Added by: Jamie CollinAbstract: The distinction between a type and its tokens is a useful metaphysical distinction. In §1 it is explained what it is, and what it is not. Its importance and wide applicability in linguistics, philosophy, science and everyday life are briefly surveyed in §2. Whether types are universals is discussed in §3. §4 discusses some other suggestions for what types are, both generally and specifically. Is a type the sets of its tokens? What exactly is a word, a symphony, a species? §5 asks what a token is. §6 considers the relation between types and their tokens. Do the type and all its tokens share the same properties? Must all the tokens be alike in some or all respects? §7 explains some problems for the view that types exist, and some problems for the view that they don't. §8 elucidates a distinction often confused with the type-token distinction, that between a type (or token) and an occurrence of it. It also discusses some problems that occurrences might be thought to give rise to, and one way to resolve them.Comment: Would be useful in advanced undergraduate or postgraduate courses on metaphysics or philosophy of language. Though Wetzel's goal is, ultimately, to address metaphysical questions about the existence of types, the type/token distinction crops up in many areas of philosophy, and this would be an excellent reference point for explaining what the distinction amounts to. Though the entry is on the less-discussed topic of types, it is also relevant to the more-discussed topic of universals. This would be very suitable for an undergraduate course in metaphysics or philosophical logic. It would also work well at the beginning of a masters course in metaphysics or philosophical logic. This is a particularly good alternative to Wetzel's book "Types and Tokens" if that is unavailable at your institution.

Added by: Laura Jimenez, Contributed by: Pauline PhemisterAbstract: This new introduction to a philosophical classic draws on the reinterpretations of Descartes' thought of the past twenty-five years. Catherine Wilson examines the arguments of Descartes' famous Meditations, revealing how he constructs a theory of the mind, body, nature, and God from a premise of radical uncertainty. She discusses in detail the historical context of Descartes' writings and their relationship to early modern science, and at the same time she introduces concepts and problems that define the philosophical enterprise as it is understood today.Comment: Following closely the text of the Meditations and meant to be read alongside them, this survey is accessible to readers with no previous background in philosophy. It is well-suited to university-level courses on Descartes, but can also be read with profit by students in other disciplines.

Added by: Nick NovelliAbstract: Deep theorizing about possibility requires theorizing about possible objects. One popular approach regards the notion of a possible object as intertwined with the notion of a possible world. There are two widely discussed types of theory concerning the nature of possible worlds: actualist representationism and possibilist realism. They support two opposing views about possible objects. Examination of the ways in which they do so reveals difficulties on both sides. There is another popular approach, which has been influenced by the philosophy of Alexius Meinong. The Meinongian approach is relevant to theorizing about possible objects because it attempts to construct a general theory of objects other than ordinary concrete existing objects. Independently of the debate about the nature of possible worlds or about Meinongianism, it is not always as straightforward as it may at first appear to determine whether putative possible objects are indeed possible. Another category of object similar to that of a possible object is the category of a fictional object. Although initially attractive, the idea that fictional objects are possible objects should not be accepted blindly. An important instance of theoretical usefulness of possible objects is their central role in the validation of two controversial theorems of a simple quantified modal logic.Comment: A good introduction to the different positions on possible objects, including their impact on modal logic. Would be a good starting point for a discussion of these issues in a metaphysics course, or as an introduction to these positions for an ontology of art/fiction course.
