As is well known, speech acts such as acts of promising can have ontological consequences. For example an act of promising can give rise to a mutually correlated claim and obligation. Increasingly, speech acts in the narrow sense are being augmented by the use of documents of multiple different sorts. In this paper we analyze the results of this augmenta-tion from the ontological point of view, considering especially the domains of law and com-merce. We show how document acts are not isolated phenomena, but rather form large and complex systems with other entities, including occurrent entities such as acts of signing and inspecting, as well as speech acts for example of instructing people to sign or complete a doc-ument. The paper concludes with a consideration of some of the special problems associated with the use of digital documents, for example as concerns issues of security and provenance.

The paper introduces the concepts at the heart of point-set-topology and of mereotopology (topology founded in the non-atomistic theory of parts and wholes) in an informal and intuitive fashion. It will then seek to demonstrate how mereotopological ideas can be of particular utility in cognitive science applications. The prehistory of such applications (in the work of Husserl, the Gestaltists, of Kurt Lewin and of J. J. Gibson) will be sketched, together with an indication of the field of possibilities in linguistics, perceptual psychology, cate¬gorization and geographic information systems. Topological structures will be shown to play a central role in studies of naive physics not least in virtue of the fact that even well-attested departures from true physics on the part of common sense leave the topology and vectorial orientation of the underlying physical phenomena invariant: our common sense would thus seem to have a veridical grasp of the topology and broad general orientation of physical phenomena, both static and dynamic, even where it illegitimately modifies the relevant shape and metric properties. The implications of this and related insights for the methodology of psychology will be explored.

At the beginning of the present century, a series of paradoxes were discovered within mathematics which suggested a fundamental unclarity in traditional mathemati­cal methods. These methods rested on the assumption of a realm of mathematical idealities existing independently of our thinking activity, and in order to arrive at a firmly grounded mathematics different attempts were made to formulate a conception of mathematical objects as purely human constructions. It was, however, realised that such formulations necessarily result in a mathematics which lacks the richness and power of the old ‘platonistic’ methods, and the latter are still defended, in various modified forms, as embodying truths about self-existent mathematical entities. Thus there is an idealism-realism dispute in the philosophy of mathematics in some respects parallel to the controversy over the existence of the experiential world to the settle­ment of which lngarden devoted his life. The present paper is an attempt to apply Ingarden’s methods to the sphere of mathematical existence. This exercise will reveal new modes of being applicable to non-real objects, and we shall put forward arguments to suggest that these modes of being have an importance outside mathematics, especially in the areas of value theory and the ontology of art

As conceived by analytic philosophers ontology consists in the application of the methods of mathematical logic to the analysis of ontological discourse. As conceived by realist philosophers such as Meinong and the early Husserl, Reinach and Ingarden, it consists in the investigation of the forms of entities of various types. The suggestion is that formal methods be employed by phenomenological ontologists, and that phenomenological insights may contribute to the construction of adequate formal-ontological languages. The paper sketches an account of what might be involved in this new discipline, an account which is illustrated in application to the formal-ontological problems raised by negative states of affairs.

"'It is clear", wrote Wittgenstein in the Tractatus, "that ethics has nothing to do with punishment and reward in the usual sense of the terms" (6.422). But he insisted also that there must be some kind of ethical punishment and reward; "the reward", he tells us, "must be something pleasant, and the punishment something unpleasant" (ibid.). I argue that we can understand what Wittgenstein meant by "reward" and "punishment" by conceiving these notions as elements in a system of interrelated concepts connected with the idea of law.

