"We are able to discern not only what we already are, but what we may become, to see in ourselves germs and promises of a growth to which no bounds can be set, to dart beyond what we have actually gained to the idea of perfection as the end of our being. It is by this self-comprehending power that we are distinguished from the brutes, which give no signs of looking into themselves. Without this there would be no self-culture, for we should not know the work to be done; and one reason why self-culture is so little proposed is, that so few penetrate into their own nature. To most men, their own spirits are shadowy, unreal, compared with what is outward. When they happen to cast a glance inward, they see there only a dark, vague chaos. They distinguish, perhaps, some violent passion, which has driven them to injurious excess; but their highest powers hardly attract a thought; and thus multitudes live and die as truly strangers to themselves as to countries of which they have heard the name, but which human foot has never trodden."
