In connection with the previous few posts, Humanistic Judaism offers, I think, a rational and ethical perspective.

"Humanistic Judaism is a movement within Judaism that emphasizes Jewish culture and history - rather than belief in God - as the sources of Jewish identity. Its rituals and ceremonies do not include prayer or any invocation of a deity. Its philosophical outlook is derived from Humanism or Secular Humanism, and its beliefs may be summarized as follows..."

"Ethics and morality should serve human needs, and choices should be based upon consideration of the consequences of actions rather than pre-ordained rules or commandments"

Surely there are a great many people from other religious cultures with similar 'Humanistic' perspectives. Well, at least, I like to think so.
