For C.S. Peirce, who had a well‐known influence on many aspects of Ramsey's thought, pragmatism was viewed as inseparable from realism. The aim of this paper is to challenge the view according to which Ramsey's reflexions on universals are of a mere linguistic and logical nature. Not only is this view controversial, but it may be argued that some elements in Ramsey's analyses suggest a possibly realist answer to the problem of universals. By drawing comparisons with Peirce's own position, it (...) is suggested that Ramsey's views might not be inconsistent with many aspects of Peirce's scholastic and even Scotistic version of realism.

ABSTRACTIn ‘Universals’, Ramsey declares that we do not, and cannot, know the forms of atomic propositions. A year later, in a symposium with Braithwaite and Joseph, he announces a change of mind: atomic propositions may, after all, be discoverable by analysis. It is clear from the 1926 paper that Ramsey intends this to be a revision of the 1925 claim. Puzzlingly, however, Ramsey does not mention analysis in 1925. My task in this article is to provide a justification for that (...) change of mind. My argument consists of two parts. I first show what relation holds between the negative 1925 assertion and the more positive 1926 assertion which allows us to read the latter claim as a retraction of the former, as Ramsey appears to have intended it. Then I shall argue that the retraction of the 1925 claim is forced upon Ramsey by reflection on the fact that three theses, all of which he held in or around the relevant period, are, rather surprisingly, revealed to be inconsistent.

Is the assumption of a fundamental distinction between particulars and universals another unsupported dogma of metaphysics? F. P. Ramsey famously rejected the particular – universal distinction but neglected to consider the many different conceptions of the distinction that have been advanced. As a contribution to the piecemeal investigation of this issue three interrelated conceptions of the particular – universal distinction are examined: universals, by contrast to particulars, are unigrade; particulars are related to universals by an asymmetric tie of exemplification; universals (...) are incomplete whereas particulars are complete. It is argued that these conceptions are wanting in several respects. Sometimes they fail to mark a significant division amongst entities. Sometimes they make substantial demands upon the shape of reality; once these demands are understood aright it is no longer obvious that the distinction merits our acceptance. The case is made via a discussion of the possibility of multigrade universals. (shrink)

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

Peter Geach proposed a substitutional construal of quantification over thirty years ago. It is not standardly substitutional since it is not tied to those substitution instances currently available to us; rather, it is pegged to possible substitution instances. We argue that (i) quantification over the real numbers can be construed substitutionally following Geach's idea; (ii) a price to be paid, if it is that, is intuitionism; (iii) quantification, thus conceived, does not in itself relieve us of ontological commitment to real (...) numbers.

According to the broadly Aristotelian distinction between universals and particulars, all and only the former are capable of whole multiple location. The present essay defends this distinction against four putative counterexamples. The first two, extended simple material objects and enduring time-traveling self-meeters, putatively are wholly multiply locatable, but not universals. The second two, unique properties of point-sized entities and Platonic (i.e., not spatiotemporally located) universals, putatively are universals, but not wholly multiply locatable. The defensive strategy is to resist certain presuppositions (...) underlying the examples. (shrink)

One might well wonder—is there a category under which every thing falls? Offering an informative account of such a category is no easy task. For nothing would distinguish things that fall under it from those that don’t—there being, after all, none of the latter. It seems hard, then, to say much about any fully general category; and it would appear to do no carving or categorizing or dividing at all. Nonetheless there are candidates for such a fully general office, including (...) thing, being, entity, item, existent, and—especially—object.[ It is not obvious that there is any fully general category (whether object or otherwise). Accordingly, not all accounts of object assign it to a fully general category, instead allowing that there are non-objects. On those views, object does indeed divide. Accounts of object, then, differ with respect to whether there are non-objects. And this is not the only fault line. Other dimensions of difference include what objects there are and what objects are. Accordingly, this entry will survey three broad questions about the category object: What, if any, is its contrast or complement? What is its extension? What is its nature? (shrink)

Frank Plumpton Ramsey (1903–30) made seminal contributions to philosophy, mathematics and economics. Whilst he was acknowledged as a genius by his contemporaries, some of his most important ideas were not appreciated until decades later; now better appreciated, they continue to bear an influence upon contemporary philosophy. His historic significance was to usher in a new phase of analytic philosophy, which initially built upon the logical atomist doctrines of Bertrand Russell and Ludwig Wittgenstein, raising their ideas to a new level of (...) sophistication, but ultimately he became their successor rather than remain a mere acolyte.

The answer of Lowe to Ramsey’s argument against the distinction universal vs. indivi- dual: At the beginning of this article Ramsey’s argumentation against universal‐particular distinction is presented. It is based on the assumption that this division requires another one: namely, subject‐predicate distinction. This argumentation was a starting point for Lowe, who does not respect the aforementioned assumption. In his theory, there are not two but four categories, namely: substantial universals, non‐substantial universals, substantial particulars, and non‐substantial particulars. Two of these categories (...) are categories of universals; the other two are categories of particulars. Lowe tries to de ne categories in an ontological way, that is, with essential use of ontological notions. These notions are rigid and non‐rigid existential de‐ pendence, which are themselves de ned in terms of necessity and existence. The contribution of this paper is an analysis of Lowe’s solution. In the rst place, it is con onted with Ramsey remarks. Then other objections are considered. Some of them do not respect the very idea of autonomous ‘ontological way’ in philosophy. Others concern Lowe’s particular version of it. Possible answers to all of these objections are presented, such that Lowe’s theory is defended. However, there is no ultimate conclusion here. In the author’s opinion autonomy and the value of ontology cannot be shown om a purely external position. We should rst assume that this discipline does make sense and then explore its virtues by using its notions. (shrink)

I reassess the famous arguments of Frank Plumpton Ramsey (1925) against the tenability of the distinction between particulars and universals and discuss their recent elaboration by Fraser MacBride. I argue that Ramsey’s argument is ambiguous between kinds and properties and that his sceptical worries can be resolved once this distinction is taken into account. A crucial role in this dissolution is a notion of what is essential to a property. I close by some epistemological considerations.
