I. ON THE ARRANGEMENT OF THE BOOK AND ITS SUBDIVISIONS<br />
1. <strong>The</strong> essays collected in this book do not constitute a systematic statement of one <strong>and</strong> <strong>the</strong><br />
same doctrine; <strong>the</strong>y present <strong>Brentano</strong>’s thinking in its living development.<br />
<strong>Brentano</strong>’s epistemology had been based upon <strong>the</strong> Aristotelian <strong>the</strong>ory; but <strong>the</strong> lecture on<br />
truth, which is <strong>the</strong> first selection published here, shows that even in 1889 he was not entirely<br />
satisfied with Aristotle. <strong>Brentano</strong> had revised <strong>the</strong> Aristotelian <strong>the</strong>ory of judgement <strong>and</strong> in<br />
consequence found it necessary to criticize <strong>the</strong> view that truth consists in an adaequatio rei<br />
et intellectus. In addition to syn<strong>the</strong>tic, categorical judgements of <strong>the</strong> form “S is P”, <strong>the</strong>re<br />
are also, according to <strong>Brentano</strong>, simple, <strong>the</strong>tic judgements of <strong>the</strong> form “S is”. Contrary to<br />
<strong>the</strong> Aristotelian <strong>the</strong>ory, <strong>the</strong>se <strong>the</strong>tic judgements, even when <strong>the</strong>y are true, cannot be said to<br />
combine what is combined in reality, or to separate what is separated in reality. One can say<br />
of such judgements only that <strong>the</strong>y accept something or that <strong>the</strong>y reject something. Hence<br />
according to <strong>the</strong> conclusion of this early lecture, a judgement is true provided ei<strong>the</strong>r that it<br />
says, of something that is, that it is, or that it denies, of something that is not, that it is.<br />
Since every syn<strong>the</strong>tic judgement is logically equivalent to a <strong>the</strong>tic judgement (“S is P”<br />
is equivalent to “SP is”), this particular definition of truth, representing <strong>Brentano</strong>’s earlier<br />
views, was sufficiently comprehensive. Never<strong>the</strong>less it was untenable, <strong>and</strong> <strong>Brentano</strong> could<br />
not permanently conceal this fact from himself. It had always been characteristic of his<br />
<strong>the</strong>ory of knowledge to proceed on <strong>the</strong> basis of <strong>the</strong> insightful judgement, or <strong>the</strong> judgement<br />
that is seen to be correct. For a considerable period of time, however, he felt that one could<br />
remain within <strong>the</strong> Aristotelian tradition by interpreting truth or correctness in terms of<br />
correspondence, adequacy, or appropriateness—this in contradiction with his own view.<br />
Even <strong>the</strong> break with tradition which is heralded by <strong>the</strong> work of Descartes (whom <strong>Brentano</strong><br />
held in high esteem) <strong>and</strong> which is even more clearly set forth by Spinoza, was not enough<br />
to emancipate him from this ambiguous interpretation.<br />
It was <strong>Brentano</strong>’s conception of <strong>the</strong> existential proposition which required him to<br />
modify <strong>the</strong> correspondence <strong>the</strong>ory of Aristotle; this modification may be seen in <strong>the</strong> first<br />
two selections here <strong>and</strong> also, to some extent, in <strong>the</strong> fifth. According to <strong>the</strong> modified <strong>the</strong>ory,<br />
true judgements are no longer said to correspond with things <strong>and</strong> <strong>the</strong>ir properties; <strong>the</strong>y<br />
correspond instead with <strong>the</strong> being or <strong>the</strong> non-being of things—with <strong>the</strong>ir existence or nonexistence.<br />
In Section 57 of <strong>the</strong> lecture on truth, <strong>the</strong> first of <strong>the</strong>se selections, <strong>Brentano</strong> explicitly states<br />
that he would explicate <strong>the</strong> truth of an affirmative judgement by means of <strong>the</strong> correlative<br />
concept of <strong>the</strong> existence of <strong>the</strong> object, <strong>and</strong> that he would explicate <strong>the</strong> truth of a negative<br />
judgement by means of <strong>the</strong> correlative concept of <strong>the</strong> non-existence of <strong>the</strong> object.
