Ingvar Johansson has argued that there are not only determinate universals, but also determinable ones. I here argue that this view is misguided by reviving a line of argument to the following effect: what makes determinates falling under a same determinable similar cannot be distinct from what makes them different. If true, some similarities — imperfect similarities between simple determinate properties — are not grounded in any kind of property-sharing. I suggest that determinables are better understood as maximal disjunctions of (...) brutely and imperfectly similar determinates. Such brute similarities have been thought to clash with realism about universals. I argue that this worry stems from the mistaken assumption that perfect and imperfect similarities are relations of a same kind. If exact and inexact resemblances are distinct and heterogeneous explananda, the realist about universals might explain the first thanks to property-sharing, while happily leaving imperfect similarities between properties unexplained.

This paper develops an endurantist theory of persistence. The theory is built around one basic tenet, which concerns existence at a time – the relation between an object and the times at which that object is present. According to this tenet, which I call transcendentism, for an object to exist at a time is for it to participate in events that are located at that time. I argue that transcendentism is a semantically grounded and metaphysically fruitful. It is semantically grounded, (...) insofar as a semantic analysis of our temporal talk favors it over rivals. It is metaphysically fruitful, insofar as the theory of persistence that can be built around it – the transcendentist theory of persistence, to give it a name – requires neither temporal parts nor the problematic commitments to which all extant forms of endurantism are committed, such as the possibility of extended simples or multilocation.

A sensible quality is a perceptible property, a property that physical objects (or events) perceptually appear to have. Thus smells, tastes, colors and shapes are sensible qualities. An egg, for example, may smell rotten, taste sour, and look cream and round.1,2 The sensible qualities are not a miscellanous jumble—they form complex structures. Crimson, magenta, and chartreuse are not merely three different shades of color: the first two are more similar than either is to the third. Familiar color spaces or color (...) solids capture, to a greater or lesser extent, these relations between the colors. The same goes for sensible qualities perceived in other modalities: middle C, high C, and D are not merely three different notes, and the taste of lemons, oranges, and sugar cubes are not merely three different tastes. How can this structure of appearance be explained? One idea is that sensible qualities are of two sorts: basic and derived. The basic sensible qualities are the building blocks from which the derived sensible qualities can be.. (shrink)

According to naïve realist (or primitivist) theories of colour, colours are sui generis mind-independent properties. The question that I consider in this paper is the relationship of naïve realism to what Mark Johnston calls Revelation, the thesis that the essential nature of colour is fully revealed in a standard visual experience. In the first part of the paper, I argue that if naïve realism is true, then Revelation is false. In the second part of the paper, I defend naïve realism (...) against a number of objections.

This book contains the definitive statement of Franz Brentano's views on meta physics. It is made up of essays which were dictated by Brentano during the last ten years of his life, between 1907 and 1917. These dictations were assembled and edited by Alfred Kastil and first published by the Felix Meiner Verlag in 1933 under the title Kategorienlehre. Kastil added copious notes to Brentano's text. These notes have been included, with some slight omissions, in the present edition; the bibliographical (...) references have been brought up to date. Brentano's approach to philosophy is unfamiliar to many contemporay readers. I shall discuss below certain fundamental points which such readers are likely to find the most difficult. I believe that once these points are properly understood, then what Brentano has to say will be seen to be of first importance to philosophy. THE PRIMACY OF THE INTENTIONAL To understand Brentano's theory of being, one must realize that he appeals to what he calls inner perception for his paradigmatic uses of the word "is". For inner perception, according to Brentano, is the source of our knowledge of the nature of being, just as it is the source of our knowledge of the nature of truth and of the nature of good and evil. And what can be said about the being of things that are not apprehended in inner perception can be understood only by analogy with what we are able to say about ourselves as thinking subjects.

Physical boundaries and the earliest topologists. Topology has a relatively short history; but its 19th century roots are embedded in philosophical problems about the nature of extended substances and their boundaries which go back to Zeno and Aristotle. Although it seems that there have always been philosophers interested in these matters, questions about the boundaries of three-dimensional objects were closest to center stage during the later medieval and modern periods. Are the boundaries of an object actually existing, less-than-three-dimensional parts of (...) the object—that is, are solids bounded by two-dimensional surfaces, surfaces by one-dimensional “edges” or “physical lines”, edges by dimensionless “simples”? If not, how does a perfectly spherical object manage to touch a perfectly flat object—what part of the sphere is in immediate contact with the plane, if the sphere has no unextended parts? But if such parts be admitted, are we not then saddled with “actual infinities” of simples, lines, and surfaces spread throughout each continuous object—the boundaries of all the object’s internal parts? Does it help to say that these internal boundaries exist only “potentially”? (shrink)

