Single Idea 5887

[filed under theme 15. Nature of Minds / A. Nature of Mind / 5. Unity of Mind ]

Full Idea

In souls there is no mingling of ingredients, nothing of two-fold nature, so it is impossible for the soul to be divided; impossible, therefore, for it to perish either; for perishing is like the separation of parts which were maintained in union.

Gist of Idea

The soul has a single nature, so it cannot be divided, and hence it cannot perish

Source

M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xxix.71)

Book Ref

A Reaction

Cicero knows he is pushing his luck in asserting that perishing is a sort of division. Why can't something be there one moment and gone the next? He appears to be in close agreement with Descartes about being a 'thinking thing'.
