Man is the only religious animal. In the Holy task of smoothing his brother's path to the happiness of heaven, he has turned the globe into a graveyard.
You have noticed that the human being is a curiosity. In times past he has had (and worn out and flung away) hundreds and hundreds of religions; today he has hundreds and hundreds of religions, and launches not fewer than three new ones every year. I could enlarge on that number and still be within the facts.
