The nineteenth century witnessed the birth and expansion of a great number of new stimulant reagents, the discoveries of physics and chemistry, which, with the climax of the World War of 1914-1918, have made for a more or less complete deliquescence of accepted religion. For the great majority there was no faith to take its place. War, pre-war, and post-war shocks have continued with their incessant pounding upon the reserves of energy. Under these conditions the adrenal personalities are bound to suffer. The other endocrine types suffer, too, but quite differently. Today, anti-adrenal, anti-religious ideas are epidemic. Of these, first prize belongs to a cult of egotism fathered by the Napoleonic Idea, consciously assertive and self-conscious in Max Stirner's "The Ego and His Own," which engendered a swarm of imitators and plagiarists. Human beings are all incorrigible egoists more or less, furtive or frank. But social and religious codes curbed the most narcissistic of kings and conquerors. Before Napoleon, all of them vowed allegiance and expressed submission to some sort of deity, confessed some fear of the Lord in their hearts. But the ideas of Napoleon flouted all that. The unscrupulous predatory who put effectual scheming for the self plainly above every other consideration and rode rough shod over all his fellows appealed powerfully to the latent animality of the adrenal types. Then came the dawning awareness of capital and labor of themselves as classes fiercely opposed forever in the policy of cut-throat versus cut-throat. The labor organizations and the commercial companies and corporations pitted themselves against each other consciously. Doctrines like "Property is but Robbery," "Everyone for himself and the devil take the hindmost," the "Iron Law of Wages" and the "Facts is Facts" of the Gradgrinds were the phrases of the nineteenth century that assisted. Finally came the Darwinian revelation of man as the ape-parvenu, which completed the disintegration of the old restraints. Man seemed to see himself now for the first time stark and naked. But Man consists of many varieties, and all reacted differently to the image in the clouded mirror. There was universal attempt at suppression. But slowly the anti-adrenal forces infiltrated every activity and every soul. Like a hidden focus of infection in the body, it germinated and poisoned. A slow fever crept into life. A febrile quality tinged the acquisition of wealth, the concentration upon sex, and the desperate pursuit of the novel stimulus.
