@Tezz By the way, concerning the dogs and cats thing, I'm reminded of something I just found in Adi Shankaracharya's Brahma Sutra Bhashya:
sacred-texts.com/hin/sbe34/sbe34164.htm The Purvapaksha argues that it's impossible for Brahman to create the world, because an intelligent beng can only create things with external helps. Adi Shankaracharya responds that that's wrong, because we observe that a female crane can conceive a child without the help of a male.
