…our care for the world we inhabit is not simply a duty laid upon us but a dimension of life made whole: a redeeming activity grounded in the character of our own redemption, a revelation of the true ‘face’ of creation as we ourselves undergo the uncovering of our own human face before God. Going back to the root meaning of the Hebrew word, what we’re asked to undertake is in fact a conversion – a turning – towards the truth: towards the God who is eternally active and giving in ways beyond our concepts, towards the hidden depths of who we ourselves are – and thus towards the face of the earth, seeing it freshly in its unfathomable interrelatedness.
Rowan Williams, ‘Renewing the Face of the Earth: Human Responsibility and the Environment’, http://www.archbishopofcanterbury.org/2351

“A human being is a part of a whole, called by us “universe”, a part limited in time and space He experiences himself, his thoughts and feelings as something separated from the rest…a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our talk must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.” Einstein
