Context: In the greatest confusion there is still an open channel to the soul. It may be difficult to find because by midlife it is overgrown, and some of the wildest thickets that surround it grow out of what we describe as our education. But the channel is always there, and it is our business to keep it open, to have access to the deepest part of ourselves—to that part of us which is conscious. … The independence of this consciousness, which has the strength to be immune to the noise of history and the distractions of our immediate surroundings, is what the life struggle is all about. The soul has to find and hold its ground against hostile forces, sometimes embodied in ideas which frequently deny its very existence, and which indeed often seem to be trying to annul it altogether.
