 Cockburn points out that Locke never sets out to prove the soul immortal, and Locke actually claims that it is more probable that the soul is immaterial, than material. Moreover, even if Locke is not committed to the soul being immaterial, this ought not threaten proofs of the immortality of the soul. This is because what allows Locke to speculate that God could have superadded thinking to formerly inert systems of matter is that God is omnipotent, and surely an omnipotent being could make souls immortal even if they are material. Moreover, proofs for the immortality of the soul that rely on the immateriality of the soul are not likely to convince laymen of the soul’s immortality, and may actually leave them sceptical about whether the soul is indeed immortal (even if it is immaterial).
