10555. 'As a man (vir) speaks to [his] neighbour' means the joining together of truth and good. This is clear from the meaning of 'speaking' as reciprocal perception and the consequent joining together, as immediately above in 10554; from the meaning of 'man' (vir) as truth, dealt with in 3134, 3459, 4823, 7716, 9007; and from the meaning of 'neighbour' as good to which truth is joined. Various places in the Word use the expression 'man and neighbour' or 'man and companion', and by it in a reciprocal way is meant, as also by 'man and brother'. And when in a reciprocal way is meant a reciprocal joining together should be understood, like that of truth and good. For truth joins itself in a reciprocal way with good, because truth derives its being from good, and good receives its specific quality in truth. No truth exists in heaven that is not joined to good, because without good truth is not anything; nor is good anything without truth. For truth without good is like the receiver of being without the giver of being, and good without truth is like the giver of it without the receiver. Or truth without good is like a body without life, and good without truth is like life without a body. Therefore unless the two are joined together they are not anything that can accomplish anything; that is, they are not anything to which anything of heaven and the Church can be attributed.
[2] The situation when one is without the other is similar to that when the human understanding exists without the will, or the will without the understanding. One may indeed become separated from the other, as when there is an understanding of what is true and good but no will to do it. In this case however the understanding has a will derived from a source other than that which is good. It derives it from willing well to self, or [to others] for the sake of self, with the understanding of what is true and good serving as means to this end. Those who reflect correctly on the matter may recognize that the human understanding derives its life from its will, without which it is not anything, and also that understanding and will turn to each other and are linked together. A similar situation exists with truth and good, consequently with faith and love. Unless truth is linked to good, or faith to love, there is no truth or good, nor any faith or love. These matters have been mentioned in order that people may know what to understand by a linking of each to the other, meant in the spiritual sense by 'man and companion' or 'man and neighbour', and also by 'man and brother'.
