Much confusion has been caused, and much atheism generated, by the very limited knowledge and very large ignorance of many expounders of popular religion and spiritualistic cults. They teach that the human being, after a first short appearance on this planet for an insignificant period (for what is seventy years or so against the millions of years which geology proclaims as its history?) will pass into a post-mortem state wherein it will dwell forever, that is, for all eternity. That the little ego with all its attributes and qualities, will keep the personal identity and the personal existence of that brief appearance on earth unchanged, congealed into permanency, outliving the earth itself, reunited with family and friends, finding itself among primitive people of the Iron Age and among the cave-dwellers, is a ridiculous notion. It is so utterly unscientific an idea, so appallingly opposed to real religion, as to be ludicrous.
