The love for all living creatures is the most noble attribute of man. Charles Darwin
Our task must be to free ourselves by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. Albert Einstein
So is man's heart. The desire to perform a work which will endure, which will survive him, is the origin of his superiority over all other living creatures here below. It is this which has established his dominion, and this it is which justifies it, over all the world. Jules Verne
As the births of living creatures are at first ill-shapen, so are all innovations, which are the births of time. Francis Bacon
Thus the sum of things is ever being reviewed, and mortals dependent one upon another. Some nations increase, others diminish, and in a short space the generations of living creatures are changed and like runners pass on the torch of life. Lucretius
The Prophets even express their surprise that God should take notice of man, who is too little and too unimportant to be worthy of the attention of the Creator; how, then, should other living creatures be considered as proper objects for Divine Providence! Maimonides
