Life Is Strange and ‘‘Games Are Made’’: A Philosophical Interpretation of a Multiple-Choice Existential Simulator With Copilot Sartre

The multiple-choice video game Life is Strange was described by its French developers as a metaphor for the inner conflicts experienced by a teenager in trying to become an adult. In psychological work with adolescents, there is a stark similarity between what they experience and some concepts of existentialist philosophy. Sartre’s script for the movie Les Jeux Sont Faits (literally ‘‘games are made’’) uses the same narrative strategy as Life is Strange—the capacity for the main characters to travel back in time to change their own existence—in order to stimulate philosophical, ethical, and political thinking and also to effectively simulate existential ‘‘limit situations.’’ This article is a dialogue between Sartre’s views and Life is Strange in order to examine to what extent questions such as what is freedom? what is choice? what is autonomy and responsibility? can be interpreted anew in hybrid digital–human—‘‘anthrobotic’’—environments

On the Concept of Creal: The Politico-Ethical Horizon of a Creative Absolute

Process philosophies tend to emphasise the value of continuous creation as the core of their discourse. For Bergson, Whitehead, Deleuze, and others the real is ultimately a creative becoming. Critics have argued that there is an irreducible element of (almost religious) belief in this re-evaluation of immanent creation. While I don’t think belief is necessarily a sign of philosophical and existential weakness, in this paper I will examine the possibility for the concept of universal creation to be a political and ethical axiom, the result of a global social contract rather than of a new spirituality. I argue here that a coherent way to fight against potentially totalitarian absolutes is to replace them with a virtual absolute that cannot territorialise without deterritorialising at the same time: the Creal principle

Direct CP Violation in Charmless B Decays at LHCb

Using data collected by LHCb experiment in 2011 we report the measurements of charge asymmetries in charmless decays of B mesons in two or three charged kaons or pions. We find positive charge asymmetries in the channels Bs->K-pi+(3.3 sigmas), B+->K+pi+pi- (2.8 sigmas), and B+->pi+pi+pi- (4.2 sigmas) and negative in B0->K+pi-(6 sigmas),B+->K+K+K- (3.7 sigma), B+->K+K-pi+ (3.0 sigma).Comment: Proceedings of CKM 2012, the 7th International Workshop on the CKM Unitarity Triangle, University of Cincinnati, USA, 28 September - 2 October 201

Marginal extension in the theory of coherent lower previsions

AbstractWe generalise Walley’s Marginal Extension Theorem to the case of any finite number of conditional lower previsions. Unlike the procedure of natural extension, our marginal extension always provides the smallest (most conservative) coherent extensions. We show that they can also be calculated as lower envelopes of marginal extensions of conditional linear (precise) previsions. Finally, we use our version of the theorem to study the so-called forward irrelevant product and forward irrelevant natural extension of a number of marginal lower previsions

Independent natural extension for sets of desirable gambles

We investigate how to combine a number of marginal coherent sets of desirable gambles into a joint set using the properties of epistemic irrelevance and independence. We provide formulas for the smallest such joint, called their independent natural extension, and study its main properties. The independent natural extension of maximal sets of gambles allows us to define the strong product of sets of desirable gambles. Finally, we explore an easy way to generalise these results to also apply for the conditional versions of epistemic irrelevance and independence

Finitely additive extensions of distribution functions and moment sequences: The coherent lower prevision approach

We study the information that a distribution function provides about the finitely additive probability measure inducing it. We show that in general there is an infinite number of finitely additive probabilities associated with the same distribution function. Secondly, we investigate the relationship between a distribution function and its given sequence of moments. We provide formulae for the sets of distribution functions, and finitely additive probabilities, associated with some moment sequence, and determine under which conditions the moments determine the distribution function uniquely. We show that all these problems can be addressed efficiently using the theory of coherent lower previsions
