making men less shallow and morally better by making them think. O–219 - Albert Schweitzer

The ethic of Reverence for Life is the ethic of Love widened into universality.

I do not believe that we can put into anyone ideas which are not in him
already. As a rule there is in everyone all sorts of good ideas, ready
like tinder. But much of this tinder catches fire, or catches it
successfully, only when it meets some flame or spark from the outside,
from some other person. Often, too, our own light goes out, and is
rekindled by some experience we go through with a fellow man. Thus we
have each of us cause to think with deep gratitude of those who have
lighted the flame within us. If we had before us those who have thus
been a blessing to us, and could tell them how it came about, they would
be amazed to learn what passed over from their life to ours.

It's not enough merely to exist. Every man has to seek in his own way to make his own self more noble and to relize his own true worth.
