“Once a man recognizes himself as a being surrounded by other beings in this world and begins to respect his life and take it to the highest value, he becomes a thinking being. Then he values other lives and experiences them as part of his own life. With that, his goal is to help everyone take their life to the highest value; anything which limits or destroys a life is evil. That is morality. That is how men are related to the world around them.”
“The quiet conscience is an invention of the devil.”
“A man who possesses a veneration of life will not simply say his prayers. He will throw himself into the battle to preserve life, if for no other reason than that he himself is an extension of life around him.”
“A thinking man feels compelled to approach all life with the same reverence he has for his own.”
“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.”
“We need a boundless ethics which will include animals also.”
“The great fault of all ethics hitherto has been that they believed themselves to have to deal only with the relations of man to man. In reality, however, the question is what is his attitude to the world and all life that comes within his reach.”
“By respect for life we become religious in a way that is elementary, profound and alive.”
“We cannot abdicate our conscience to an organization, nor to a government. 'Am I my brother's keeper?' Most certainly I am! I cannot escape my responsibility by saying the State will do all that is necessary. It is a tragedy that nowadays so many think and feel otherwise.”
“Where principles and heart stand in conflict with each other, let us make the law of the spirit free from the law of principles.”
