Had I time, I should be glad to speak of other great ideas belonging to the science of mind, and which sum up and give us, in one bright expression, the speculations of ages. The idea of human life, of its true end and greatness; the idea of virtue, as the absolute and ultimate good; the idea of liberty, which is the highest thought of political science, and which, by its intimate presence to the minds of the people, is the chief spring of our country's life and greatness,--all these might be enlarged on; and I might show how these may be awakened in the laborer, and may give him an elevation which many who are above labor want. But, leaving all these, I will only refer to another, one of the most important results of the science of mind, and which the laborer, in common with every man, may and should receive, and should strengthen by patient thought. It is the idea of his importance as an individual. He is to understand that he has a value, not as belonging to a community, and contributing to a general good which is distinct from himself, but on his own account. He is not a mere part of a machine. In a machine the parts are useless, but as conducing to the end of the whole, for which alone they subsist. Not so a man. He is not simply a means, but an end, and exists for his own sake, for the unfolding of his nature, for his own virtue and happiness. True, he is to work for others, but not servilely, not with a broken spirit, not so as to degrade himself: he is to work for others from a wise self-regard, from principles of justice and benevolence, and in the exercise of a free will and intelligence, by which his own character is perfected. His individual dignity, not derived from birth, from success, from wealth, from outward show, but consisting in the indestructible principles of his soul,--this ought to enter into his habitual consciousness. I do not speak rhetorically or use the cant of rhapsodists, but I utter my calm, deliberate conviction, when I say that the laborer ought to regard himself with a self-respect unknown to the proudest monarch who rests on outward rank.
