 Recall that naturalism is the view that a physical life is central to life’s meaning, that even if there is no spiritual realm, a substantially meaningful life is possible. Like supernaturalism, contemporary naturalism admits of two distinguishable variants, moderate and extreme (Metz 2019). The moderate version is that, while a genuinely meaningful life could be had in a purely physical universe as known well by science, a somewhat more meaningful life would be possible if a spiritual realm also existed. God or a soul could enhance meaning in life, although they would not be major contributors. The extreme version of naturalism is the view that it would be better in respect of life’s meaning if there were no spiritual realm. From this perspective, God or a soul would be anti-matter, i.e., would detract from the meaning available to us, making a purely physical world (even if not this particular one) preferable.
