“Ethics is in its unqualified form extended responsibility to everything that has life.”
Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
Context: It is the fate of every truth to be an object of ridicule when it is first acclaimed. It was once considered foolish to suppose that black men were really human beings and ought to be treated as such. What was once foolish has now become a recognized truth. 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.

"Exploring The Religious Naturalist Option", 13.7: Cosmos & Culture (23 November 2014) http://www.npr.org/blogs/13.7/2014/11/23/366104014/exploring-the-religious-naturalist-option
Context: Scientific inquiry has provisioned us with a mind-boggling new core narrative — the epic of evolution, the epic of creation, the universe story, big history, everybody's story — where humans and human cultures are understood to be emergent from and, hence, a part of nature.
Naturalists adopt this account as their core narrative, with full recognition that these understandings will certainly deepen and may shift with further scientific inquiry. They adopt the story currently on offer and do not simply select features of the story that support preferred theories of nature. … A religious naturalist is a naturalist who has adopted the epic as a core narrative and goes on to explore its religious potential, developing interpretive, spiritual and moral/ethical responses to the story.
Importantly, these responses are not front-loaded into the story as they are in the traditions. Therefore, the religious naturalist engages in a process, both individually and in the company of fellow explorers, to discover and experience them. These explorations are informed and guided by the mindful understandings inherent in our human traditions, including art, literature, philosophy and the religions of the world.

Games for Actors and non-Actors (1992)
Context: In truth the Theatre of the Oppressed has no end, because everything which happens in it must extend into life…. The Theatre of the Oppressed is located precisely on the frontier between fiction and reality – and this border must be crossed. If the show starts in fiction, its objective is to become integrated into reality, into life. Now in 1992, when so many certainties have become so many doubts, when so many dreams have withered on exposure to sunlight, and so many hopes have become as many deceptions – now that we are living through times and situations of great perplexity, full of doubts and uncertainties, now more than ever I believe it is time for a theatre which, at its best, will ask the right questions at the right times. Let us be democratic and ask our audiences to tell us their desires, and let us show them alternatives. Let us hope that one day – please, not too far in the future – we’ll be able to convince or force our governments, our leaders, to do the same; to ask their audiences – us – what they should do, so as to make this world a place to live and be happy in – yes, it is possible – rather than just a vast market in which we sell our goods and our souls. Let’s hope. Let’s work for it!
