Well, both, given my use of Ockham’s Razor in this context. Yes, my primary position is the former. I then say therefore I don’t believe in anything beyond the physical.
Again, it’s directly equivalent to my position regarding God. I don’t consider that God is necessary as an entity, only optional. While others don’t mind ‘keeping’ optional things (“The variety of beings should not rashly be diminished” - Kant), I prefer to do away with them altogether.
