The thesis that there can be vague objects is the thesis that there can be identity statements which are indeterminate in truth-value (i.e., neither true nor false) as a result of vagueness (as opposed, e.g., to reference-failure), "the singular terms of which do not have their references fixed by vague descriptive means". (if this is "not" what is meant by the thesis that there can be vague objects, it is not clear what "is" meant by it.) the possibility of vague objects should not be taken, in itself, to imply the more radical thesis that the identity relation can be one of "degree". one can hold that the concept of degrees of identity is absurd (how can one thing be more or less identical to another?) "and" that indeterminacy in identity is possible; hence, any incoherence in the idea of degrees of identity does not thereby undermine the idea of indeterminate identity

This note criticizes Andrew Brennan's attempt to defend best?candidate theories of the identity of artefacts over time against certain now familiar objections. Adoption of a mereological conception of individuals does not, in itself, provide the means for a satisfactory response to objections of Wiggins and Noonan (some of which are anyway ill?focused). The way forward consists in recognizing that the consequences of best?candidate theories which have been thought objectionable (in particular, commitment to the extrinsicness of identity) do not violate the necessity of identity and imply ? what anyway ought to seem unexceptionable ? that a predicate such as ?constituting the ship which is the Ship of Theseus? does not denote a genuine property of the hunk of matter of which the predicate is true. Once these consequences have been clearly mapped out, the best?candidate theorist's commitment to the extrinsicness of identity does not appear absurd

This essay examines some aspects of the early history of the vitalism/mechanism controversies by examining the work of Nehemiah Grew in relation to that of Henry More , Francis Glisson and the more mechanistically inclined members of the Royal Society. I compliment and critically comment on John Henry's exploration of active principles in pre-Newtonian mechanist thought. The postulation of ‘active matter’ can be seen as an important support for the new experimental philosophy, but it has theological drawbacks, allowing for a self-sufficient nature relatively independent of God. Grew resists this view and, like Henry More, advocates the need for a vital principle to direct material nature towards its ends. I illustrate the connection Grew sees between teleology and vitalism and the paper closes with Pierre Bayle's reaction to Grew's attempt to support his religious commitments by appeal to vital principles.So many Arts, hath the Divine Wisdom put together; onlyfor the hull and tackle, of a sensible and Thinking creature.Nehemiah Grew, Cosmologia

David Chalmers claims that the logical possibility of ‘zombie worlds’ — worlds physically indiscernible from the actual world, but that lack consciousness — reveal that consciousness is a distinct fact, or property, in addition to the physical facts or properties.The ‘existence’ or possibility of Zombie worlds violates the physicalist demand that consciousness logically supervene upon the physical. On the assumption that the logical supervenience of consciousness upon the physical is, indeed, a necessary entailment of physicalism, the existence of zombie worlds implies the falsity of physicalism. How do we determine the logical possibility of zombie worlds? By conceptual analysis of the concepts involved, keeping empirical facts in mind.

Resumo Neste texto, o autor concentra-se em dois artigos históricos: o de Max Black “Why cannot an effect precede its cause”? e o de Michael Dummett “Bringing about the Past”. O autor irá mostrar onde falha o “bilking argument” de Black, contra a possibilidade da causalidade invertida. Por conseguinte, o autor irá concordar com Dummett, na possibilidade de um agente actuar a fim de que algo possa ocorrer no passado, contudo, discordando da argumentação de Dummett face a um desafio céptico, que tenta mostrar a inutilidade de afectar o passado. Palavras-chave : Black, causalidade invertida, Dummett, razões, tempoIn this discussion I focus on two classic articles: Max Black’s ‘Why cannot an effect precede its cause?’ and Michael Dummett’s ‘Bringing about the Past’. I argue that Black’s bilking argument against the possibility of backwards causation fails. I agree with Dummett that the idea of an agent acting in order that something should have happened in the past is not absurd, but I disagree with Dummett’s response to a sceptical challenge which attempts to show that it is pointless to attempt to affect the past.
