Following Bolzano, I suggest that there are two types of entity: those that are states of other things and those that are not. The second type includes, not only substances, in the traditional sense, but also such abstract objects as numbers, attributes and propositions. It is argued that the theory of states, when combined with an intentional account of negative attributes, will yield a theory of negative entities and of events.
Roderick Chisholm has been for many years one of the most important and influential philosophers contributing to metaphysics, philosophy of mind, and epistemology. This book can be viewed as a summation of his views on an enormous range of topics in metaphysics and epistemology. Yet it is written in the terse, lucid, unpretentious style that has become a hallmark of Chisholm's work. The book is an original treatise designed to defend an original, non-Aristotelian theory of categories. Chisholm argues that there (...) are necessary things and contingent things; necessary things being things that are not capable of coming into being or passing away. He defends the argument from design, and thus includes the category of necessary substance (God). Further contentions of the essay are that attributes are also necessary beings, but not necessary substances, and that human beings are contingent substances but may not be material substances.

The concepts of a spatially continuous substance, of spatial dimension and of spatial boundary are here "analyzed out" of the concepts of individual thing, of constituent and of coincidence. The analysis is based upon the theory of spatial coincidence that was developed by Brentano. Its presuppositions are essentially these: (1) if there are spatial objects of any kind, then there are continuous spatial substances. (2) such substances are possibly such that they are not constituents of any individual thing; and (3) (...) they contain constituents (namely, boundaries) which are necessarily such that they are constituents of spatial substances.

What is the metaphysical significance of what Brentano has shown us about intentionality? It is the fact that intentional phenomena have logical or structural features that are not shared by what is not psychological. It was typical of British empiricism, particularly that of Hume, to suppose that consciousness is essentially sensible. The objects of consciousness were thought to be primarily such objects as sensations and their imagined or dreamed counterparts. In the Psychologie vom empirischen Standpunkt, Brentano makes clear that intentional (...) phenomena need not be sensible. He is aware that, even if intentional phenomena are always accompanied by sensible or sensational phenomena, they are not themselves sensational or sensible phenomena. And the presence of certain intentional attitudes is at least as certain and indubitable for us as is the presence of our sensations. If I make a certain judgment or ask myself a certain question, then I can know directly and immediately that I make that judgment or ask that question. (This is not to say, of course, that every intentional attitude may be the object of such certainty. Perhaps there is a sense in which you may be said to like or to dislike a certain thing without realizing that you like or dislike that thing.) If I can know directly and immediately that I am making a certain judgment, then, I can know what it is to make such a judgment. And if I know what it is to make a judgment, then, in making the judgment I can know directly and immediately that there is a certain individual thing - namely, the one who makes the judgment. Arid I, of course, am the one who makes my judgments and does my thinking. The same is true, obviously, of my other intentional activities - such activities as wondering, fearing, hoping, desiring, considering, liking and disliking. (shrink)
Franz Brentano developed an original theory of intrinsic value which he attempted to base on his philosophical psychology. Roderick Chisholm presents here a critical exposition of this theory and its place in Brentano's general philosophical system. He gives a detailed account of Brentano's ontology, showing how Brentano tried to secure objectivity for ethics not through a theory of practical reason, but through his theory of the intentional objects of emotions and desires. Professor Chisholm goes on to develop certain suggestions about (...) intrinsic value made by Brentano and his students, and discusses their relevance to theodicy and the problem of evil. Brentano, as the teacher of Husserl, Meinong, Twardowski, and others, stands at the origin of the phenomenological tradition and of the Polish school of philosophy that developed after World War I. He has also had considerable influence on Anglo-American philosophy. This book will interest those concerned with the origins of phenomenological value theory and more generally with the connections between ethics and philosophical psychology. (shrink)
Körner has made an important distinction between dependent and independent particulars, noting that any adequate theory of categories will divide particulars into those that are independent and those that are not. In the present paper, the concept of a spatial boundary is used to illustrate the concept of a dependent particular. It is suggested that, if we follow Brentano and think of such boundaries as ontologically dependent upon the things of which they may be said to be boundaries, then we (...) will be able to throw light upon a number of philosophical questions about the spatial continuum. These questions pertain to such topics as: the distinction between parts and boundaries; the definition of dimensionality; and the nature of contact and physical continuity. (shrink)
Schlick held that our knowledge is founded upon certain contingent apprehensions which he described as follows: "I grasp their meaning at the same time that I grasp their truth." He cites as an example the apprehension expressed by "Yellow here now." When such apprehensions are expressed in syntactically well-formed sentences, they can be seen to have certain psychological states as their objects - and therefore to be similar in all essential respects to what members of the Brentano school had called (...) "inner perceptions.". (shrink)
