Remember, too, the mechanic of our modern world is [p.229] not the factory labourer alone. Wherever in social life, whether in political activity or in industrial management, in educational methods or in religious effort, there appears a man who appreciates the need first of observing natural conditions and finding natural laws, and then of acting only in accord with the suggestions of the laws discovered, just there is the mechanic, the responsible agent of a law-free but always lawful nature. The soldier as creature of this world was only a passive, wholly material part of a mechanism which depended for its movement upon some outside power or will; but the mechanic, be he humble labourer skilful in the use of tools, or political leader supporting no law that is not, so far as can be known, in accord with natural life, or religious reformer loyal to life as it is, shares positively in the activity that makes the machinery go and in whatever this activity produces. And yet one thing more must be said. Just as before we had to view free thought in the light of a divided labour, the individual sharing in it only as he treated his own peculiar experience as hypothetical, as a means to an end, not merely an end in itself, or as he was subject to the restraint and correction of the different experiences of others, so now we must recognize that effective activity, not less than true thinking or than realistic experience, is also necessarily the labour, never of one alone, but of many. The successful mechanic--in other words, the fully responsible agent of a law-free nature--is never an isolated creature with merely such a sentimental concern for his neighbours as might spring from the recognized chance [p.230] of meeting them in that world of the hereafter, where all are to be equal and where love and peace are to supplant the present hate and rivalry; he is, on the contrary, one among others, different from him, it is true, and often very positively at variance with him, but engaged with him in a single activity and achievement. His difference works not against, but with their differences for thoroughly controlled, truly effective activity. As things are real, though never final, so men, at work in the world, are individual and individually important, but never alone.
