is now, therefore, time to pass on to those matters, which appertain to the duration of the mind, without relation to the body. Prop. XXI. The mind can only imagine anything, or remember what is past, while the body endures. Proof.- The mind does not express the actual existence of its body, nor does it imagine the modifications of the body as actual, except while the body endures (II:viii.Coroll.); and, consequently (II:xxvi.), it does not imagine any body as actually existing, except while its own body endures.

This essence, therefore, must necessarily be conceived through the very essence of God (I:Ax.iv.), and be thus conceived by a certain eternal necessity (I:xvi.); and this conception. must necessarily exist in God (II:iii.). Q.E.D. Prop. XXIII. The human mind cannot be absolutely destroyed with the body, but there remains of it something which is eternal. Proof.- There is necessarily in God a concept or idea, which expresses the essence of the human body (last Prop.), which, therefore, is necessarily something appertaining to the essence of the human mind (II:xiii.). But we have not assigned to the human mind any, duration, definable by time, except in so far as it expresses the actual existence of the body, which is explained through duration, and may be defined by time - that is (II:viii.Coroll.), we do not assign to it duration, except while the body endures.…
