To do this, the artifacts of civilization have to satisfy the laws of nature. They do NOT have to satisfy the imaginary requirements of human beings; however, "social responsibility" does require the satisfaction of moral standards that, also, are created in the imaginations of men and women. In the first instance, I am trying to point out the irrelevance of economical requirements; and, in the second instance, I am agreeing that the moral standards imagined by philosophers are important. The question is: "Are the moral standards that are now emerging a direct consequence of physical law?" However, while moral standards remain ungrounded, it is probably best to concentrate on physical sustainability. Clearly, "moral standards" that result in the extinction of life on Earth are not moral.Tom Wayburnhttps://www.blogger.com/profile/13722539859652296773noreply@blogger.com
