Belief means not wanting to know what is true.

Belief consists in accepting the affirmations of the soul; unbelief, in denying them.

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.

To believe is to know that one believes, and to know that one believes is no longer to believe.

Belief is the result of the proportion, whatever it he, in which the many elements which go to make the human being are combined. In some the grosser nature preponderates; they believe largely in their stomachs, in the comforts and conveniences of life, and being of such kind, so long as these are not threatened, they gravitate steadily towards the earth. Numerically this is the largest class of believers, with very various denominations indeed; bearing the names of every faith beneath the sky, and composing the conservative elements in them, and therefore commonly persons of much weight in established systems. But they are what I have called them: their hearts are where I said they were, and as such interests are commonly selfish, and self separates instead of unites, they are not generally powerful against any heavy trial. Others of keener susceptibility are yet volatile, with slight power of continuance, and fly from attraction to attraction in the current of novelty. Others of stronger temper gravitate more slowly, but combine more firmly, and only disunite again when the idea or soul of the body into which they form dies out, or they fall under the influence of some very attractive force indeed. It may be doubted, indeed, whether a body which is really organised by a living idea can lose a healthy member except by violence.

At the core of all well-founded belief lies belief that is unfounded.

253. At the core of all well-founded belief, lies belief that is unfounded.

Belief is not a merely intellectual process, belief is not a mere persuasion of the mind, belief is something that is in our heart, and what you believe, you must do, because belief is from God. It is to the heart that God speaks, it is in the heart that God resides.... Here is a work that you have undertaken, a work so gigantic, so stupendous, the means for which are so poor, the resistance to which will be so strong, so organised ... and what means have you with which to carry out this tremendous work of yours? If you look at it intellectually, it is hopeless.... This intellectual process, if it is used honestly, if it is followed to the very end, leads you to despair. It leads you to death.

Belief is in ignorance. If you know, you know. And it is good that if you don’t know, know that you don’t know — the belief can deceive you. The belief can create an atmosphere in your mind, where, without knowing, you start thinking that you know. Belief is not trust, and the more strongly you say that you believe totally, the more you are afraid of the doubt within you.

At the foundation of well-founded belief lies belief that is not founded.

[U]ncomprimising belief carries much more weight than some special philosophical notions... [T]he great majority... can scarcely have any well-founded judgement concerning the correctness of certain important general ideas or doctrines. ...[T]he word "belief" can for this majority not mean "perceiving the truth of something" but... only... as "taking this as the basis for life." ...[T]his second kind of belief is much firmer... much more fixed... it can persist even against immediate contradicting experience... not... shaken by added scientific knowledge... sometimes... to the point where it seems completely absurd, and ends... only with the death of the believer. Science and history can teach us that this... may become a great danger... [S]uch belief has always belonged to the great forces in human history.

Belief, that sacred faculty which prompts the decisions of our will, and knits into harmonious working all the compacted energies of our being, is ours not for ourselves but for humanity. It is rightly used on truths which have been established by long experience and waiting toil, and which have stood in the fierce light of free and fearless questioning. Then it helps to bind men together, and to strengthen and direct their common action. It is desecrated when given to unproved and unquestioned statements, for the solace and private pleasure of the believer; to add a tinsel splendour to the plain straight road of our life and display a bright mirage beyond it; or even to drown the common sorrows of our kind by a self-deception which allows them not only to cast down, but also to degrade us. Whoso would deserve well of his fellows in this matter will guard the purity of his beliefs with a very fanaticism of jealous care, lest at any time it should rest on an unworthy object, and catch a stain which can never be wiped away. It is not only the leader of men, statesmen, philosopher, or poet, that owes this bounden duty to mankind. Every rustic who delivers in the village alehouse his slow, infrequent sentences, may help to kill or keep alive the fatal superstitions which clog his race. Every hard-worked wife of an artisan may transmit to her children beliefs which shall knit society together, or rend it in pieces. No simplicity of mind, no obscurity of station, can escape the universal duty of questioning all that we believe. It is true that this duty is a hard one, and the doubt which comes out of it is often a very bitter thing. It leaves us bare and powerless where we thought that we were safe and strong. To know all about anything is to know how to deal with it under all circumstances. We feel much happier and more secure when we think we know precisely what to do, no matter what happens, than when we have lost our way and do not know where to turn. And if we have supposed ourselves to know all about anything, and to be capable of doing what is fit in regard to it, we naturally do not like to find that we are really ignorant and powerless, that we have to begin again at the beginning, and try to learn what the thing is and how it is to be dealt with — if indeed anything can be learnt about it. It is the sense of power attached to a sense of knowledge that makes men desirous of believing, and afraid of doubting.

Not believing has a sickness which is believing a little.

He who knows the world to be bounded by a truth that contradicts it; he who knows himself to be bounded by a will that contradicts him; he who, knowing too well that he must be satisfied to live with this contradition and not attempt to escape from it, finds it hard to kick against the pricks; he who finally makes open confession of the contradition and determines to base his life upon it — he it is that believes. The believer is the man who puts his trust in God, in God Himself, and in God alone.
