In this paper I will address the question of rationalizing mental causation which is involved in the processes of epistemic justification. The main problem concerning mental causation consists in the apparent incompatibility of the three following claims: (i) the subject's mental states (in particular his belief states) are realized by neural states of the subject's brain; (ii) the justifying character of belief transition consists in the fact that there are certain broadly logical relations between the contents of the relevant beliefs; and (iii) all generations of neural states are, at bottom, governed by the purely physical laws. I try to reconciliate the physical necessity of the neural states generation with the logical rationality of the belief transition. Surprisingly enough, it will turn out that, in a sense, each thinking subject is logically perfect. However, in another sense we are exactly as fallible and irrational as our common-sense tells us.

I propose a certain classification of entities which are introduced in various theories of intentionality under the label ‘intentional objects’. Franz Brentano’s immanent objects, Alexius Meinong’s entities ‘beyond being and non-being’, or Roman Ingarden’s purely intentional objects can serve as examples of suchentities. What they all have in common is that they have been introduced in order to extensionalise the so called ‘intentional contexts’ (‘intentional’ with ‘t’). But not all entities which function this way deserve the name of intentional objects. In particular, neither Frege’s senses nor mental contents of the early Husserl are tobe classified as intentional objects in my sense. Roughly speaking, to be properly called ‘an intentional object’ a postulated entity must be supposed to function as a quasi-target of the subject’s intention. In other words: intentional objects are supposed to stand ‘before the subject’s mind’, so that they, in a sense, ‘replace’ the common sense objects of reference. It turns out that the intentional objects that were introduced in the history of philosophy make up groups which,from the ontological point of view, are very heterogeneous. Nevertheless it is possible to formulate certain systematic criteria of classifying them.

Ontology is doubtless the most important part of Roman Ingarden’s (1893-1970) philosophy. Contrary to Husserl, Ingarden always believed that any serious philosophical investigation must involve an ontological basis and he tried to formulate a solid ontological framework for his philosophy. There are several reasons why this ontology deserves our attention. For those who are interested in Husserl’s transcendental phenomenology, Ingarden’s ontology could be treated as an ingenious attempt to analyse the conceptual structure and hidden ontological assumptions of Husserl’s transcendental idealism. For those who want to understand the immanent dialectics of the post-Brentanian development of the ontology of intentionality, Ingarden’s conception of the purely intentional object could be a very valuable tool. But Ingarden’s ontology has also independent value, and hence it is also interesting for those who pursue ontology for its own sake. In this paper, I will investigate the basic scheme of Ingarden’s ontology, including pure qualities, individual real objects, purely intentional objects and ideas. This schema will prove to be in many aspects generated by his phenomenological, i.e. descriptive and anti-reductionist, ideology.

The book is an analytic exposition of Brentano's early theory of intentionality. In spite of the immense influence of this theory it is the first separate monograph on this topic. The book is based in great part on the unpublished manuscripts where one can find substantially better articulated formulations then those expressed in the already published `standard' works. Our analysis concentrates mainly on the ontological and epistemological problems of Brentano's immanent object. We highlight an interesting ambiguity of this concept and try to outline the inner logic of its evolution. It turns out that Brentano's early philosophy of intentionality should be conceived not as a single, well defined theory but rather as a bundle of kindred but not always fully consistent and sometimes even competing ideas. Primary audience for the work are philosophers interested in Brentano's philosophy, theory of intentionality and its epistemology and ontology, phenomenologists and cognitive scientists. Das Buch bietet eine analytische Darstellung von Brentanos früher Theorie der Intentionalität. Trotz der großen historischen Bedeutung dieser Theorie bildet es die erste Monographie zu diesem Thema. Das Buch basiert zum größten Teil auf den unveröffentlichten Manuskripten, in denen man die Formulierungen findet, die viel besser artikuliert sind als jene, die in den publizierten Standard-Werken Brentanos zu finden sind. Unsere Analyse konzentriert sich in erster Linie auf die ontologischen und epistemischen Probleme des Brentanoschen immanenten Objekts. Wir besprechen eine interessante Mehrdeutigkeit dieses Begriffs und skizzieren die innere Logik seiner Entwicklung. Es stellt sich heraus, daß die frühe Philosophie der Intentionalität Brentanos nicht als eine einheitliche, eindeutig bestimmte Theorie, sondern eher als ein Bündel von verwandten, jedoch nicht immer völlig koherenten und manchmal sogar konkurrierenden Ideen interpretiert werden soll. Das Buch wendet sich in erster Linie an die Philosophen, die sich für die Philosophie Brentanos, für die österreichische Philosophie, für die Theorie der Intentionalität und ihre Epistemologie und Ontologie interessieren. Es wird ferner auch für die Phänomenologen und die Forscher im Bereich der cognitive science interessant sein.
