Self-preservation, nature's first great law, all the creatures, except man, doth awe.

Self-preservation is the first law of nature.

There is not in nature, a thing that makes man so deformed, so beastly, as doth intemperate anger.

Training was one thing, reality another, and no one could be sure that the ancient human instincts of self-preservation would not take over in an emergency.

The first law of nature is self-preservation. Cut off that which may harm you. But if it is worth preserving, and is meaningful, nourish it and have no regrets. Ultimately, this is true living and love of self...from within.

Me avergüenza sentir miedo, incluso en sueños, porque eso me revela que aún deseo estar vivo. El instinto de supervivencia es lo más humillante de todo.
