n were to become by thy
will a universal law of nature." "So act as to treat humanity, whether
in thine own person or in that of another, in every case as an end,
never as a means only." Or as Professor Royce puts the same thought;
"Act as a being would act who included thy will and thy neighbor's will
in the unity of one life, and who had therefore to suffer the
consequences for the aims of both that will follow from the act of
either." "In so far as in thee lies, act as if thou wert at once thy
neighbor and thyself. Treat these two lives as one."

+The realization of the good of all in and through the act of each is
the social ideal.+--In everyday matters this can be brought about by
simply taking account of all the interests of others which will be
affected by our act. In the relations between employer and employee, for
instance, profit sharing is the most practical form of realizing this
community of interest. Such action involves a co-operation of interests
as the motives of the individual act.

The larger social ends, such as education, philanthropy, reform, public
improvements, require the co-operation of many individuals in the same
enterprise. The readiness to contribute a fair share of our time, money,
and influence to these larger public interests, which no individual can
undertake alone, is an important part of our social duty. Every
beneficent cause, every effort to rouse public sentiment against a
wrong, or to make it effective in the enforcement of a right; every
endeavor to unite men in social intercourse; every plan to extend the
opportunities for education; every measure for the relief of the
deserving poor, and the protection of homeless children; every wise
movement for the prevention of vice, crime, and intemperance, is
entitled to receive from each one of us the same intelligent attention,
the same keenness of interest, the same energy of devotion, the same
sacrifice of inclination and convenience, the same resoluteness and
courage of action that we give to our private affairs.

+Co-operation, then, is of two kinds, inward and outward: co-operation
between the interests of others and of ourselves in the motive to our
individual action; and co-operation of our action with the action of
others to accomplish objects too vast for private undertaking.+--Both
forms of co-operation are in principle the same; they strengthen and
support each other. The man who is in the habit of considering the
interest
