“Our god,” said the original natives of California to those who asked in what god they believed, “our god has neither father nor mother, and his origin is quite unknown. But he is present everywhere, he sees everything even at midnight, though himself invisible to human eyes. He is the friend of all good people, and he punishes the evil-doers.”

A Blackfoot Indian, when arguing with a Christian missionary, said: “There were two religions given by the Great Spirit, one in a book for the guidance of the white men, who, by following its teaching, will reach the white man’s heaven; the other is in the heads of the Indians, in the sky, rocks, rivers and mountains. And the red men who listen to God in nature, will hear his voice, and find at last the heaven beyond.”

These Indians consider that that external nature which to us is at the same time the veil and the revelation of the Divine, is sufficient to teach them so much concerning the Supreme Being that missionaries are superfluous.

Amongst those whose thoughts are occupied by the origin of religious perception in man, there exist several theories; the first, that the idea of infinity is a necessity to the mind of man, and that by enlarging the boundaries of space and of time, it arrives at that which is without space and without time. Thus may a true philosopher reason; but primitive man was no philosopher, and the infinite of philosophy had no existence for him. Another theory is that man is naturally endowed with religious instincts, which render him—alone of all living creatures—capable of perceiving the infinite in the invisible; but the nature of this innate instinct not being clearly defined, it is in vain that we try to explain one mystery by another. Others again affirm that religious impressions were the result of a supernatural revelation, but they seem vague with regard to the time in the life of humanity, to which people, and in what manner this came to pass. At the same time they draw attention to the fact that men have always arrived at conclusions rapidly, and, as they consider, without due reflection; one of these conclusions is that God is. Let us, for the sake of argument, replace the word man by the word intuitive sense or apprehension, and we shall understand why this intuitive sense renders it a superfluous task to make great researches as to the reasons of man’s decision that God is. This intuitive sense is wise, and utters at times great truths; but the philosophers who consider it their metier to seek for the reason of things are not content with what satisfies intuitive sense, and they act on their right.

In our days the religious problem is viewed from two sides. What is understood by these words—the conception of God? This is the question of questions; and the names of the writers on the subject, both philosophical and theological, are too numerous to give. It is a psychological and thought impelling study.

How did the idea of God first arise in the minds of primitive man? This is another question which few try and answer. It is a historical study.

This presentation of the problem is perhaps not calculated to inspire excitement or let loose agitating passions; and apparently the end of the nineteenth century will not witness the renewal of the philosophical debates on the subject which characterised the last half of the eighteenth.

Never either, before or since, has there been so much agitation, nor have men’s minds been so tossed by diverse currents. Many various theories were promulgated at the time, but opinions grouped themselves chiefly round two diametrically opposite schools of thought, towards one or the other of which they leaned.

According to Hume, Condillac and their adherents, matter alone exists; our understanding, our feelings, our will are only transformed sensations. This was pure materialism. Pure idealism was represented by Berkeley, who went so far as to deny the reality of matter; according to him the bodies making up the universe have no real existence; the true realities were God and the ideas He produced in us.

Those who preserved their ancient beliefs were the most troubled, they began to ask themselves whether the foundations of their faith were solid, and they much desired to see certain problems solved. These thoughts had exercised the minds of the sages of India, the thinkers of Greece, the dreamers of Alexandria, and the divines and scholars of the Middle Ages. They were the old problems of the world, what we know of the Infinite, the questions of the beginning and end of our existence; the questions of the possibility of absolute certainty in the evidence of the senses, of reason or of faith.
