Immortality of the Soul and Vitalism

The concept of the Immortality of the Soul is Atomistic--it affirms the continued existence of an Individual after its separation from the Species.  However, despite his anti-Atomist Vitalism of Thus Spoke Zarathustra, Nietzsche misses this feature of the after-worldly doctrines that are the targets of his Dionysianism.  That may be because the Apollonian dimension of his doctrine is paradoxical--the Individual that it creates may be irreal in some respect, but the Apollonian principle itself is as real as is the Dionysian, a paradox that he inherits from Schopenhauer.  So, without a substantive alternative, he cannot quite invalidate the concept of an Immortal Soul, even while consigning it to Irreality.  However, a substantive alternative is available--the concept of the Individual as a Part, rather than as an Atom, and, likewise, the interpretation of the Apollonian as Diversification, rather than as Atomization.  On the basis of that alternative, Vitalism can entail a Principle of Individuation, and can unequivocally repudiate the concept of the Immortal Soul as antithetical to Life-affirmation.
