Politics is for the moment and equation is for eternity.

A theory should not attempt to explain all the facts, because some of the facts are wrong.

Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.

The problem is that our ideas are sticky: once we produce a theory, we are not likely to change our minds....

My main reason for scepticism about the Huxley/Sagan theory is that the human brain is demonstrably eager to see faces in random patterns, as we know from scientific evidence, on top of the numerous legends about faces of Jesus, or the Virgin Mary, or Mother Teresa, being seen on slices of toast, or pizzas, or patches of damp on a wall. This eagerness is enhanced if the pattern departs from randomness in the specific direction of being symmetrical.

The practice of that which is ethically best — what we call goodness or virtue — involves a course of conduct which, in all respects, is opposed to that which leads to success in the cosmic struggle for existence. In place of ruthless self-assertion it demands self-restraint; in place of thrusting aside, or treading down, all competitors, it requires that the individual shall not merely respect, but shall help his fellows... It repudiates the gladiatorial theory of existence... Laws and moral precepts are directed to the end of curbing the cosmic process.

...the specious meditations, speculations, and theories of mankind are but a kind of insanity, only there is no one to stand by and observe it.

Every person should embrace those [dogmas] that he, being the best judge of himself, feels will do most to strengthen in him love of justice.

The essence of science is that it is always willing to abandon a given idea for a better one; the essence of theology is that it holds its truths to be eternal and immutable.

If someone were to propose that the planets go around the sun because all planet matter has a kind of tendency for movement, a kind of motility, let us call it an ‘oomph,’ this theory could explain a number of other phenomena as well. So this is a good theory, is it not? No. It is nowhere near as good as the proposition that the planets move around the sun under the influence of a central force which varies exactly inversely as the square of the distance from the center. The second theory is better because it is so specific; it is so obviously unlikely to be the result of chance. It is so definite that the barest error in the movement can show that it is wrong; but the planets could wobble all over the place, and, according to the first theory, you could say, ‘Well, that is the funny behavior of the ‘oomph.

Study, along the lines which the theologies have mapped, will never lead us to discovery of the fundamental facts of our existence. That goal must be attained by means of exact science and can only be achieved by such means. The fact that man, for ages, has superstitiously believed in what he calls a God does not prove at all that his theory has been right. There have been many gods – all makeshifts, born of inability to fathom the deep fundamental truth. There must be something at the bottom of existence, and man, in ignorance, being unable to discover what it is through reason, because his reason has been so imperfect, undeveloped, has used, instead, imagination, and created figments, of one kind or another, which, according to the country he was born in, the suggestions of his environment, satisfied him for the time being. Not one of all the gods of all the various theologies has ever really been proved. We accept no ordinary scientific fact without the final proof; why should we, then, be satisfied in this most mighty of all matters, with a mere theory?

Destruction of false theories will not decrease the sum of human happiness in future, any more than it has in the past... The days of miracles have passed. I do not believe, of course, that there was ever any day of actual miracles. I cannot understand that there were ever any miracles at all. My guide must be my reason, and at thought of miracles my reason is rebellious. Personally, I do not believe that Christ laid claim to doing miracles, or asserted that he had miraculous power...

Our intelligence is the aggregate intelligence of the cells which make us up. There is no soul, distinct from mind, and what we speak of as the mind is just the aggregate intelligence of cells. It is fallacious to declare that we have souls apart from animal intelligence, apart from brains. It is the brain that keeps us going. There is nothing beyond that.

Life goes on endlessly, but no more in human beings than in other animals,

The people heard it, and approved the doctrine, and immediately practiced the contrary.

He had a theory that musicians are incredibly complex, and know far less than other artists what they want and what they are; that they puzzle themselves as well as their friends; that their psychology is a modern development, and has not yet been understood.

Most areas of intellectual life have discovered the virtues of speculation, and have embraced them wildly. In academia, speculation is usually dignified as theory.
