Chapman Cohen, in his "Theism or Atheism," clearly states: "We know that man does not discover God, he invents him, and an invention is properly discarded when a better instrument is forthcoming. To-day, the hypothesis of God stands in just the same relation to the better life of to-day as the fire drill of the savage does to the modern method of obtaining a light. The belief in God may continue awhile in virtue of the lack of intelligence of some, of the carelessness of others, and of the conservative character of the mass. But no amount of apologizing can make up for the absence of genuine knowledge, nor can the flow of the finest eloquence do aught but clothe in regal raiment the body of a corpse."
Religion arose as a means of explanation of natural phenomena at a time when no other explanation of the origin of natural phenomena had been ascertained. God is always what Spinoza called it, "the asylum of ignorance. “When causes are unknown, God is brought forward; when causes are known, God retires into the background. In an age of ignorance, God is active; in an age of science, he is impotent. History attests this fact.
