A little reflection will show us that every belief, even the simplest and most fundamental, goes beyond experience when regarded as a guide to our actions.
No simplicity of mind, no obscurity of station, can escape the universal duty of questioning all that we believe.
Namely, we have no right to believe a thing true because everybody says so unless there are good grounds for believing that some one person at least has the means of knowing what is true, and is speaking the truth so far as he knows it.
It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.
Into this, for good or ill, is woven every belief of every man who has speech of his fellows. A awful privilege, and an awful responsibility, that we should help to create the world in which posterity will live.
In like manner, if I let myself believe anything on insufficient evidence, there may be no great harm done by the mere belief; it may be true after all, or I may never have occasion to exhibit it in outward acts.
If I steal money from any person, there may be no harm done from the mere transfer of possession; he may not feel the loss, or it may prevent him from using the money badly. But I cannot help doing this great wrong towards Man, that I make myself dishonest.
If a belief is not realized immediately in open deeds, it is stored up for the guidance of the future.
He who truly believes that which prompts him to an action has looked upon the action to lust after it, he has committed it already in his heart.
An atmosphere of beliefs and conceptions has been formed by the labours and struggles of our forefathers, which enables us to breathe amid the various and complex circumstances of our life.
Nor is it that truly a belief at all which has not some influence upon the actions of him who holds it.
We may always depend on it that algebra, which cannot be translated into good English and sound common sense, is bad algebra.
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.
To know all about anything is to know how to deal with it under all circumstances.
When an action is once done, it is right or wrong for ever; no accidental failure of its good or evil fruits can possibly alter that.
