No judgment can be just or wise, but that which is built on the conviction of the paramount worth and importance of duty. This is the fundamental truth, the supreme law of reason; and the mind which does not start from this, in its inquiries into human affairs, is doomed to great, perhaps fatal error. The right is the supreme good, and includes all other goods. In seeking and adhering to it, we secure our true and only happiness. All prosperity, not founded on it, is built on sand.
