Depends on what you mean by spirituality. If that has something to do with spirits, then no I don't believe in spirituality since I don't believe in spirits. My brain is simply a big heap of matter and energy. To say that spirits are immaterial is to say that they don't exist; I only believe in things which can be shown to exist, so if there is something that I would call a "spirit" it is the collection of neural signals in my brain. I just don't use that word for it since it's not what most people understand a spirit to be.

But I think this forum is more for discussing worldviews in general rather than spirits in particular. It just so happens that a lot of people's worldviews involve immaterial spirits of some kind, and mine is grounded in science instead, and a lot if not the majority of the discussion centers around this difference, because the two worldviews are mutually incompatible.
