Sometimes atheists come up with remarkably stupid demands, such as this one:
First, I would note that this epistemological “rule” is itself stupid. If one cannot speak of things before “proving” they exist, one cannot propose the existence of things in a hypothetical manner, which (1) is the end of science, and (2) renders it impossible to prove anything exists in any case, since one is not allowed to speak about it.
But this one is particularly stupid.
The soul is the ψυχή or psychē. It is the object of the science of psychology. Another name for it is “the mind.”
It can be “proven” to exist in two words: COGITO SUM.
For those of you who don’t know that bit of Latin, it is Descartes’ famous “I think; I am.”
The existence of the mind or soul is self-evident to anyone able to pose the question of the existence of the soul (or anything else), since being a being that is capable of thinking and questioning first requires one have a mind or soul.
It is LITERALLY IMPOSSIBLE to doubt the existence of one’s own soul, since one IS one’s own soul, in the primary sense. If may be the case (and is) that the soul is intimately linked with the body, my soul with my body, but however close the two, they are not logically identical or inseparable. One can both conceive of and imagine (the two are not the same), one’s conscious awareness being moved to and inhabiting another body.
One cannot, however, conceive of oneself as not identical or separable from one’s self, which is yet another synonym for one’s soul or mind.
