must love wisdom for its own sake, accept its permanent validity and yet its perpetual irrelevance. It is the fate of the wise to understand the process of history and yet never to shape it.

The motive behind criticism often determines its validity. Those who care criticize where necessary. Those who envy criticize the moment they think that they have found a weak spot.

Life is not to be taken seriously, as we are really temporary here. We are like a pre-paid card with limited validity. If we are lucky, we may last another 50 years. And 50 years is just 2,500 weekends. Do we really need to get so worked up? It's ok, bunk a few classes, goof up a few interviews, fall in love. We are people, not programmed devices.

If the concept of God has any validity or any use, it can only be to make us larger, freer, and more loving. If God cannot do this, then it is time we got rid of Him.

I consider 'Dr. Horrible' a tremendous success. The fact that it won an Emmy I just think lends validity to what we were doing and the point we were trying to make: taking the power into someone else's hands and changing the world.

The problem for those who assert biblical authority in support of traditional definitions of marriage is that one could with equal validity assert that the lending of money or certain kinds of haircuts are forbidden by God or that slavery and the subjugation of women are authorized by the Lord.
