A version of Bradley's regress can be endorsed in an effort to address the problem of the unity of states of affairs or facts, thereby arriving at a doctrine that I have called fact infinitism. A consequence of it is the denial of the thesis, WF, that all chains of ontological dependence are well‐founded or grounded. Cameron has recently rejected fact infinitism by arguing that WF, albeit not necessarily true, is however contingently true. Here fact infinitism is supported by showing that Cameron's argument for the contingent truth of WF is unsuccessful.

Dynamic events such as a rolling ball moving from one place to another involve change and time intervals and thus presumably successions of static events occurring one after the other, e.g., the ball’s being at a certain place and then at another place during the interval in question. When dynamic events are experienced they should count as present and thus as existent from a presentist point of view. But this seems to imply the existence of the static events involved in them. This in turn seems to imply that there exist past and perhaps even future static events. Therefore, there is a problem for presentism. A possible way out for the presentist is proposed, based on allowing for time-indexed past-oriented and future-oriented properties. One may raise objections regarding the ontological status of these properties and the commitment to past and future objects and times that they seem to bring with them, but these objections can be put to rest.

This paper embeds a theory of proper names in a general approach to singular reference based on type‐free property theory. It is proposed that a proper name “N” is a sortal common noun whose meaning is essentially tied to the linguistic type “N”. Moreover, “N” can be singularly referring insofar as it is elliptical for a definite description of the form the “N” Following Montague, the meaning of a definite description is taken to be a property of properties. The proposed theory fulfils the major desiderata stemming from Kripke's works on proper names.

This paper examines the challenge that the argument known as "Bradley's regress" poses to the friends of states of affairs (facts), in its requesting an explanation of the existence of a fact as a unitary whole in addition to its constituents. All the main theoretical options, short of denying that there are facts, are considered. It is argued that only two of them are viable, namely a "Brute fact approach", according to which the existence of a fact cannot be explained with the typical tools of ontologists, and "Fact infinitism", according to which, for any given fact, one should posit for explanatory purposes an infinite number of distinct states of affairs involving exemplification relations of higher and higher levels. Fact infinitism is defended against various objections and it is suggested that it should be preferred to the brute fact approach by those who are not too shy in vindicating for ontology a role, alongside with the empirical sciences, in the task of postulating entities in order to achieve explanations.

I assume that the task of natural language semantics is to provide an unambiguous logical language into which natural language can be translated in such a way that the translating expressions display a structure which is isomorphic to the meaning of the translated expressions. Since language is a means of thinking and communicating mental contents, the meanings of singular terms cannot be the individuals of the substratist tradition, because such individuals are not cognizable entities. Thus I propose that the logical language be based on Castaneda's guise theory, according to which singular terms always denote guises, i.e., roughly, bundles of properties. This, I argue, would result in a semantics which is in accordance with projects such as Lakoff's natural logic or Fodor's methodological solipsism. ;I first propose a formal system, GCC, which tries to be as faithful as possible to Castaneda's informal presentation of guise theory. It is therefore characterized by different forms of predication and a distinction between a level of property composition and a level of proposition composition. Such a distinction is dropped in a second system, GF, which presents a more traditional Fregean representation of predication. Yet, GF endorses essential assumptions of guise theory such as the existence of different sameness relations that can provide various interpretations for the English "is". I claim that GF provides more theoretical simplicity than GCC. ;Finally, I show the fruitfulness of the present approach by applying GF to a vast collection of linguistico-philosophical puzzles which includes but is not restricted to those that guise theory was originally designed to address: various versions of Frege's paradox, the paradox of analysis, Quine's puzzle on the number of planets, issues of reidentification and intentional identity, the anaphoric "it" of sentences such as "the lizard's tail fell off but then it grew back," problems connected with the use of "knowing-who ," proper names, indexicals and demonstratives

There have been attempts to derive anti-haeccetistic conclusions from the fact that quantum mechanics (QM) appeals to non-standard statistics. Since in fact QM acknowledges two kinds of such statistics, Bose-Einstein and Fermi-Dirac, I argue that we could in the same vein derive the sharper anti-haeccetistic conclusion that bosons are bundles of tropes and fermions are bundles of universals. Moreover, since standard statistics is still appropriate at the macrolevel, we could also venture to say that no anti-haecceitistic conclusion is warranted for ordinary objects, which could then tentatively be identified with substrates. In contrast to this, however, there has been so far no acknowledgement of the possibility of inclusivism, according to which ontological accounts of particulars as widely different as those can possibly coexist in one world picture. The success of the different statistics in physics at least calls for a revision in this respect.

This paper builds on Lakoff’s and Johnson’s theory of metaphorical concepts to propose that our conception of truth as correspondence with reality is metaphorically based on our conception of perceptual fields. In particular, it is argued that parts of reality, as metaphorically understood in terms of parts of perceptual fields, can play the role of objective truth-makers for sentences with empirical content; for instance, they meet the constraints on correspondence put forward by Barry Smith. Finally, Richard Boyd’s account of the function of metaphor in science is utilized to ground the nonfictional and referential status of truth-maker and related notions.

There are many data suggesting that we should acknowledge fictional entities in our ontological inventory, in spite of the paraphrasing strategies that Russell’s theory of descriptions can offer. Thus the realist attitude toward fictional entities of Meinongian and artifactualist accounts may seem well-motivated. Yet, these approaches infringe the Russellian “robust sense of reality.” A different realist account is proposed here, one that is compatible with the Russellian “robust sense of reality” in that it identifies fictional entities with denoting concepts, understood as properties of properties.

In line with much current literature, Bradley’s regress is here discussed as an argument that casts doubt on the existence of states of affairs or facts, understood as complex entities working as truthmakers for true sentences or propositions. One should distinguish two versions of Bradley’s regress, which stem from two different tentative explanations of the unity of states of affairs. The first version actually shows that the corresponding explanation is incoherent; the second one merely points to some prima facie implausible consequences of the explanation it stems from, e.g., that there are infinite explanatory chains and that, for any given fact, there are infinitely many facts involving exemplification relations of increasing levels. But these consequences can be swal- lowed after all, thereby leading to the acceptance of a doctrine which may be called fact infinitism, a doctrine adumbrated in a well-known discussion of relations by Meinong.

This paper presents a type-free property-theoretic system in the spirit of a framework proposed by Menzel and then supplements it with a theory of truth and exemplification. The notions of a truth-relevantly complex (simple) sentence and of a truth-relevant subsentence are introduced and then used in order to motivate the proposed theory. Finally, it is shown how the theory avoids Russell's paradox and similar problems. Some potential applications to the foundations of mathematics and to natural language semantics are sketched in the introduction.

Analyses, in the simplest form assertions that aim to capture an intimate link between two concepts, are viewed since Russell's theory of definite descriptions as analyzing descriptions. Analysis therefore has to obey the laws governing definitions including some form of a Substitutivity Principle (SP). Once (SP) is accepted the road to the paradox of analysis is open. Popular reactions to the paradox involve the fundamental assumption (SV) that sentences differing only in containing an analysandum resp. an analysans express the same proposition, because analysandum and analysans are the same entity. Following suggestions of Gupta and Belnap it is argued that (SV) should be rejected.
