الأخلاق، الجزء V، القضية 38

The mind's essence consists in knowledge (II. xi.); therefore, in proportion as the mind understands more things by the second and third kinds of knowledge, the greater will be the part of it that endures (V. xxix. and xxiii.), and, consequently (by the last Prop.), the greater will be the part that is not touched by the emotions, which are contrary to our nature, or in other words, evil (IV. xxx.). Thus, in proportion as the mind understands more things by the second and third kinds of knowledge, the greater will be the part of it, that remains unimpaired, and, consequently, less subject to emotions, &c. Q.E.D.

Hence we understand that point which I touched on in IV. xxxix. note, and which I promised to explain in this Part; namely, that death becomes less hurtful, in proportion as the mind's clear and distinct knowledge is greater, and, consequently, in proportion as the mind loves God more. Again, since from the third kind of knowledge arises the highest possible acquiescence (V. xxvii.), it follows that the human mind can attain to being of such a nature, that the part thereof which we have shown to perish with the body (V. xxi.) should be of little importance when compared with the part which endures. But I will soon treat of the subject at greater length.
