Albert Schweitzer himself:
“Ethics are complete, profound, and alive only when addressed to all living beings. Only then we are in spiritual connection with the world … Profound love demands a deep conception and out of this develops reverence for the mystery of life. It brings us close to all beings. To the poorest and smallest, as well as all others. We reject the idea that man is ‘master of other creatures,’ ‘lord’ above all others. We bow to reality. We recognize that all existence is a mystery, like our own existence. The poor fly which we would like to kill with our hand has come into existence like ourselves. It knows anxiety, it knows hope for happiness, it knows fear of not existing any more. Has any man so far been able to create a fly? That is why our neighbor is not only man: my neighbor is a creature like myself, subject to the same joys, the same fears, and the idea of reverence for life gives us something more profound and mightier than the idea of humanism. It includes all living beings” (Quoted in The Schweitzer Album, edited by Erica Anderson, 1965, p. 174).
We are all Interconnected even with the Universe
