Of truth in its proper sense it has often been said that it is the agreement of the judgment with the object (adequatio rei et intellectus, as the scholastics said). This expression, true in a certain sense, is yet in the highest degree open to misunderstanding, and has led to serious errors. The agreement is regarded as a kind of identity between something contained in the judgment, or in the idea lying at the root of the judgment and something situated without the mind. But this cannot be the meaning here; “to agree” means here rather as much as “to be appropriate,” “to be in harmony with,” “suit,” “correspond.” It is as though in the sphere of feeling one should say, the rightness of love and hate consists in the agreement of the feelings with the object. Properly understood this also would be unquestionably right; whoever loves and hates rightly, has his feelings adequately related to the object, i.e. the relation is appropriate, suitable, corresponds suitably, whereas it would be manifestly absurd were one to believe that in a rightly directed love or hate there was found to be an identity between these feelings or the ideas lying at their root on the one hand, and something lying outside the feelings on the other, an identity which is absent where the attitude of the feelings is unrightly directed. Among other circumstances this misunderstanding has also conduced towards bringing the doctrine of judgment into that sad confusion from which to-day psychology and logic seek with such painful efforts to set themselves free. The conceptions of existence and non-existence are the correlates of the conceptions of the truth of the (simple) affirmative and negative judgments. Just as to judgment belongs what is judged, to the affirmative judgment what is judged of affirmatively, to the negative judgment, what is judged of negatively, so to the rightness of the affirmative judgment belongs the existence of what is judged of affirmatively, to the rightness of the negative judgment the non-existence of what is judged of negatively; and whether I say an affirmative judgment is true, or, its object is existent; whether I say a negative judgment is true, or its object is non-existent; in both cases I am saying one and the same thing. In the same way, it is essentially one and the same logical principle whether I say, in each case either the (simple) affirmative or negative judgment is true, or, each is either existent or non-existent.
