Frankly, these days, without a theory to go with it, I can't see a painting.

But this is not to say that the society which inflicts capital punishment commits murder. Murder is an offensive act. The term cannot be applied legitimately to any defensive act. And capital punishment, however ineffective it may be and through whatever ignorance it may be resorted to, is a strictly defensive act,—at least in theory.

It really is a nice theory. The only defect I think it has is probably common to all philosophical theories. It's wrong.

The implications of these considerations justify the statement that all empirically verifiable knowledge even the commonsense knowledge of everyday life - involves implicitly, if not explicitly, systematic theory in this sense.

Mathematical science is in my opinion an indivisible whole, an organism whose vitality is conditioned upon the connection of its parts. For with all the variety of mathematical knowledge, we are still clearly conscious of the similarity of the logical devices, the relationship of the ideas in mathematics as a whole and the numerous analogies in its different departments. We also notice that, the farther a mathematical theory is developed, the more harmoniously and uniformly does its construction proceed, and unsuspected relations are disclosed between hitherto separate branches of the science. So it happens that, with the extension of mathematics, its organic character is not lost but only manifests itself the more clearly.

He was, however, speaking to a representative of government, the police. And it is to government that one goes 'for a redress of grievances,' to use an almost forgotten phrase of the First Amendment. But it is said that the purpose was 'to cause inconvenience and annoyance.' Since when have we Americans been expected to bow submissively to authority and speak with awe and reverence to those who represent us? The constitutional theory is that we the people are the sovereigns, the state and federal officials only our agents. We who have the final word can speak softly or angrily. We can seek to challenge and annoy, as we need not stay docile and quiet.

Believing that the power to destroy belongs to the Creator alone I affirm... that any theory which, when carried out, demands the annihilation of force, is necessarily erroneous.

The rich possess ample means to realize any theory they may chuse to adopt in the education of their children, regardless of the cost; but it is not so with him whose Subsistence is derived from industry.

Blind commitment to a theory is not an intellectual virtue; it is an intellectual crime.

By the theory of our Government majorities rule, but this right is not an arbitrary or unlimited one. It is a right to be exercised in subordination to the Constitution and in conformity to it. One great object of the Constitution was to restrain majorities from oppressing minorities or encroaching upon their just rights. Minorities have a right to appeal to the Constitution as a shield against such oppression.

As for everything else, so for a mathematical theory: beauty can be perceived but not explained.

Democracy is the theory that the common people know what they want, and deserve to get it good and hard.

I am now convinced that theoretical physics is actually philosophy. It has revolutionized fundamental concepts, e. g., abut space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics). It has taught us new methods of thinking (complimentarity), which are applicable far beyond physics.

It is an acknowledged truth in philosophy that a just theory will always be confirmed by experiment.

Probability is expectation founded upon partial knowledge. A perfect acquaintance with all the circumstances affecting the occurrence of an event would change expectation into certainty, and leave neither room nor demand for a theory of probabilities.

Although it may be difficult in theory to know what is just and equal, the practical difficulty of inducing those to forbear who can, if they like, encroach, is far greater, for the weaker are always asking for equality and justice, but the stronger care for none of these things.

Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot, but does not really bring us any closer to the secret of the "old one." I, at any rate, am convinced that He does not throw dice.

When we descend to details, we can prove that no one species has changed (i.e., we cannot prove that a single species has changed): nor can we prove that the supposed changes are beneficial, which is the groundwork of the theory. Nor can we explain why some species have changed and others have not.

I call it the Madman Theory, Bob. I want the North Vietnamese to believe I've reached the point where I might do anything to stop the war. We'll just slip the word to them that, for God's sake, you know Nixon is obsessed about Communism. We can't restrain him when he's angry and he has his hand on the nuclear button and Ho Chi Minh himself will be in Paris in two days begging for peace.

The rose is a rose, And was always a rose. But now the theory goes That the apple's a rose, And the pear is, and so's The plum, I suppose. The dear only knows What will next prove a rose. You, of course, are a rose But were always a rose.

In theory it is easy to convince an ignorant person; in actual life, men not only object to offer themselves to be convinced, but hate the man who has convinced them.

A theory is a good theory if it satisfies two requirements: it must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations.

A prose writer gets tired of writing prose, and wants to be a poet. So he begins every line with a capital letter, and keeps on writing prose.
