If you don't mean to suggest you believe in some strange metaphysics without any grounding in reality, why do you call it spirituality? What "inner world" are you "exploring"? Can that be done in plain language without any mysticism? Why or why not?
we are monkeys following logic that was determined by other monkeys. our experience of reality is equivalent to that of a brain in a jar. blind belief is blind belief whether placed in science or religion. breaching the gap of blindness necessarily involves a leap to test ideas with personal faith. such a notion is not necessarily compatible with an atheistic perspective insisting reality is solely that which may be verbally quantified by monkeys. a dog knows to sit on command but has no idea about the concept of sitting, does that make the concept of sitting unreal?
Militant atheists like you are almost as insufferable as militant theists
I can see how they mean "the search for the unknown" in itself is already some sort of spirituality.
