“A human being is part of a whole, called by us the Universe, a part limited in time and space. [We experience ourselves, our] thoughts and feelings, as something separated from the rest — a kind of optical delusion of [our] consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us [excluding others, including animals]. Our task must be to free ourselves from this prison by widening our circles of compassion to embrace all living creatures and the whole of nature in its beauty.”

– Albert Einstein
