I'm now working on an essay on the Shekhinah as an afterword to a long poem that sprung from the research and that I'm publishing this summer, and to a performance piece using some of the same text. They are not part of my observance. I don't understand the atheist outlook. The concept of fitness, as used in evolutionary biology, has no normative significance. That is why those Nazis who turned against Christianity, presumably because of its Jewish origins, tried to replace it with Wotanism, NOT atheism.
Humanistic ethics stands or falls with the natural laws on which it is based.
Thus, its laws no more allow of exceptions than the laws of physics or of chemistry. Judaism became an ethical religion when the Rabbis decided that God doesn't make exceptions any more. Unfortunately, some of its daughter religions have not yet reached this point. Much racism finds its basis in religion. And Hitler argued that his views were based on God.
