Here the philosopher and physicist David Z Albert argues, among other things, that the difference between past and future can be understood as a mechanical phenomenon of nature and that quantum mechanics makes it impossible to present the entirety of what can be said about the world as a narrative of “befores” and “afters.”.

In the recent literature on concepts, two extreme positions concerning animal minds are predominant: the one that animals possess neither concepts nor beliefs, and the one that some animals possess concepts as well as beliefs. A characteristic feature of this controversy is the lack of consensus on the criteria for possessing a concept or having a belief. Addressing this deficit, we propose a new theory of concepts which takes recent case studies of complex animal behavior into account. The main aim (...) of the paper is to present an epistemic theory of concepts and to defend a detailed theory of criteria for having concepts. The distinction between nonconceptual, conceptual, and propositional representations is inherent to this theory. Accordingly, it can be reasonably argued that some animals, e.g., grey parrots and apes, operate on conceptual representations. (shrink)

E. J. Lowe offers an account of modal knowledge that involves two primary theses. First, the basis of modal knowledge is essential knowledge, and the source of essential knowledge is grasp of essence. Second, all empirical knowledge ultimately depends on some modal knowledge. This article assesses Lowe’s account and defends four conclusions. First, there is a tension in Lowe’s account of grasp of essence; it wavers between an undemanding version, which holds that grasp of essence requires no more than our (...) ordinary understanding of propositions, and a more demanding version, which holds that it requires rational insight into necessary relationships between essences. Second, both versions face serious challenges. Third, Lowe’s account of knowledge of essence does not provide a basis for modal knowledge. Fourth, Lowe’s supporting argument for his second thesis contains two significant gaps and the principles necessary to close the gaps reveal further tensions in his epistemological views. (shrink)

Engineering the Climate: The Ethics of Solar Radiation Management is a wide-ranging and expert analysis of the ethics of the intentional management of solar radiation. This book will be a useful tool for policy-makers, a provocation for ethicists, and an eye-opening analysis for both the scientist and the general reader with interest in climate change.

The scientific investigation of consciousness generates new findings at a rapid pace. We argue that we need a novel theoretical framework, which we call the ALARM theory of consciousness, in order to account for all central observations. According to this theory, we need to distinguish two levels of consciousness, namely basic arousal and general alertness. Basic arousal functions as a specific alarm system, keeping a biological organism alive under sudden intense threats, and general alertness enables flexible learning and behavioural strategies. (...) This two-level theory of consciousness helps us to account for (i) recent discoveries of subcortical brain activities with a central role of thalamic processes, (ii) observations of differences in the behavioural repertoire of non-human animals indicating two types of conscious experiences. Furthermore, the framework enables us (iii) to unify the neural evidence for the relevance of subcortical processes, on the one hand, and of cortico-cortical loops, on the other, and finally (iv) to clarify the evolutionary and actual functional role of conscious experiences.

We argue that thinking of the man-machine comparison in terms of a contest involves, in a reasonable scenario, a criterion of success that is neutral. This is because we want to avoid a petitio principii. We submit, however, that, by looking at things this way, one makes the most essential human things invisible. Thus, in a sense, the contest approach is self-defeating.

Bioethics Beyond the Headlines is a primer in bioethics. You will not find convoluted philosophical arguments in this volume. Rather, you will find an engaging sampling of the key questions in bioethics, including euthanasia, assisted reproduction, cloning and stem cells, neuroscience, access to healthcare, and even research on animals and questions of environmental ethics—areas typically overlooked in general introductions to bioethics.

: Leibniz was writing his Discourse on the Natural Theology of the Chinese as the Leibniz-Clarke Controversy developed. Both were terminated by his death. These two fronts show interesting doctrinal correlations. The first is Leibniz' concern for the ''decadence of natural religion.'' The dispute with Clarke began with it, and the Discourse is a defense of Chinese natural religion in order to show its agreement with Christian natural religion. The Controversy can be summed up as ''clockmaker God versus idle God.'' (...) Leibniz wants to escape from the perverse consequences that all criticism of divine voluntarism seems to cause. Thus, his elaboration is directed at a distinct concept of a God that rules without interposing, a supramundane intelligence. And the Leibnizian interpretation of the natural theology of the Chinese can be viewed the same way: it emphasizes a First Principle, Li, which rules without interposing. (shrink)

This is an English translation of one of the more challenging and enigmatic of Plato's dialogues between Socrates and Parmenides and Zeno of Elea, that begins with Zeno defending his treatise of Parmenidean monism against those partisans of plurality. Focus Philosophical Library translations are close to and are non-interpretative of the original text, with the notes and a glossary intending to provide the reader with some sense of the terms and the concepts as they were understood by Plato’s immediate audience.
