or less obnoxious prejudices on the subject of honour, glory, religion, patriotism, sacrifice, liberty, or love--or perhaps by some feeble, dreary poetical effusion. None the less, he will find himself affected by the general enthusiasm; and it will be necessary for him, almost at every instant, to pull himself violently together, to make startled appeal to every conviction within him, in order to convince himself that these partisans of hoary errors are wrong, notwithstanding their number, and that he, with his isolated reason, alone is right. 3 Indeed, when we consider the relation of man to matter, it is surprising to find how little light has yet been thrown upon it, how little has been definitely fixed. Elementary, imperious, as this relation undoubtedly is, humanity has always been wavering, uncertain, passing from the most dangerous confidence to the most systematic distrust, from adoration to horror, from asceticism and complete renouncement to their corresponding extremes. The days are past when an irrational, useless abstinence was preached, and put into practice--an abstinence often fully as harmful as habitual excess. We are entitled to all that helps to maintain, or advance, the development of the body; this is our right, but it has its limits; and these limits it would be well to define with the utmost exactness, for whatever may trespass beyond must infallibly weaken the growth of that other side of ourselves, the flower that the leaves round about it will either stifle or nourish. And humanity, that so long has been watching this flower, studying it so intently, noting its subtlest, most fleeting perfumes and shades, is most often content to abandon to the caprice of the temperament, be this evil or good, to the passing moment, or to chance, the government of the unconscious forces that will, like the leaves, be discreetly active, sustaining, life-giving, or profoundly selfish, destructive, and fatal. Hitherto, perhaps, this may have been done with impunity; for the ideal of mankind (which at the start was concerned with the body alone) wavered long between matter and spirit. To-day, however, it clings, with ever profounder conviction, to the human intelligence. We no longer strive to compete with the lion, the panther, the great anthropoid ape, in force or agility; in beauty with the flower or the shine of the stars on the sea. The utilisation by our intellect of every unconscious force, the gradual subjugation of matter and the search for its secret--these at present appear the most evident aim of our race, and its most probable mission. In the days of doubt there was no satisfaction, or even excess, but was excusable, and moral, so long as it wrought no irreparable loss of strength or actual organic harm. But now that the mission of the race is becoming more clearly defined, the duty is on us to leave on one side whatever is not directly helpful to the spiritual part of our being. Sterile pleasures
