I think true materialists must deny its existence or at least hand wave it away.
So that would the philosophy of illogical assumption ?
Where does information come from if not from a mind??
True that could be said of spiritualists as well though.
Atheists compose their ideologies based upon evidence of matter., spiritualists compose their ideologies upon hearsay, imagination and human ignorance.
We all have a choice to where we want to set are aspirations.
I like atheism myself because it leaves the responsibility of improving the human experience toward are selves, rather to wait on a god of ancient mythological hearsay to improve the human experience.
The fact that humanity hasn't envisioned any new gods for very long time tells a story in itself doesn't it ?