There is a narrow thread in the vast literature on Kafka which pertains to Kafka’s knowledge of philosophy, and more precisely to Kafka’s use in his fictional writings of some of the main ideas of Franz Brentano. Kafka attended courses in philosophy at the Charles University given by Brentano’s students Anton Marty and Christian von Ehrenfels, and was for several years a member of a discussion-group organized by orthodox adherents of the Brentanian philosophy in Prague. The present essay summarizes what is known about Kafka’s relations to the Brentanist movement. It draws on Brentanian ideas on the evidence of inner perception, on oblique consciousness, on active introspection, on correct and incorrect judgment, and on consciousness as a species of inner tribunal, in order to throw light on central features of Kafka’s writings, including stylistic features. Special attention is directed towards Die Verwandlung and Der Prozess, and a reading of the latter is offered according to which the trial of Joseph K. occurs entirely within the mind of K. himself. The revisions in the 1997 version of the paper relate especially to the treatment of Kafka and Brentano in Arnold Heidsieck’s book The Intellectual Contexts of Kafka’s Fiction: Philosophy, Law, Religion, of 1994.

It will be the thesis of this paper that there are among our mental acts some which fall into the category of real material relations. That is: some acts are necessarily such as to involve a plurality of objects as their relata or fundamenta. Suppose Bruno walks into his study and sees a cat. To describe the seeing, here, as a relation, is to affirm that it serves somehow to tie Bruno to the cat. Bruno's act of seeing, unlike his feeling depressed, his putative thinking-about-Santa-Claus or his musing, abstractedly, about the tallest spy, has at least two fundamenta: it is, as a matter of necessity, dependent for its existence upon both Bruno himself and the cat that he sees. This idea will naturally raise echoes of Russell's doctrine of knowledge by acquaintance. 'I am acquainted with an object', Russell tells us, 'when I have a direct cognitive relation to that object, i. e. when I am directly aware of the object itself' (1918, p. 209). And indeed a distinction in many ways like that between acquaintance and description will find a place within the theory here projected, but there are crucial differences.

Der vorliegende Aufsatz stellt den Versuch dar, die normative Seite von Wittgensteins Frühwerk herauszuarbeiten und dabei an seinem Ansatz insofern Kritik zu üben, als gezeigt wird, wie sehr dessen Implikationen mit unseren üblichen ethischen Vorstellungen in Konflikt stehen. Die Arbeit hat aber auch einen etwas wohlwollenderen Aspekt: Sie versucht zu zeigen, wie Wittgensteins scheinbar widersinnige Ansichten so formuliert werden können, daß sie zumindest begreifbar erscheinen. Zu diesem Zweck beginnen wir mit der Untersuchung des demjenigen Wittgensteins erstaunlich ähnlichen ethischen Ansatzes, wie er von einem seiner frühen väterlichen Freunde vertreten wurde, nämlich von Karl Kraus.

The paper seeks to develop an account of indexical phenomena based on the highly general theory of structure and dependence set forth by Husserl in his Logical Investigations. Husserl here defends an Aristotelian theory of meaning, viewing meanings as species or universals having as their instances certain sorts of concrete meaning acts. Indexical phenomena are seen to involve the combination of such acts of meaning with acts of perception, a thesis here developed in some detail and contrasted with accounts of indexicals suggested by Frege, Wittgenstein and by the later Husserl himself in his Ideas I. Implications are drawn also for our understanding of the categorial grammar sketched by Husserl in his 4th Logical Investigation, as also for our understanding of the nature of proper names and other candidate indexical expressions

‘What is characteristic of every mental activity’, according to Brentano, is ‘the reference to something as an object. In this respect every mental activity seems to be something relational.’ But what sort of a relation, if any, is our cognitive access to the world? This question – which we shall call Brentano’s question – throws a new light on many of the traditional problems of epistemology. The paper defends a view of perceptual acts as real relations of a subject to an object. To make this view coherent, a theory of different types of relations is developed, resting on ideas on formal ontology put forward by Husserl in his Logical Investigations and on the theory of relations sketched in Smith's "Acta cum fundamentis in re". The theory is applied to the notion of a Cambridge change, which proves to have an unforeseen relevance to our understanding of perception.