There are conflicting intuitions concerning the status of a boundary separating two adjacent entities (or two parts of the same entity). The boundary cannot belong to both things, for adjacency excludes overlap; and it cannot belong to neither, for nothing lies between two adjacent things. Yet how can the dilemma be avoided without assigning the boundary to one thing or the other at random? Some philosophers regard this as a reductio of the very notion of a boundary, which should accordingly (...) be treated a mere façon de parler. In this paper I resist this temptation and examine some ways of taking the puzzle at face value within a realist perspective—treating boundaries as ontologically on a par with (albeit parasitic upon) extended parts.

I offer a reconstruction of Brentano's view of inner consciousness and show how Brentano prevented a regress of higher-order mental acts.

Brentano held that every mental phenomenon has an object and is conscious (the dual relation thesis). The dual relation thesis faces a number of well-known problems. The paper explores how Brentano tried to overcome these problems. In considering Brentano's responses, the paper sheds light on Brentano's theory of judgement that underpins his philosophy of mind.

In his Psychologie vom empirischen Standpunkt Brentano proposed a view of consciousness that neither has room nor need for a subject of mental acts, a soul. Later he changed his mind: there is a soul that appears in consciousness. In this paper I will argue that Brentano’s change of view is not justified. The subjectless view of consciousness can be defended against Brentano’s argument and it is superior to its predecessor.

We discuss two modal claims about the phenomenal structure of color experiences: (i) violet experiences are necessarily experiences of a color that is for the subject on that occasion phenomenally composed of red and blue (the modal claim about violet) and (ii) no subject can possibly have an experience of a color that is for it then phenomenally composed of red and green (the modal claim about reddish green). The modal claim about reddish green is undermined by empirical results. We (...) discuss whether these empirical results cast doubt on the other modal claims as well. We argue that this not the case. Our argument is based on the thesis that the best argument for the modal claim about violet is quite different from the best argument for the modal claim about reddish green. To argue for this disanalogy we propose a reconstruction of the best available justification for both claims. (shrink)

What follows is an investigation of the ontology of Franz Brentano with special reference to Brentano's later and superficially somewhat peculiar doctrine to the effect that the substances of the material world are three dimensional places. Taken as a whole, Brentano's philosophy is marked by three, not obviously compatible, trait. In the first place, his work is rooted in the metaphysics of Aristotle, above all in Aristotle's substance/accident ontology and in the Aristotelian theory of categories. In the second place, Brentano (...) embraced a Cartesian epistemology. He saw the source of all knowledge as residing in our direct awareness of our own mental phenomena and in our capacity to grasp evident incompatibilities in the realm of concepts.) Thirdly, he regarded the existence of an external world as at most probable, and denied outright the existence of a world similar to the world that is given in experience. Finally, and in some sense linking together these opposing strands, he propagated an idea of what he called "descriptive psychology", a discipline which would on the one hand yield exact knowledge of the structures and categories of mental life, and on the other hand provide an epistemologically sure foundation for other branches of philosophy. As we shall see, it is this psychological aspect of Brentano's philosophy which leads him to his conception of the substantiality of place. Surprisingly, however, the psychological considerations which underlie Brentano's thinking will be shown to raise a series of questions strictly ontological in nature, questions which are not without a systematic interest of their own.

This is a review article on Franz Brentano’s Descriptive Psychology published in 1982. We provide a detailed exposition of Brentano’s work on this topic, focusing on the unity of consciousness, the modes of connection and the types of part, including separable parts, distinctive parts, logical parts and what Brentano calls modificational quasi-parts. We also deal with Brentano’s account of the objects of sensation and the experience of time.

Persistence through time is like extension through space. A road has spatial parts in the subregions of the region of space it occupies; likewise, an object that exists in time has temporal parts in the various subregions of the total region of time it occupies. This view — known variously as four dimensionalism, the doctrine of temporal parts, and the theory that objects “perdure” — is opposed to “three dimensionalism”, the doctrine that things “endure”, or are “wholly present”.1 I will (...) attempt to resolve this dispute in favor of four dimensionalism by means of a novel argument based on considerations of vagueness. But before argument in this area can be productive, I believe we must become much clearer than is customary about exactly what the dispute is, for the usual ways of formulating the dispute are flawed, especially where three dimensionalism is concerned.

What is the relation between material objects and spacetime regions? Supposing that spacetime regions are one sort of substance, there remains the question of whether or not material objects are a second sort of substance. This is the question of dualistic versus monistic substantivalism. I will defend the monistic view. In particular, I will maintain that material objects should be identified with spacetime regions. There is the spacetime manifold, and the fundamental properties are pinned directly to it.

