say the least, very doubtful. The truth is that a society and its members act and react in such wise that while, on the one hand, the nature of the society is determined by the natures of its members; on the other hand, the activities of its members (and presently their natures) are redetermined by the needs of the society, as these alter: change in either entails change in the other. It is an obvious implication that, to a great extent, the life of a society so sways the wills of its members as to turn them to its ends. That which is manifest during the militant stage, when the social aggregate coerces its units into co-operation for defence, and sacrifices many of their lives for its corporate preservation, holds under another form during the industrial stage, as we at present know it. Though the co-operation of citizens is now voluntary instead of compulsory; yet the social forces impel them to achieve social ends while apparently achieving only their own ends. The man who, carrying out an invention, thinks only of private welfare to be thereby secured, is in far larger measure working for public welfare: instance the contrast between the fortune made by Watt and the wealth which the steam-engine has given to mankind. He who utilizes a new material, improves a method of production, or introduces a better way of carrying on business, and does this for the purpose of distancing competitors, gains for himself little compared with that which he gains for the community by facilitating the lives of all. Either unknowingly or in spite of themselves, Nature leads men by purely personal motives to fulfil her ends: Nature being one of our expressions for the Ultimate Cause of things, and the end, remote when not proximate, being the highest form of human life.
