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.

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 outlines a version of instantaneous presentism, according to which the present is a point-like instant, and defends it from two prominent objections. The first one has to do with the difficulty of accounting, from the point of view of instantaneous presentism, for the existence of events that take time, dynamic events, which cannot be confined to a single instant. The second objection is of a Zenonian nature and arises once time is viewed as a continuum that can be subdivided ad infinitum. In response to the first problem, it is argued that the presentist can appeal to past and future instants as long as it is not assumed that there are events that occur at them. Once they are granted, one can then appeal to "past-oriented" and "future-oriented" properties such as *was P at t* (or *will be P at t*), where t is a past or future instant, in order to view dynamic events as occurring at the present instant. In response to the second problem, one must accept the idea that, as a new instant becomes present, there is no preceding instant which is immediately past. There can only be infinitely many past instants with increasingly lower degrees of pastness.

States of affairs involving a non-symmetric relation such as loving are said to have a relational order, something that distinguishes, for instance, Romeo’s loving Juliet from Juliet’s loving Romeo. Relational order can be properly understood by appealing to o-roles, i.e., ontological counterparts of what linguists call thematic roles, e.g., agent, patient, instrument, and the like. This move allows us to meet the appropriate desiderata for a theory of relational order. In contrast, the main theories that try to do without o-roles, proposed by philosophers such as Russell, Hochberg, and Fine, are in trouble with one or another of these desiderata. After discussing some alternatives, it is proposed that o-roles are best viewed as very generic properties characterizable as ways in which objects jointly exemplify a relation. This makes for exemplification relations understood as complex entities having o-roles as building blocks

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.

This original and enticing book provides a fresh, unifying perspective on many old and new logico-philosophical conundrums. Its basic thesis is that many concepts central in ordinary and philosophical discourse are inherently circular and thus cannot be fully understood as long as one remains within the confines of a standard theory of definitions. As an alternative, the authors develop a revision theory of definitions, which allows definitions to be circular without this giving rise to contradiction (but, at worst, to “vacuous” uses of definienda). The theory is applied with varying levels of detail to a circular analysis of concepts as diverse as truth, predication, necessity, physical object, etc. The focus is on truth, and hope is expressed that a deeper understanding of the Liar and related paradoxes has been provided: “We have tried to show that once the circularity of truth is recognized, a great deal of its behavior begins to make sense. In particular, from this viewpoint, the existence of the paradoxes seems as natural as the existence of the eclipses” (p. 142). We think that this hope is fully justified, although some problems remain that future research in this field should take into account.

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.

This paper first discusses how Russell and Hochberg have addressed some phenomena of relatedness, notably relational order, in a similarly ‘positionalist’ way, yet by appealing to different sorts of formal relations: “positions” in Russell's case and “ordering relations” in Hochberg's. After pointing out some shortcomings of both approaches, the paper then proposes an alternative view based on ‘o-roles’, which are, roughly speaking, ontological counterparts of the thematic roles postulated in linguistics. It is argued that o-roles are sort of middle-of-the-road entities in the sense that they have the virtues of positions and those of ordering relations, without having their respective vices. Some tentative ideas on which o-roles should be acknowledged are also put forward

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.