Brentano, expert et continuateur de l’ontologie aristotélicienne, traite du problème métaphysique de l’individuation dans un petit nombre d’écrits . Il retient pour ce problème une solution ordinairement rejetée, l’individuation par le lieu . À ce titre, il occupe une position originale. La notion de lieu, cependant, tout comme plus généralement la notion de l’accident, ressort tout à fait transformée des analyses de Brentano : le lieu devient une détermination substantielle, non accidentelle, des corps. Dans des écrits tardifs, Brentano étend son (...) analyse du lieu à une cosmologie qui n’admet qu’une seule substance corporelle étendue, dont les corps particuliers sont les accidents.Brentano, both expert and continuator of the Aristotelian ontology, devotes his attention to the metaphysical problem of individuation in a small number of writings collected under the title Kategorienlehre. For this problem, he adopts a solution which gets ordinarily rejected, individuation through place . Hence he occupies an original position on this issue. The notion of place, however, as well as the notion of accident more generally, gets completely transformed in the Brentanian analysis : place becomes not an accidental but a substantial determination. In some late writings, Brentano extends his analysis of place to a cosmology which admits a unique extended bodily substance, of which particular bodies are only the accidents. (shrink)

This paper takes up issues related to the notion of chemical substances arising from their mereological and modal features. Related notions are elements and compounds, into which substances are sub-divided, and the general notion of mixture, which as a special case might involve several substances, but covers other cases too. These are essentially macroscopic concepts. Some of the chemical arguments for this claim have been presented elsewhere. The present paper is a metaphysical treatment of matter as categorised by the major (...) chemical concepts bearing on distinctions between homogeneous and heterogeneous matter, and between a single and several substances.

According to immanent realism, there are universals in the spatiotemporal world quite independently of language and the mind. The existence of these universals, furthermore, is not dependent upon there being Platonic universals existing outside the spatiotemporal world. In this paper I will try to show that immanent realism holds not only for many determinate universals, but for some determinable universals as well. In other words, there are ontological determinables as well as conceptual determinables.

Aristotle raised a puzzle about the possibility of mixing whose solution is by no means obvious. I here explicate his solution to the puzzle and attempt to make it plausible within the context of his thought. Although we now know that his specific views on mixing were mistaken, his discussion of the topic raises questions concerning the role of capacities and the relationship of part to whole that are still of interest.

Une distinction entre la perception et la sensation a semblé nécessaire à la plupart des théoriciens et des philosophes, notamment parce que des sensations très différentes peuvent donner lieu à des perceptions identiques et des sensations qu'il y a tout lieu de croire identiques à des perceptions très différentes. Si tout le monde est en gros d'accord depuis longtemps pour admettre qu'il faut beaucoup plus que des sensations pour avoir une perception d'objet, il est plus difficile de dire en quoi (...) consiste cet élément supplémentaire qui doit s'ajouter à la sensation, et de quelle façon il réussit à se combiner avec elle pour donner la perception. On dit souvent que percevoir n'est pas sentir, mais avant tout juger. Mais l'identification de la perception à une simple forme particulière de jugement se révèle, à bien des égards, aussi insatisfaisante que pourrait l'être sa réduction à la simple sensation. A travers des auteurs comme Helmholtz, Husserl, Frege, essentiellement sur la nature du lien particulier qui unit la pensée à la sensation dans la perception et, plus précisément, sur la question de savoir si le jugement doit être considéré comme un accompagnement et une résultante de la perception qui le motive ou, au contraire, comme un constituant essentiel de celle-ci.

This book guides the readers through Brentano's life and works, investigating into the inherent complexity of both his view of mental life and the related methodology.

Franz Brentano (1838-1917) is a key figure in the development of Twentieth Century thought. It was his work that set Husserl on to the road of phenomenology and intentionality, that inspired Meinong's theory of the object which influenced Bertrand Russell, and the entire Polish school of philosophy. ^Descriptive Psychology presents a series of lectures given by Brentano in 1887; they were the culmination of his work, and the clearest statement of his mature thought. It was this later period which proved (...) to be so important in the work of his student, Husserl. This is the first English translation of his work. Benito Muller has added a concise introduction which places Brentano within the history of philosophy and psychology, and locates his influence in contemporary thought. (shrink)

In the Garden of Eden, we had unmediated contact with the world. We were directly acquainted with objects in the world and with their properties. Objects were simply presented to us without causal mediation, and properties were revealed to us in their true intrinsic glory.

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.
