The means which nature employs to bring about this development of all the capacities implanted in men is their mutual antagonism in society—what Kant calls the “unsocial sociableness of men, that is to say, their inclination to enter into society, an inclination which yet is bound up at every point with a resistance which threatens continually to break up the society so formed.” (Proposition 4.) Man hates society, and yet there alone he can develop his capacities; he cannot live there peaceably, and yet cannot live without it. It is the resistance which others offer to his inclinations and will—which he, on his part, shows likewise to the desires of others—that awakens all the latent powers of his nature and the determination to conquer his natural propensity to indolence and love of material comfort and to struggle for the first place among his fellow-creatures, to satisfy, in outstripping them, his love of glory and possession and power. “Without those, in themselves by no means lovely, qualities which set man in social opposition to man, so that each finds his selfish claims resisted by the selfishness of all the others, men would have lived on in an Arcadian shepherd life, in perfect harmony, contentment, and mutual love; but all their talents would forever have remained hidden and undeveloped. Thus, kindly as the sheep they tended, they would scarcely have given to their existence a greater value than that of their cattle. And the place among the ends of creation which was left for the development of rational beings would not have been filled. Thanks be to nature for the unsociableness, for the spiteful competition of vanity, for the insatiate desires of gain and power! Without these, all the excellent natural capacities of humanity would have slumbered undeveloped. Man’s will is for harmony; but nature knows better what is good for his species: her will is for dissension. He would like a life of comfort and satisfaction, but nature wills that he should be dragged out of idleness and inactive content and plunged into labour and trouble, in order that he may be made to seek in his own prudence for the means of again delivering himself from them. The natural impulses which prompt this effort,—the causes of unsociableness and mutual conflict, out of which so many evils spring,—are also in turn the spurs which drive him to the development of his powers. Thus, they really betray the providence of a wise Creator, and not the interference of some evil spirit which has meddled with the world which God has nobly planned, and enviously overturned its order.” (Proposition 4: Caird’s translation in _The Critical Philosophy of Kant_, Vol. II., pp. 550, 551.)
