Gordon Baker and I had been colleagues at St John’s for almost ten years when we resolved, in 1976, to undertake the task of writing a commentary on Wittgenstein’s Philosophical Investigations. We had been talking about Wittgenstein since 1969, and when we cooperated in writing a long critical notice on the Philosophical Grammar in 1975, we found that working together was mutually instructive, intellectually stimulating and great fun. We thought that we still had much to say about Wittgenstein’s philosophy, and (...) it seemed to us that misinterpretations of passages in the Investigations were so extensive that it would be worth trying to write a detailed analytical commentary. It is difficult to recapture the excitement of those early days in being among the first to work on the microfilms and, subsequently, on the photocopies of Wittgenstein’s Nachlass. We spent many hundreds of hours poring over the typescripts and the often only semi-legible manuscripts, fascinated and privileged to be able to try to follow the development of the thoughts of a great philosophical genius. We talked endlessly about what we had found in Wittgenstein’s manuscripts and typescripts, and debated how it should be understood. The first fruit of our labours was Wittgenstein – Understanding and Meaning. Its guiding idea was to draw attention to the manner in which Wittgenstein linked the concepts of meaning, understanding and explanation, and so to bypass the connections between meaning, truth and truth-conditions that so fascinated philosophers of the 1970s, and to abandon the red-herring of assertion-conditions and anti-realism. After a hiatus of four years, during which time we wrote a controversial book entitled Frege – Logical Excavations and a polemical book on contemporary philosophy of language – Language, Sense.

Engineering is 'the people-serving profession'. The work of engineers involves interaction with clients, other engineers, and the public at large. More than any other profession, their work also directly involves and affects the environment. This book makes the case that engineers have special professional obligations to protect and enhance the environment, and the authors - one, an engineer and the other, a philosopher - seek to provide an ethical basis for these obligations. In exploring these ethical issues, the authors aim (...) to show that engineers make a difference. The text opens with a series of case studies in which engineers face complex and challenging decisions about the environment. Succeeding chapters examine different ideas about environmental ethics for engineers, including professional codes and both modern and historical discussions of environmental responsibility. The book concludes with a collection of readings that complement the text. Students, as well as practising engineers, will find much of interest in this well-argued and thought-provoking book.

This article explores three ways in which a cognitively entrenched mindreading (or 'theory of mind') system may bias our thinking as cognitive scientists. One issues in a form of tacit dualism, impacting scientific debates about phenomenal consciousness. Another leads us to think that our own minds are easier to know than they really are, influencing debates about self-knowledge, and about mindreading itself. And the third results in a bias in favour of empiricist over nativist accounts of cognitive development. The discussion (...) throughout is tentative and speculative, and can be regarded as an appeal for caution, as well as a call for further research. (shrink)

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

In what sense can the sciences be said to constitute a (set of) specific cultural tradition(s) within broader culture? This is the proper way of posing the problem of the 'two cultures' today. For G. Bachelard the opposition between 'poem' and 'theorem' was fundamental, the elements of poetical imagination being radically different from the symbolical constructions of conceptual invention. In this article a sophisticated version of this point of view is proposed. The nowadays popular attempts to bridge all gaps between (...) the cultures by an appeal to creative imagination ('science as art', 'mathematics and poetry') are criticized. The real basis of considering research traditions nevertheless as cultural realities in a nontrivial sense is not to be found in a mediation between cognitive faculties, but has to be revealed by a comparative analysis of their respective products. In fact, science, as well as other cultural practices, is subject to variations of style (Granger, Hacking ...). Research styles are not in the first place due to external, sociological determinants, but to such factors as the necessity of individuating any idea in a work, the presence of changing images of science within each discipline, and the fundamental role of the not-yet-explicit, given the specific temporal structure of conceptual innovation with its „essential tension” (Kuhn) between the old and the new.
