That there exists such a power of self-regulation is a fact recognized in every department of social intercourse--in the attribution of praise or blame, in the teachings of the moralist, in the eye of the law, and in the process of education. Every individual is supposed to have a command over his own actions, except such as are purely automatic. It is not supposed that men are responsible for their congenital tastes or abilities; but all members of the community are held responsible for their actions towards other members of the community, and to a certain extent they are judged to be wise or foolish with regard to themselves, on the supposition that they are able to carry out a purposed conduct. And even if in various particulars it is seen that they do not possess such a power, they, or the persons responsible for their earlier education are blamed for their want of this power since it is held to be one of the most characteristic and valuable possessions of humanity. Thus we find the judicious parent, from the very first, endeavours to inculcate in the child habits of command over his temper and his appetites. The youth who has received the lessons of wise counsellers, who has been imbued with the lessons of Christianity, who has drunk in the teachings of the ancient moralists, and framed his ambitions upon the severe examples of early Greece and Rome, or who has found his sympathies excited by the dreams of modern philanthropy, knows that the foundation of all his personal greatness is in his power of self-command. It is no idle verbiage that of the rhetorician, the preacher, the philosophical novelist, the poet, when they exhort to the cultivation of the powers of the Will in their varied representations of the aspirations and struggles of noble humanity. There is something that calls forth the moralist's sympathies in the poet's appeals to the power of Will, and there is no grander spectacle in all this universe than to witness the battle of the will-power of a man against difficulties and oppositions of all sorts; none the less if the scene of the conflict be in the region of his own heart and mind, rather than in the wider field of the battle of life. The evolutionist is bound to account for this amongst the other phenomena of human existence. The principles of such an evolution are contained in Mr. Spencer's "Psychology," but the development is not elaborated in detail, and is well worthy of a special study. We have previously roughly indicated the outlines of such a study; and as the special psychological question has been treated in an interesting and suggestive manner by the Rev. T. W. Fowle in the number of the "Nineteenth Century" for March 1881, we will find it convenient to take this article as the text or basis of our own remarks.
