Thought cannot avoid the ethical or reverence and love for all life.
It will abandon the old confined systems of ethics
and be forced to recognize the ethics that knows no bounds.
But on the other hand,
those who believe in love for all creation
must realize clearly the difficulties involved
in the problem of a boundless ethic
and must be resolved not to veil from [humankind]
the conflicts which this ethic will involve [us],
but allow [us] really to experience them.
To think out in every implication the ethic of love for all creation
-- this is the difficult task which confronts our age.

Albert Schweitzer
