In this service, each is to exert _himself_--employ _his own_ powers, lay out his own resources, improve his own opportunities.

A division of labor is the natural result.

One is remarkable for his intellectual endowments and acquisitions; another, for his wealth; and a third, for power and skill in using his muscles.

Such attributes, endlessly varied and diversified, proceed from the basis of a _common character_, by virtue of which all men and each--one as truly as another--are entitled, as a birth-right, to "life, liberty, and the pursuit of happiness." Each and all, one as well as another, may choose his own modes of contributing his share to the general welfare, in which his own is involved and identified.

Under one great law of mutual dependence and mutual responsibility, all are placed--the strong as well as the weak, the rich as much as the poor, the learned no less than the unlearned.
