"We have all learned to become sensitive to the physical environment. We know that we depend upon it, that it is fragile, and that we have the power to ruin it, thereby ruining our own lives, or more probably those of our descendants. Perhaps fewer of us are sensitive to what we might call the moral or ethical environment. This is the surrounding climate of ideas about how to live. It determines what we find acceptable or unacceptable, admirable or contemptible. It determines our conceptions of when things are going well and when they are going badly. It determines our conception of what is due to us, and what is due from us, as we relate to others. It shapes our emotional responses, determining what is a cause of pride or shame, or anger or gratitude, or what can be forgiven and what cannot. It gives us our standards — our standards of behaviour. In the eyes of some thinkers, most famously perhaps Hegel, it shapes our very identities. Our consciousness of ourselves is largely or even essentially a consciousness of how we stand for other people."
