The mind, in proportion as it is cut off from free communication with nature, with revelation, with God, with itself, loses its life, just as the body droops when debarred from the air and the cheering light from heaven.
Every mind was made for growth, for knowledge, and its nature is sinned against when it is doomed to ignorance.
Another powerful principle of our nature, which is the spring of war, is the passion for superiority, for triumph, for power. The human mind is aspiring, impatient of inferiority, and eager for preeminence and control.
I have chosen for the subject of this lecture Self-culture, or the care which every man owes to himself, to the unfolding and perfecting of his nature.
