The eloquence of those who led the underpaid and half-starved workers could no longer, for me, at least, ring with conviction. Something more than the purely economic interpretation was involved. The bitter struggle for bread, for a home and material comfort, was but one phase of the problem. There was another phase, perhaps even more fundamental, that had been absolutely neglected by the adherents of the new dogmas. That other phase was the driving power of instinct, a power uncontrolled and unnoticed. The great fundamental instinct of sex was expressing itself in these ever-growing broods, in the prosperity of the slum midwife and her colleague the slum undertaker. In spite of all my sympathy with the dream of liberated Labor, I was driven to ask whether this urging power of sex, this deep instinct, was not at least partially responsible, along with industrial injustice, for the widespread misery of the world. To find an answer to this problem which at that point in my experience I could not solve, I determined to study conditions in Europe. Perhaps there I might discover a new approach, a great illumination. Just before the outbreak of the war, I visited France, Spain, Germany and Great Britain. Everywhere I found the same dogmas and prejudices among labor leaders, the same intense but limited vision, the same insistence upon the purely economic phases of human nature, the same belief that if the problem of hunger were solved, the question of the women and children would take care of itself. In this attitude I discovered, then, what seemed to me to be purely masculine reasoning; and because it was purely masculine, it could at best be but half true. Feminine insight must be brought to bear on all questions; and here, it struck me, the fallacy of the masculine, the all-too-masculine, was brutally exposed. I was encouraged and strengthened in this attitude by the support of certain leaders who had studied human nature and who had reached the same conclusion: that civilization could not solve the problem of Hunger until it recognized the titanic strength of the sexual instinct. In Spain, I found that Lorenzo Portet, who was carrying on the work of the martyred Francisco Ferrer, had reached this same conclusion. In Italy, Enrico Malatesta, the valiant leader who was after the war to play so dramatic a role, was likewise combating the current dogma of the orthodox Socialists. In Berlin, Rudolph Rocker was engaged in the thankless task of puncturing the articles of faith of the orthodox Marxian religion. It is quite needless to add that these men who had probed beneath the surface of the problem and had diagnosed so much more completely the complex malady of contemporary society were intensely disliked by the superficial theorists of the neo-Marxian School.