Ingarden’s puzzle is: how can we come to know what is essentially involved in an act of knowing? As starting point he takes what he holds to be a particular good candidate example of such an act, namely an act of perceiving an apple. Here we have act and object standing in a certain first-level relation to each other. We now in a second level act of reflection, make this first-level relation into an object, and strive to apprehend this object as an instantiation of the essence knowledge. But how, on this basis, could we ever establish that we had indeed grasped this essence, and that this is indeed the appropriate essence? Surely, through some third-level act of reflection on this second-level act. We expound from an ontological point of view Ingarden's idea as to how this regress can be avoided.

This essay is an introduction to a lecture course "Elements of Descriptive Psychology" delivered by Anton Marty in around 1903/04. Marty offered courses on descriptive psychology at regular intervals in the course of his career at the University of Prague. The content of these courses follows closely the ideas of Marty’s teacher Franz Brentano, though with some interesting divergences and extrapolations. The present work is a historical and systematic introduction to an extract from notes taken of Marty’s lecture, with some discussion of the work of Dilthey on similar topics, and of Marty’s influence on Franz Kafka and on the Gestalt psychologist Max Wertheimer

The current resurgence of interest in cognition and in the nature of cognitive processing has brought with it also a renewed interest in the early work of Husserl, which contains one of the most sustained attempts to come to grips with the problems of logic from a cognitive point of view. Logic, for Husserl, is a theory of science; but it is a theory which takes seriously the idea that scientific theories are constituted by the mental acts of cognitive subjects. The present essay begins with an exposition of Husserl's act-based conception of what a science is, and goes on to consider his account of the role of linguistic meanings, of the ontology of scientific objects, and of evidence and truth. The essay concentrates almost exclusively on the Logical Investigations of 1900/01. This is not only because this work, which is surely Husserl's single most important masterpiece, has been overshadowed first of all by his Ideas I and then later by the Crisis. It is also because the Investigations contain, in a peculiarly clear and pregnant form, a whole panoply of ideas on logic and cognitive theory which either simply disappeared in Husserl's own later writings or became obfuscated by an admixture of that great mystery which is 'transcendental phenomenology'.

Johannes Daubert he was an acknowledged leader, and in some respects the founder, of the early phenomenological movement, and was considered – as much by its members as by Husserl himself – the most brilliant member of the group. In Daubert’s unpublished writings we find a series of reflections on Lask, and on Neo-Kantianism, which form the subject-matter of this paper. They range over topics such as the ontology of the ‘Sachverhalt’ or state of affairs, truthvalues (Wahrheitswerte) and the value of truth, negative judgments and the copula, and the relation between perception and judgment.

Relevance logic has become ontologically fertile. No longer is the idea of relevance restricted in its application to purely logical relations among propositions, for as Dunn has shown in his (1987), it is possible to extend the idea in such a way that we can distinguish also between relevant and irrelevant predications, as for example between “Reagan is tall” and “Reagan is such that Socrates is wise”. Dunn shows that we can exploit certain special properties of identity within the context of standard relevance logic in a way which allows us to discriminate further between relevant and irrelevant properties, as also between relevant and irrelevant relations. The idea yields a family of ontologically interesting results concerning the different ways in which attributes and objects may hang together. Because of certain notorious peculiarities of relevance logic, however,1 Dunn’s idea breaks down where the attempt is made to have it bear fruit in application to relations among entities which are of homogeneous type.

The paper seeks to show how the world of everyday human cognition might be treated as an object of ontological investigation in its own right. The paper is influenced by work on affordances and prototypicality of psychologists such as Gibson and Rosch, by work on cognitive universals of the anthropologist Robin Horton, and by work of Patrick Hayes and others on ‘naive’ or ‘qualitative physics’. It defends a thesis to the effect that there is, at the heart of common sense, a theoretical core of true propositions pertaining to mesoscopic objects, and that the latter are to be understood as relating mereologically to the objects studied by physical science.
