In this paper 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 such entities. 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 to be 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.

In Reinach’s works one finds a very rich ontology of states of affairs. Some of them are positive, some negative. Some of them obtain, some do not. But even the negative and non-obtaining states of affairs are absolutely independent of any mental activity. Now in spite of this claim of the “ontological equality” of positive and negative states of affairs there are, according to Reinach, massive epistemological differences in our cognitive access to them. Positive states of affairs could be directly “extracted” from our experience while to acquire a negative belief we must pass a quite complicated process starting with certain positive beliefs. A possible and reasonable explanation of this discrepancy would be a theory to the effect that these epistemological differences have their basis in the ontology of the entities in question. Our knowledge of the negative states of affairs is essentially dependent on our knowledge of the positive ones precisely because the negative states of affairs are ontologically dependent on the positive ones. Such a theory has been in fact formulated by Roman Ingarden. According to him negative states of affairs supervene on some positive ones and on certain mental acts of the conscious subjects.

The problem of how a concrete individual survives changes of its properties has long divided the philosophical community into ‘enduratists’ and ‘perduratists’. Enduratists take the idea of a surviving individual ontologi-cally seriously. They claim that many objects we encounter in our every-day (and for that matter also scientific) life endure in time, which means that these entities are wholly present at any time at which they exist. For those who are in principle happy with the conceptual framework of our ‘everyday’ or ‘folk’ ontology it is common to assume that such things as human beings, animals, and plants are endurants in this sense, and the most famous articulation of this view is to be found in Aristotle’s concept of substance. Enduring entities are to be contrasted with perdurants, such as a life of a human being or a process of growing of a plant. Think of the process of writing this very paper. The beginning of the writing, the actual phase of it and the final completion of the paper are not points at which the process of writing could be wholly present. Rather they constitute phases or parts of the process in question. This means that perduring entities have a temporal dimension whereas enduring ones do not. Most of us are prepared to accept that in the world around us there are many entities of this kind, but perdu-ratists try to defend a far stronger thesis. They claim that in fact there are only perdurants. In our everyday language it is equally common to speak of enduring objects and enduring states. But it was the first idiom which mainly attracted philosophers’ attention. Yet in this paper I want to concentrate on the sec-ond figure of speech. I will investigate, whether it is ontologically legiti-mate to distinguish between enduratist and perduratist perspectives with respect to states.

Résumé -/- Dans son premier livre (Philosophie de l’arithmétique 1891), Husserl élabore une très intéressante philosophie des mathématiques. Les concepts mathématiques sont interprétés comme des concepts de « deuxième ordre » auxquels on accède par une réflexion sur nos opérations mentales de numération. Il s’ensuit que la vérité de la proposition : « il y a trois pommes sur la table » ne consiste pas dans une relation mythique quelconque avec la réalité extérieure au psychique (où le nombre trois doit être exemplifié de quelque manière), mais bien dans le fait que les pommes sur la table peuvent être dénombrées correctement en tant qu’elles sont au nombre de trois. Nous avons affaire ici à une position « antiréaliste » fondant la vérité mathématique non pas dans un monde platonicien, mais bien sur le concept de rectitude de nos opérations formelles. -/- Abstract -/- In his first book (Philosophy of Arithmetic 1891) Husserl develops a very interesting philosophy of mathematics. Mathematical concepts are interpreted as « second order » concepts gained by reflection on our mental operations of counting. Accordingly the truth of the proposition « There are three apples on the table » consists not in any mythical relation to the extra-mental reality (where the number three should be somehow exemplified), but rather in the fact that the apples on the table can be correctly counted as three. We have here an « anti-realist » position grounding the mathematical truth not in platonic realms, but rather in the concept of correctness of our formal operations.

The point of departure for Anton Marty's theory of intentionality is Franz Brentano's ontology of intentionality as outlined in the unpublished manuscript of his logic-lectures from the second half of the 1880's. This rich ontology comprises immanent objects, immanent propositional contents and states of affairs. The late Marty rejects all immanent entities in Brentano's sense and explains intentionality in terms of counterfactualconditionals.However,contraryto the late Brentano,he insists on the indispensability of the category of states of affairs. Consequently Marty can formulate a realistic theory of truth, while Brentano holds an epistemic theory of truth.
