It is a study of the phenomenological philosophies of Husserl and Heidegger. Through a critical discussion including practically all previously published English and German literature on the subject, the aim is to present a thorough and evenhanded account of the relation between the two. The book provides a detailed presentation of their respective projects and methods, and examines several of their key phenomenological analyses, centering on the phenomenon of being-in-the-world. It offers new perspectives on Husserlian and Heideggerian phenomenology, e.g. concerning the importance of Husserl's phenomenology of the body, the relationship between the Husserlian concept of "constitution" and Heidegger's notion of "transcendence", as well as in its argument that "being" designates the central phenomenon for both phenomenologists. Though the study sacrifices nothing in terms of argumentative rigor or interpretative detail, it is written in such a way as to be accessible and rewarding to non-specialists and specialists alike

AbstractNumerous philosophers accept the differentiation condition, according to which one does not see an object unless one visually differentiates it from its immediate surroundings. This paper, however, sounds a sceptical note. Based on suggestions by Dretske (2007) and Gibson (2002 [1972]), I articulate two 'principles of occlusion' and argue that each principle admits of a reading on which it is both plausible and incompatible with the differentiation condition. To resolve the inconsistency, I suggest we abandon the differentiation condition.

Phenomenology was one of the twentieth century's major philosophical movements and continues to be a vibrant and widely studied subject today. The Routledge Companion to Phenomenology is an outstanding guide and reference source to the key philosophers, topics and themes in this exciting subject, and essential reading for any student or scholar of phenomenology. Comprising over fifty chapters by a team of international contributors, the Companion is divided into five clear parts: • main figures in the phenomenological movement, from Brentano to Derrida • main topics in phenomenology • phenomenological contributions to philosophy • phenomenological intersections • historical postscript. Close attention is paid to the core topics in phenomenology such as intentionality, perception, subjectivity, the self, the body, being and phenomenological method. An important feature of the Companion is its examination of how phenomenology has contributed to central disciplines in philosophy such as metaphysics, philosophy of mind, moral philosophy, aesthetics and philosophy of religion as well as disciplines beyond philosophy such as race, cognitive science, psychiatry, literary criticism and psychoanalysis.

» When introducing an implant, surgeons are subjected to steep learning curves, which may lead to a heightened revision rate. Stepwise introduction revolutionized implant introduction but lacks a last step. » No guidelines exist for the introduction of a well-documented implant not previously used in a department. This is problematic according to the European Union's legislated tendering process, potentially leading to increased revisions. In this systematic review, the introduction of a well-documented total hip arthroplasty implant to experienced surgeons is explored amid concerns of higher revision rate. » Literature search strategies were deployed in the Embase and Medline databases, revealing a total of 14,612 articles. Using the Covidence software (Cochrane, London), two reviewers screened articles for inclusion. » No articles were found that fulfilled our eligibility criteria. A post hoc analysis retrieved two national register-based studies only missing information about the surgeon's knowledge of the introduced implant. None of the introduced implants decreased the revision rate and around 30% of the introduced implants were associated with a higher revision rate. » The review showed that no data exist about revision rates when introducing well-documented implants. In continuation thereof, the introduction of well-documented implants might also be associated with increased revision rates, as has been shown for total knee arthroplasty. We therefore suggest that special attention should be focused on changes of implants in departments, which can be achieved by way of specific registration in national registers.
