Some savages are drawn away here or there, but that is all. The greater faiths and forms of faith, Catholicism, Lutheranism, the Greek Church, Mahommedanism, Buddhism, Hinduism, and many others, remain as they were. Their believers are neither converted nor convert. Men born into them remain as they were born. They do not change, they are satisfied with what they have.

They are more than satisfied; they are often, almost always, passionately attached to their faith.

There is nothing men value more than their religion. There is nothing so unbearable to them as an attack upon it. No one will allow it. Even the savage clings to his fetish in the mountain top and will not permit of insult to it. Men will brave all kinds of disaster and death rather than deny their faith, that which their fathers believed. It is to all their highest possession. The Catholic, the Chinese ancestor worshipper, the Hindu, the Calvinist, the Buddhist, the Jew—their names are too numerous to mention—none yields to any other in this. It is true of all faiths. No one faith has any monopoly of this enthusiasm. It is common to all.

But wherein lies the spell that religion has cast upon the souls of men? The influence is the same. What is the secret of it?

Can it be that there is some secret common to all religions, some belief, some doctrine that is the cause of this? If so, what is it? If there is such a common secret, why is it so hidden?

For hidden it certainly is.

Nothing can be more certain than that no one religion recognises any such secret in the others. It is the very reverse. The more a man clings to his own religion the more he scorns all others. Far from acknowledging any common truth, he denounces all other faiths as mistaken, as untrue; nay, more, they are to him false, deliberately false; the enthusiast believes them wicked, the fanatic in his own faith calls all others devilish. The more a man loves his religion the more he abominates all others. A Christian would scorn the idea of the essence of his faith being common to all others, or any other. If there be any common truth it is a very secret truth.

Is there any secret truth? If so, what is it?

There is a further question.

There is probably no one thing that we learn with more certainty than this, that whatever exists, whatever persists, does so because it fulfils a want, because it's of use. It is immaterial where we look, the rule is absolute. In the material world Darwin and others have shewn it to us over and over again. When anything is useless it atrophies. So have the snake and the whale lost their legs, and man his hairy skin and sense of scent. Males have lost their power of suckling their young; with females this power has increased. Need developes any thing or any quality; when it becomes needless it dies. Where we find anything flourishing and persistent we are sure always that it is so because it is wanted, because it fills a need.
