The Kantian revolution limited the possibility of ontological knowledge, severing subject from thing as is evident in its legacy in both continental and analytic philosophy. Consequently, if a thing cannot be known as it is, the philosophical status of empirical science as a study about existing natural things should be called into question. It could be construed, for instance, that a scientific theory is a construction about something to which the subjective constructor can never have ontological access. But, when empirical (...) scientists develop evidence-based proofs for their theories the assumption of realism usually stands: scientific theories constructed by scientists are actually purported to represent natural entities back to these constructing scientists. Given that there is a danger of philosophy becoming isolated from empirical science, we attempt to bridge the gap between philosophical discourse and science-in-praxis through a recapitulation of Aquinas’ ontological epistemology. Aquinas argued for a clarified realism in which the epistemic is construed as an intersection between the thinking subject and the object. Contrary to naïve realism, then, it will be explicated how Aquinas’ realism was a precursor of “critical realism”, as he discerned the complex interaction of thinking subject and the being of the object as both bearing on the production of knowledge.

If I say that Alice is everything Oscar hopes to be, I seem to be quantifying over properties. That suggestion faces an immediate difficulty, however: though Alice may be wise, she surely is not the property of being wise. This problem can be framed in terms of a substitution failure: if a predicate like ‘happy’ denoted a property, we would expect pairs like ‘Oscar is happy’ and ‘Oscar is the property of being happy’ to be equivalent, which they clearly are (...) not. I argue that a Fregean response that draws a distinction between objects and concepts faces serious difficulties, and that a syntactic solution to the substitution problem likewise fails. I propose to account for the substitution failure by instead distinguishing different ways that expressions can stand for properties: whereas ‘the property of being happy’ refers to a property, ‘happy’ expresses or ascribes that property. I go on to compare this view to proposals made by Wright and Liebesman, and end by drawing out a consequence my proposal has for a debate about the ontological commitments of predicatively quantified sentences.

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.

The Fregean analysis of definite descriptions as referring expressions predicts that copular sentences with definite descriptions in postcopular position are invariably interpreted as identity statements. But as numerous diagnostics show, such sentences are frequently capable of receiving a predicational reading. A uniform Fregean analysis therefore won’t do. Things aren’t that simple, however. I show that descriptions which exhibit the structure [the + N + of + Proper Name] fall into two semantically distinct classes, and that the members of one of (...) these classes of descriptions (those I call “identifying”) pattern with proper names in resisting a predicative reading. I argue that a proposal according to which referring expressions can quite generally undergo a type shift that transforms them into predicates thus fails on grounds of overgeneration. I propose that we can account for the data by instead appealing to two definite determiners: a Fregean determiner ‘the r ’ which forms referring descriptions, and a determiner ‘the p ’ which forms predicative descriptions. I argue that this proposal also correctly predicts that copular sentences with proper names in postcopular position fail to have a predicational reading. I conclude the paper by defending the analysis of names to which I appeal against an alternative view inspired by Burge (J Philos 70(14):425–439, 1973), and suggest a way in which the desired results could be achieved while making do with a single definite article.
