Excerpt from Medical Inquiries and Observations, Vol. 2 of 4Of the moral faculty, and the understanding to be the seat of the conscience. The mysterious na ture of the union of those two moral principles with the will and understanding, is a subject foreign to the business of the present inquiry.As I consider virtue and vice to consist in action, and not in opinion, and as this action has its seat in the will, and not in the conscience, I shall confine my inquiries chie¿y to the in¿uence of physical causes upon that moral power of the mind, which is connected with volition, although many of these causes act likewise upon the conscience, as I shall Show hereafter. The state Of the moral faculty is visible in actions, which affect the well-being of society. The state Of the conscience is invisible, and therefore removed beyond our investigation.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
