We are conscious of an animal in us, which awakens in proportion as our higher nature slumbers. It is reptile and sensual, and perhaps cannot be wholly expelled; like the worms which, even in life and health, occupy our bodies. Possibly we may withdraw from it, but never change its nature. I fear that it may enjoy a certain health of its own; that we may be well, yet not pure.
Henry David ThoreauIt is not that we love to be alone, but that we love to soar, and when we do soar, the company grows thinner and thinner until there is none at all. …We are not the less to aim at the summits though the multitude does not ascend them.
Henry David Thoreau
