To the truly ethical man, all of life is sacred, including forms of life that from the human point of view may seem lower than ours.

We need a boundless ethic, one which will include the animals, too. Until we extend the circle of his compassions to all living things, we will not find peace.

No one may shut his eyes to think the pain, which is therefore not visible to him, is non-existent.

In the hopes of reaching the moon men fail to see the flowers that blossom at their feet.

Today it is considered as exaggeration to proclaim constant respect for every form of life as being the serious demand of a rational ethic. But the time is coming when people will be amazed that the human race existed so long before it recognized that thoughtless injury to life is incompatible with real ethics. Ethics is in its unqualified form extended responsibility to everything that has life.

Ethics is in its unqualified form extended responsibility with regard to everything that has life.

Let us rejoice in the truth, wherever we find its lamp burning.
