One must state it plainly. Religion comes from the period of human prehistory where nobody — not even the mighty Democritus who concluded that all matter was made from atoms — had the smallest idea what was going on. It comes from the bawling and fearful infancy of our species, and is a babyish attempt to meet our inescapable demand for knowledge (as well as for comfort, reassurance and other infantile needs). Today the least educated of my children knows much more about the natural order than any of the founders of religion, and one would like to think — though the connection is not a fully demonstrable one — that this is why they seem so uninterested in sending fellow humans to hell.

The beginning of religion, more precisely its content, is the concept of religion itself, that God is the absolute truth, the truth of all things, and subjectively that religion alone is the absolutely true knowledge.

The origin of all religions -- Judaeo-Christianity included -- is to be found in a few primeval truths, not one of which can be explained apart from all the others, as each is a complement of the rest in some one detail. And they are all, more or less, broken rays of the same Sun of truth, and their beginnings have to be sought in the archaic records of the Wisdom-religion. Without the light of the latter, the greatest scholars can see but the skeletons thereof covered with masks of fancy

Religion began when the first scoundrel met the first fool.

Primitive religions consisted mainly in the worship of the powers of nature. ...the essential thing in religion was not morality, but the ceremonial method of placating the god, securing his gifts, and ascertaining his wishes. He might even be pleased best by immoral actions, by the immolation of human victims, by the sacrifice of woman's chastity, or by the burning of the first born.

As every enquiry, which regards religion, is of the utmost importance, there are two questions in particular, which challenge our attention, to wit, that concerning its foundation in reason, and that concerning its origin in human nature. Happily, the first question, which is the most important, admits of the most obvious, at least, the clearest, solution. The whole frame of nature bespeaks an intelligent author; and no rational enquirer can, after serious reflection, suspend his belief a moment with regard to the primary principles of genuine Theism and Religion. But the other question, concerning the origin of religion in human nature, is exposed to some more difficulty. The belief of invisible, intelligent power has been very generally diffused over the human race, in all places and in all ages; but it has neither perhaps been so universal as to admit of no exception, nor has it been, in any degree, uniform in the ideas, which it has suggested. Some nations have been discovered, who entertained no sentiments of Religion, if travellers and historians may be credited; and no two nations, and scarce any two men, have ever agreed precisely in the same sentiments.

The only religion that has not been invented, and that has in it every evidence of divine originality, is pure and simple deism. It must have been the first, and will probably be the last that man believes: but pure and simple deism does not answer the purpose of despotic governments. They cannot lay hold of religion as an engine, but by mixing it with human inventions, and making their own authority a part.

If there is one thing which a comparative study of religions places in the clearest light, it is the inevitable decay to which every religion is exposed. It may seem almost like a truism, that no religion can continue to be what it was during the lifetime of its founder and its first apostles. Yet it is but seldom borne in mind that without constant reformation, i.e. without a constant return to its fountan-head, every religion, even the most perfect, nay the most perfect on account of its very perfection, more even than others, suffers from its contact with the world, as the purest air suffers froln the mere fact of its being breathed. Whenever we can trace back a religion to its first beginnings, we find it free from many of the blemishes that offend us in its later phases. The founders of the ancient religions of the world, as far as we can judge, were minds of a high stamp, full of noble aspirations, yearning for truth, devoted to the welfare of their neighbors, examples of purity and unselfishness. What they desired to found upon earth was but seldom realized, and their sayings, if preserved in their original form, offer often a strange contrast to the practice of those who profess to be their disciples. As soon as a religion is established, and more particularly when it has become the religion of a powerful state, the foreign and worldly elements encroach more and more on the original foundation, and human interests mar the simplicity and purity of the plan which the founder had conceived in his own heart, and matured in his communings with his God. Even those who lived with Buddha misunderstood his words, and at the Great Council which had to settle the Buddhist canon, Asoka, the Indian Constantine had to remind the assembled priests that "what had been said by Buddha, that alone was well said;" and that certain works ascribed to Buddha, as, for instance, the instruction given to his son, Râhula, were apocryphal, if not heretical.

Religion has had a natural origin, like coal, and rock salt, and mountains, and river valleys, and everything else. It has been made in the laboratory of human feeling and imagination. The gods did not make men; men made the gods.

The Oxford Classical Dictionary firmly states: “No word in either Greek or Latin corresponds to the English ‘religion’ or ‘religious.’ ”6 The idea of religion as an essentially personal and systematic pursuit was entirely absent from classical Greece, Japan, Egypt, Mesopotamia, Iran, China, and India.7 Nor does the Hebrew Bible have any abstract concept of religion; and the Talmudic rabbis would have found it impossible to express what they meant by faith in a single word or even in a formula, since the Talmud was expressly designed to bring the whole of human life into the ambit of the sacred.8

Religion is a strictly human infirmity. No other animal has it. It originated far back in the past, when the human world was young and the mind just beginning to open. It is an anachronism today, with our science and understanding. It survives solely by the force of tradition.

Religion is partly fundamental & immutable partly circumstantial & mutable. The first was the Religion of Adam, Enoch, Noah, Abraham Moses Christ & all the saints & consists of two parts our duty towards God & our duty towards man or piety & righteousness, piety which I will here call Godliness & Humanity.

Religion was invented when the first con man met the first fool.

What we commonly have in our mind when we speak of religion is a definite set of doctrines, of a more or less metaphysical character, formulated in a creed and supported by an organization distinct from the state. And the first thing we have to learn about the is that it included nothing of the kind. There was no church, there was no creed, there were no articles. Priests there were, but they were merely public officials, appointed to perform certain religious rites. The distinction between cleric and layman, as we know it, did not exist; and whatever the religion of the Greeks may have been, one thing at any rate is clear, that it was something very different from all that we are in the habit of associating with the world.
