George Wald

You see, every creature alive on the earth today represents an unbroken line of life that stretches back to the first primitive organism to appear on this planet; and that is about three billion years.

Socialism has no moral justification whatsoever; poor people are not morally superior to rich people, nor are they owed anything by rich people simply because of their lack of success. Charity is not a socialist concept - it is a religious one, an acknowledgment of God's sovereignty over property, a sovereignty the Left utterly rejects.
