Editing Immortality (section)

===Moses Mendelssohn===
[[Moses Mendelssohn]]'s ''[[Phaedon]]'' is a defense of the simplicity and immortality of the soul. It is a series of three dialogues, revisiting the Platonic dialogue ''[[Phaedo]]'', in which [[Socrates]] argues for the immortality of the soul, in preparation for his own death. Many philosophers, including Plotinus, Descartes, and Leibniz, argue that the soul is simple, and that because simples cannot decompose they must be immortal. In the Phaedon, Mendelssohn addresses gaps in earlier versions of this argument (an argument that Kant calls the Achilles of Rationalist Psychology). The Phaedon contains an original argument for the simplicity of the soul, and also an original argument that simples cannot suddenly disappear. It contains further original arguments that the soul must retain its rational capacities as long as it exists.<ref>Sassen, B. (2008).
