We now come to the final propositions of the _Ethic_, those in which Spinoza declares his belief in the eternity of mind. The twenty-second and twenty-third propositions of the fifth part are as follows:— “In God, nevertheless, there necessarily exists an idea which expresses the essence of this or that human body under the form of eternity.” “The human mind cannot be absolutely destroyed with the body, but something of it remains which is eternal.” The word “nevertheless” is a reference to the preceding proposition which denies the continuity of memory or imagination excepting so long as the body lasts. The demonstration of the twenty-third proposition is not easy to grasp, but the substance of it is that although the mind is the idea of the body, that is to say, the mind is body as thought and body is thought as extension, the mind, or essence of the body, is not completely destroyed with the body. It exists as an eternal idea, and by an eternal necessity in God. Here again we must not think of that personality which is nothing better than a material notion, an image from the concrete applied to mind, but we must cling fast to thought, to the thoughts which alone makes us what we _are_, and these, says Spinoza, are in God and are not to be defined by time. They have always been and always will be. The enunciation of the thirty-third proposition is, “The intellectual love of God which arises from the third kind of knowledge is eternal.” The “third kind of knowledge” is that intuitive science which “advances from an adequate idea of the formal essence of certain attributes of God to the adequate knowledge of the essence of things;” {54} “No love except intellectual love is eternal,” {55a} and the scholium to this proposition adds, “If we look at the common opinion of men, we shall see that they are indeed conscious of the eternity of their minds, but they confound it with duration, and attribute it to imagination or memory, which they believe remain after death.” The intellectual love of the mind towards God is the very “love with which He loves Himself, not in so far as He is infinite, but in so far as He can be manifested through the essence of the human mind, considered under the form of eternity; that is to say, the intellectual love of the mind towards God is part of the infinite love with which God loves Himself.” {55b} “Hence it follows that God, in so far as He loves Himself, loves men, and consequently that the love of God towards men and the intellectual love of the mind towards God are one and the same thing.” {55c} The more adequate ideas the mind forms “the less it suffers from those affects which are evil, and the less it fears death” because “the greater is that part which remains unharmed, and the less consequently does it suffer from the affects.” It is possible even “for the human mind to be of such a nature that that part of it which we
