La connaissance métaphysique est accessible et nous possédons un tel type de connaissance. Il faut pratiquer la métaphysique de manière directe, sans passer par des considérations de philosophie du langage ou de l'esprit. Les deux principales critiques de la métaphysique sont : le naturalisme évolutionniste et le kantisme. Le naturalisme est incohérent car il nie la possibilité défaire des hypothèses métaphysiques et pourtant il repose sur de telles hypothèses. Kant également ne va pas au bout de son projet, car on ne peut éviter la question du contenu des pensées, une fois qu'on a réduit la métaphysique à une théorie de la connaissance. L'examen des arguments de Barcan-Kripke confirme la possibilité d'une argumentation métaphysique et l'impossibilité d'y échapper. Metaphysical knowledge is accessible and indeed, we have such a knowledge. Metaphysics shoud be done directly, without starting with considerations of philosophy of language or philosophy of mind. The two main critiques of metaphysics are evolutionary naturalism and Kantianism. Naturalism is inconsistent because it denies any possibility to make metaphysical hypotheses, but it hinges upon such hypotheses. Kant is also inconsistent because one cannot avoid the question of the content of thoughts once metaphysics has been reduced to epistemology. A scrutiny of the arguments by Barcan and Kripke confirms the possibility of a purely metaphysical argumentation and the impossibility to do without it.

It has long been debated whether objects are ‘sortally’ individuated. This paper begins by clarifying some of the key terms in play—in particular, ‘sortal’, ‘individuation’, and ‘object’. The term ‘individuation’ is taken to have both a cognitive and a metaphysical sense, in the former denoting the singling out of an object in thought and in the latter a determination relation between entities. ‘Sortalism’ is defined as the doctrine that only as falling under some specific sortal concept can an object be successfully singled out in thought. It is argued that such a view is too strong, but that a weaker one, ‘categorialism’, can be defended, this implying that a thinker cannot successfully single out an object in thought without having at least an implicit grasp of the criterion of identity that the object satisfies.

Locke notoriously included number amongst the primary qualities of bodies and was roundly criticized for doing so by Berkeley. Frege echoed some of Berkeley's criticisms in attacking the idea that ‘Number is a property of external things’, while defending his own view that number is a property of concepts. In the present paper, Locke's view is defended against the objections of Berkeley and Frege, and Frege's alternative view of number is criticized. More precisely, it is argued that numbers are assignable to pluralities of individuals. However, it is also argued that Locke went too far in asserting that ‘Number applies itself to ... everything that either doth exist, or can be imagined’.

John Locke is widely acknowledged as the most important figure in the history of English philosophy and _An Essay Concerning Human Understanding_ is his greatest intellectual work, emphasising the importance of experience for the formation of knowledge. The _Routledge Guidebook to Locke’s Essay Concerning Human Understanding_ introduces the major themes of Locke’s great book and serves as a companion to this key work, examining: The context of Locke’s work and the background to his writing Each part of the text in relation to its goals, meaning and impact The reception of the book when it was first seen by the world The relevance of Locke’s work to philosophy today, its legacy and influence With further reading suggested throughout, this text follows Locke’s original work closely, making it essential reading for all students of philosophy, and all those wishing to get to grips with this classic work.
