We present the intuitionistic version of PUC-Logic. After that, we present a constructive approach to Lewis’ counterfactual abstraction to show that it does not require the classical absurd rule.

Timothy Williamson, in various places, has put forward an argument that is supposed to show that denying bivalence is absurd. This paper is an examination of the logical force of this argument, which

In our reply to Williamson, we offered models where traditional Gettier cases arise but which differ from Williamson’s models in three related respects: first, non-traditional, fake-barn style Gettier cases do not arise in our models; second, knowledge iterates in our models; and, finally, our models do not have the Moorish consequences of Williamson’s models.1 Predictably, Williamson thinks th...

Background The Royal College of Surgeons of England encouraged the creation of singly dedicated 24-hour emergency theatres in 1997; emergency operating was previously largely determined by theatre availability rather than clinical need. Shortly after this St George’s Hospital, London designated one of its three trauma theatres as an ‘Acute Emergency Theatre’ (AET) and implemented a policy to ma...

G. E. Moore famously observed that to say, I went to the pictures last Tuesday but I don’t believe that I did’’ would be ‘‘absurd’’. Why should it be absurd of me to say something about myself that might be true of me? Moore suggested an answer to this, but as I will show, one that fails. Wittgenstein was greatly impressed by Moore’s discovery of a class of absurd but possibly true assertions b...

This paper presents an interactive theatre based on an embodied mixed reality space and wearable computers. Embodied computing mixed reality spaces integrate ubiquitous computing, tangible interaction and social computing within a mixed reality space, which enables intuitive interaction with physical world and virtual world. We believe it has potential advantages to support novel interactive th...

BACKGROUND Retrograde ureteropyelography plays a vital role in imaging of the upper tract, particularly in aiding the diagnosis of upper tract urothelial cancers.1 Retrograde studies in theatre are often of inferior quality compared with those performed in the radiology department. Retrograde ureteric catheter placement in theatre is therefore followed by formal retrograde studies in the radiol...

In the context of the blurring of boundaries between club and theatre, game and theatre, and party and theatre, experiential spectatorship is spilling into the mainstream. This article starts from the recognition of the rapid rise of the experience economy as a turning point in consumer culture towards a specific appeal to the sensory body. The definition of experience in this analysis is key a...
