Berkeley's idealism consists of the following claims. Objects such as chairs, apples, mountains, and our bodies are combinations of sensible qualities. Sensible qualities and combinations of such are ideas or sensations. In the philosophical sense of ‘substance’ there is no such entity as a substance. There are minds which perceive and will: When a mind perceives it has sensations or ideas; and when a mind wills it produces or causes sensations or ideas. These claims are grounded in the ontological and (...) epistemological framework of assumptions, distinctions and arguments informing Berkeley's doctrine thatesse est percipi aut percipere.The purpose of this paper is to explore and expose the main features of that framework.What is the ontological force and import on Berkeley's claim thatesse est percipi?One influential recent suggestion1 is this: Berkeley holds that (1) material substances do not exist, (2) the analysis of sensible things yields nothing but sensible qualities, (3) minds are mental substances and (4) no sensible quality or collection of sensible qualities can exist without inhering in some substance.

The main aim of this paper is to explore why it is so important for Hume to defi ne ‘cause’ as he does. This will shed light on the signifi cance of the natural/philosophical relation (hereafter NPR) distinction in the Treatise. Hume's use of the NPR distinction allows him to dismiss on general grounds conceptions of causation at odds with his own. In particular, it allows him to avoid having to engage in detailed re-interpretation of potentially confl icting theories formulated (...) by natural philosophers. Moreover, it provides an instance of the normative nature of Hume's “science of man.” The paper argues that the NPR distinction - in conjunction with the so-called copy principle - is meant to undercut appeals to the authority of theories not founded on Hume's “principles.” In order to illustrate its claims about Hume, this essay explores some aspects of Newton's natural philosophy. Finally, this paper resolves a long-standing interpretive problem: how to reconcile Hume's two “defi nitions” of causation in the Treatise. (shrink)

The paper considers recent proposals by Armstrong, Dretske, and Tooley that revive the view that statements of laws of nature are grounded by the existence of higher order facts relating universals. Several objections to such a view are raised and an alternative analysis, recognizing general facts, is considered. Such an alternative is shown to meet a number of the objections raised against the appeal to higher order facts and it is also related to views of Hume and Wittgenstein. Further objections (...) are then raised to all the non-Humean "realist" attempts to provide special facts to ground the laws of nature. (shrink)

Exemplification can be found in ontologies from the ancient world, such as those of Plato and Aristotle, and more recent ontologies, in particular those that take what exists to be determined by the empiricist’s Principle of Acquaintance. This study examines some of the ways in which exemplification takes different forms in these different ontologies. Exemplification has also been criticized as an ontological category. This paper examines a number of these criticisms, to see the extent to which they are viable.

The paper claims that Hume ’s philosophy contains an ontology, i.e. an abstract exhaustive classification of what there is. It is argued that Hume believes in the existence of a mind-independent world, and that he has a classification of mind-related entities that contains four top genera: perception, faculty, principle and relation. His ontology is meant to be in conformity with his philosophy of language and epistemology, and vice versa. Therefore, crucial to Hume ’s ontology of mind-independent entities is his notion (...) of ‘supposing relative ideas ’. Entities that are referred to by means of ordinary ideas can be truly classified, whereas entities that are referred to by means of relative ideas can only be hinted at. When Hume ’s ontology is highlighted and systematised, his notion ‘the faculty of imagination’ becomes highly problematic. However, the exposition also makes it clear that Hume deserves the honorary title: the first cognitive scientist. (shrink)
