...the incredulity of mankind, who do not truly believe in anything new until they have had actual experience of it.

Science has not yet taught us if madness is or is not the sublimity of the intelligence.

"Because we cannot discover God's throne in the sky with a radiotelescope or establish (for certain) that a beloved father or mother is still about in a more or less corporeal form, people assume that such ideas are "not true." I would rather say that they are not "true" enough, for these are conceptions of a kind that have accompanied human life from prehistoric times, and that still break through into consciousness at any provocation.

Modern man may assert that he can dispose with them, and he may bolster his opinion by insisting that there is no scientific evidence of their truth. Or he may even regret the loss of his convictions. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no means of proving immortality), why should we bother about evidence? Even if we did not know by reason our need for salt in our food, we should nonetheless profit from its use. We might argue that the use of salt is a mere illusion of taste or a superstition; but it would still contribute to our well-being. Why, then, should we deprive ourselves of views that would prove helpful in crises and would give a meaning to our existence?

And how do we know that such ideas are not true? Many people would agree with me if I stated flatly that such ideas are probably illusions. What they fail to realize is that the denial is as impossible to "prove" as the assertion of religious belief. We are entirely free to choose which point of view we take; it will in any case be an arbitrary decision.

There is, however, a strong empirical reason why we should cultivate thoughts that can never be proved. It is that they are known to be useful. Man positively needs general ideas and convictions that will give a meaning to his life and enable him to find a place for himself in the universe. He can stand the most incredible hardships when he is convinced that they make sense; he is crushed when, on top of all his misfortunes, he has to admit t

There is no scientific explanation for consciousness yet it is.

The brute necessity of believing something so long as life lasts does not justify any belief in particular.

The interest I have to believe a thing is no proof that such a thing exists.

"So you truly do not believe in God?"
"I find no reason to, in nature... If the idea of God is unknown in the state of nature, it must then be a human invention."

the world we live in is very nearly incomprehensible to most of us. There is almost no fact, whether actual or imagined, that will surprise us for very long, since we have no comprehensive and consistent picture of the world that would make the fact appear as an unacceptable contradiction. We believe because there is no reason not to believe.

The question of belief is a curious one, partaking of the wonders of childhood and the blind hopefulness of the very old; in all the world there is not someone who does not believe something. It might be suggested, and not easily disproven that anything, no matter how exotic, can be believed by someone. On the other hand, abstract belief is largely impossible; it is the concrete, the actuality of the cup, the candle, the sacrificial stone, which hardens belief; the statue is nothing until it cries, the philosophy is nothing until the philosopher is martyred.

It is so many years before one can believe enough in what one feels even to know what the feeling is

It is almost impossible to state what one in fact believes, because it is almost impossible to hold a belief and to define it at the same time.

Nothing is so firmly believed as that which we least know.

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,

No one has figured out how accidental is the marriage of blasphemy and fate.
