R.M. Sainsbury's account of reference has many compelling and attractive features. But it has the undesirable consequence that sentences of the form "x is thinking about y" can never be true when y is replaced by a non-referring term. Of the two obvious ways to deal with this problem within Sainsbury's framework, I reject one and endorse the other. This endorsement is also within the spirit of Sainsbury's account of reference. /// La explicación que ofrece R.M. Sainsbury de la referencia tiene muchas características convincentes y atractivas, pero tiene la consecuencia indeseable de que oraciones de la forma "x está pensando acerca de y" nunca pueden ser verdaderas cuando se reemplaza y con un término no referencial. De las dos maneras obvias de tratar este problema dentro del marco teórico de Sainsbury, rechazo una y acepto la otra. Aceptar esta última también cae dentro del espíritu de la explicación de la referencia ofrecida por Sainsbury.

John D. Caputo’s book is one in a new series from Penguin called “Philosophy in Transit”. The “transit” theme has a number of dimensions: the publisher announces that the authors use “various modes of transportation as their starting point”, and the books will use this idea to represent some aspect of the current state of philosophy itself (a leading metaphor of Caputo’s book is that truth is perpetually “on the go”). Furthermore, the publisher’s description of these books as “commute-length” indicates when and where they expect people to read them. Future volumes – by Barry Dainton on “self”, Susan Neiman on “why grow up?” and the ubiquitous Slavoj Zizek on “event” – are forthcoming.

The currently standard philosophical conception of existence makes a connection between three things: certain ways of talking about existence and being in natural language; certain natural language idioms of quantification; and the formal representation of these in logical languages. Thus a claim like ‘Prime numbers exist’ is treated as equivalent to ‘There is at least one prime number’ and this is in turn equivalent to ‘Some thing is a prime number’. The verb ‘exist’, the verb phrase ‘there is’ and the quantifier ‘some’ are treated as all playing similar roles, and these roles are made explicit in the standard common formalization of all three sentences by a single formula of first-order logic: ‘(∃ x )[P( x ) & N( x )]’, where ‘P( x )’ abbreviates ‘ x is prime’ and ‘N( x )’ abbreviates ‘ x is a number’. The logical quantifier ‘∃’ accordingly symbolizes in context the role played by the English words ‘exists’, ‘some’ and ‘there is’

Qu’est-ce que le problème de la perception au sens strictement philosophique ? On affirme ici que c’est le conflit entre la nature de l’expérience perceptuelle telle qu’elle nous paraît intuitivement et certaines possibilités qui sont implicites justement dans l’idée d’expérience : les possibilités d’illusion et d’hallucination. L’expérience perceptuelle semble être un rapport à ses objets, une sorte d’«ouverture au monde» qui implique une conscience directe des objets existants et de leurs propriétés. Mais si l’on peut avoir une expérience perceptuelle d’un objet qui n’est pas là – hallucination d’un objet -, il semble bien que l’expérience perceptuelle ne saurait être essentiellement un tel rapport. Et c’est là le problème philosophique fondamental de la perception. Différentes théories philosophiques de la perception des XXe et XXIe siècles peuvent être considérées comme autant de réponses à ce problème

‘Poor Bertie’ Beatrice Webb wrote after receiving a visit from Bertrand Russell in 1931, ‘he has made a mess of his life and he knows it’. In the 1931 version of his Autobiography, Russell himself seemed to share Webb’s estimate of his achievements. Emotionally, intellectually and politically, he wrote, his life had been a failure. This sense of failure pervades the second volume of Ray Monk’s engrossing and insightful biography. At its heart is the failure of Russell’s marriages to Dora Black and Patricia (Peter) Spence, his poor relationships with his children John and Kate, and the decline in his reputation as a philosopher. Russell, who had changed the direction of philosophy irrevocably, was in later years unable to find permanent academic employment in Britain, ousted from his professorship at the City College of New York because of his views on sex and marriage, and was reduced to giving nonspecialist lectures at a foundation established by the Philadelphia philanthropist Albert C. Barnes. Eventually in 1944 he returned to Cambridge, but by then the philosophical world was in the grip of Ludwig Wittgenstein’s ideas, and Russell was largely ignored.

Was ist das distinktive philosophische Problem der Perzeption? Hier wird behauptet, dass es der Konflikt zwischen der Natur der perzeptuellen Erfahrung ist, wie sie uns intuitiv erscheint und gewisser Möglichkeiten, die der Idee der Erfahrung implizit innewohnen: der Möglichkeiten von Illusion und Halluzination. Die perzeptuelle Erfahrung kommt uns vor wie eine Einstellung zu den eigenen Objekten, eine Art „Weltoffenheit“, die ein direktes Bewusstsein von den bestehenden Objekten und ihren Eigenschaften einschließt. Doch wenn jemand eine gleichartige Erfahrung haben kann, ohne dass das Objekt da wäre – Halluzination dieses Objektes – dann scheint die perzeptuelle Erfahrung unmöglich essenziell ein solches Verhältnis zu sein. Dies ist das fundamentale philosophische Problem der Perzeption; verschiedene philosophische Perzeptionstheorien des 20. und 21. Jahrhunderts können als Antworten darauf verstanden werden
