Twardowski'sOn the Content and Object of Presentations(1894) is one of the most influential works that Austrian philosophy has left to posterity. The manuscriptLogik(1894–1895) supplements that work and allows us to reconstruct Twardowski's theory of judgement. These texts raise several issues, in particular whether Twardowski accepts propositions and states of affairs in his theory of judgement and whether his theory is acceptable. This article presents Twardowski's theory, shows that he accepts states of affairs, that he has a notion of proposition, and (...) that his theory is interesting and sophisticated. (shrink)

The project of a 'naive physics' has been the subject of attention in recent years above all in the artificial intelligence field, in connection with work on common-sense reasoning, perceptual representation and robotics. The idea of a theory of the common-sense world is however much older than this, having its roots not least in the work of phenomenologists and Gestalt psychologists such as K hler, Husserl, Schapp and Gibson. This paper seeks to show how contemporary naive physicists can profit from (...) a knowledge of these historical roots of their discipline, which are shown to imply above alla critique of the set-theory-based models of reality typically presupposed by contemporary work in common-sense ontology [1].

Phenomenology is intrinsically intentional for Brentano. Qualitative conscious experiences are individuated by their phenomenal space. Examples concerning the phenomenal take account of both experiential and physical spaces. As directedness at an object and reflexive directedness of the act at itself come interwoven, there is the intrinsic phenomenology of intentionality. Both intentionality of phenomenology and phenomenology of intentionality present the wholes with mutually pervading and only logically distinguishable parts. The above theses establish balance between phenomenology and intentionality, a balance disrupted in (...) both analytical and continental traditions to which Brentano was a precursor. (shrink)

Gettiered beliefs are those whose agents are subject to the kind of epistemologically significant luck illustrated by Gettier Cases. Provided that knowledge requires ungettiered belief, we can learn something about knowledge by figuring out how luck blocks it in Gettier Cases. After criticizing the most promising of the going approaches to gettiered belief—the Risk of False Belief Approach—, I explain and defend a new approach: the Risk of Misleading Dispositions Approach.Roughly, this view says that a belief is gettiered just in (...) case its unfortunate subject has at best just luckily avoided being disposed by his belief’s actual grounds to believe a wide class of falsehoods about his environment. I then show how this approach undercuts an influential recent argument that knowledge has no more value than certain subsets of its components. (shrink)

The most striking feature of Meinong's theory of intentionality is his thesis that every mental act has its reference‐object “beyond being and non being”. This theory seems, at first, to be a clear example of the so called object‐theory of intentionality, as it introduces special “postulated” entities in the target‐position of the mental act. Closer examination, however, reveals in Meinong's works important elements of the mediator‐theory. Meinong speaks of auxiliary incomplete objects situated “between” the subject and the object of reference (...) and “mediating” the intentional access to the reference‐object. Moreover, even if the object of reference is of the simple nominal form, the mediating structure involves essentially propositional entities . In the paper we attempt to give a set‐theoretical interpretation of Meinong's theory in the frame of which we could eventually do without the incomplete mediating objects. Yet, some general epistemological considerations suggest the indispensability of such incomplete mediating structures. (shrink)

The view that the subject matter of epistemology is the concept of knowledge is faced with the problem that all attempts so far to define that concept are subject to counterexamples. As an alternative, this article argues that the subject matter of epistemology is knowledge itself rather than the concept of knowledge. Moreover, knowledge is not merely a state of mind but rather a certain kind of response to the environment that is essential for survival. In this perspective, the article (...) outlines an answer to four basic questions about knowledge: What is the role of knowledge in human life? What is the relation between knowledge and reality? How is knowledge acquired? Is there any a priori knowledge? (shrink)
