Among the very many puzzling aspects of the physical world is this: how do we explain the fact that the laws of thermodynamics are time-asymmetric while those of statistical mechanics are time-symmetric? If the fundamental physical laws do not require events to occur in any particular temporal direction, why do we observe a world in which, for example, we will always see milk dispersing in tea but never coming together in tea – at least not unless we film the dispersal and then run the film backwards? In The Road to Maxwell’s Demon: Conceptual Foundations of Statistical Mechanics (Cambridge University Press, 2012), Meir Hemmo of the University of Haifa and Orly Shenker of the Hebrew University of Jerusalem provide a fascinating and accessible defense of the position that the laws of thermodynamics are observer-relative, that the evolutions of physical microstates in classical mechanics have a direction of time but no determinate direction, and that the relation between observers and the dynamics determines the direction of time that we observe and capture in our thermodynamical laws. In consequence, they argue, it’s just a contingent fact that we remember the past rather than the future, and Maxwellian Demons – perpetual motion machines that can exploit more and more energy while putting in less and less work – are possible.

Pragmatism is American’s home-grown philosophy, but it is not widely understood. This partly is due to the fact that pragmatism emerged out of deep philosophical disputes among its earliest proponents: Charles Sanders Peirce, William James, and John Dewey. Although it is agreed that they are the founders of Pragmatism, they also held opposing views about meaning, truth, reality, and value. A further complication emerges in that it is widely believed that Pragmatism was purged from the philosophical mainstream and rendered dormant sometime around 1950, and then recovered only in the 1980s by Richard Rorty.

For decades now, philosophers, linguists, psychologists and neuroscientists have been working to understand the nature of the hard-to-describe but very familiar conscious experiences we have while awake. Some have thought consciousness can’t be explained scientifically, and others have argued that it will always remain a mystery. But most consider some sort of explanation in physical, specifically neural, terms to be possible. In The Conscious Brain: How Attention Engenders Experience (Oxford University Press, 2012), Jesse J. Prinz — Distinguished Professor of Philosophy at the City University of New York Graduate Center — synthesizes scientific data and hypothesis with philosophical theory and insight to argue for the AIR theory of consciousness. On his view, consciousness is Attention to Intermediate-level Representations, attention is availability to working memory, and availability to working memory is realized by synchronized neural activity in the gamma frequency range. In this deftly written book, Prinz also provides novel arguments against competitor theories, argues against the idea that there is a phenomenal self, and proposes a mind-body metaphysics that draws on insights from both non-reductive and reductive physicalism.

Contemporary philosophers still wrestle mightily with Plato’s Republic. A common reading has it that in the Republic, Plato’s character Socrates defends a conception of justice according to which reason should rule the soul and philosophers should rule the city. On all accounts, the Republic is centrally concerned with the question of what philosophers are and how they come to be. A standard reading contends that the multiple discussions in the Republic of the nature of the philosopher all aim to depict the very same kind of creature.

Many philosophers have written on the ways in which human beings produce artifacts and on the nature of artifacts themselves, often distinguishing the act of producing or making from growing, and distinguishing artifacts from natural objects. However, such discussions have tended to be theoretically restrictive – for example, in philosophy of technology, the focus is primarily on non-religious and non-artistic artifacts. In A Philosophy of Material Culture: Action, Function and Mind (Routledge 2012), Professor Beth Preston of the University of Georgia provides a foundation for understanding material culture in general – indeed, she uses the phrase “item of material culture” to avoid the restrictive connotations of “artifact”. Preston approaches her subject from two basic vantage points: the philosophy of action, to consider the nature of production and use of material culture, and the philosophy of function, to consider the nature of the items that are produced and used. In doing so she breaks new ground in understanding collaboration and improvisation, and draws on work on biological and system functions to develop a concept of ‘function’ appropriate to understanding the functions of the items we make and use.

There is a long-standing debate in epistemology between internalists and externalists about justification. Internalists think that a belief is justified in virtue of certain facts internal to the believer. Externalists deny this; they hold that facts of some other kind must obtain in order for a belief to be justified. In his new book, Justification and the Truth-Connection (Cambridge 2012), Clayton Littlejohn defends a novel version of externalism, one which holds that a belief must be true in order to be justified. The cover of the book features an intriguing photograph by Sigurdur Gudmundsson that nicely captures Littlejohn’s view: In order to meet our epistemic obligations, we must fit ourselves, including our internal belief-forming and deliberative processes as well as our actions, to the world around us. This view, Littlejohn contends, retains the virtues of justificatory externalism while also providing a compelling account of the concerns regarding epistemic normativity and responsibility that often lie at the core of internalist views of justification. Littlejohn’s book hence is a work of contemporary epistemology that engages deeply with a range of concerns in value theory.

It’s taken for granted among analytic philosophers that some of their primary areas of inquiry – ethics, epistemology, philosophy of mind and philosophy of language, in particular – involve a special and characteristic methodology that depends essentially on the use of intuitions as evidence for philosophical positions. A thought experiment is developed in order to elicit intuitive judgments, and these judgments have a special epistemic status. Paradigm cases of this methodology include Gettier cases, in which we judge whether the subject in the scenario has or does not have knowledge, and Putnam’s Twin-Earth cases, in which we judge whether the contents of thought depend on the physical nature of a thinker’s environment. The new experimental philosophy movement also accepts this assumption, as it is premised on rejecting it by conducting real experiments (with non-philosophers as subjects) rather than thought-experiments.

Religious conviction enjoys a privileged status in our society.This is perhaps most apparent in legal contexts, where religious conviction is often given special consideration. To be more precise, religious conscience is recognized as a legitimate basis for exemption from standing laws, whereas claims of conscience deriving from non-religious commitments generally are not. Why is this? Is there something special about religiously-based claims of conscience? Is there something special about religion such that it gives rise to claims of conscience that deserve special consideration? If so, what?

What do we experience we look at an object – say, a tomato? A traditional view holds that we entertain an internal picture or representation of the tomato, and moreover that this internal picture is of the surface of the tomato, and not, say, the side of the tomato that is hidden from view. This general view of experience has been criticized for some time by numerous scientists and philosophers, Alva Noe among them. In earlier books, Noe — professor of philosophy at the University of California at Berkeley — has defended the view that our experiences of the world are grounded in practical skills – our abilities to manipulate things, and their availability or accessibility to us. According to this enactive view of perception, the hidden side of the tomato is also in our conscious experience of it – it is, in Noe’s words, present as absent. In his new book, Varieties of Presence (Harvard University Press, 2012), Noe elaborates the enactive view further, to explain the nature of presence and of access: how the world shows up to us in experience, and how the way it shows up depends on our modes of access to it.

Liberal democracies are in the business of protecting individuals and their rights. Central among these are the rights to free expression, freedom of association, and freedom of conscience. Liberal democracies are also in the business of sustaining a political environment in which citizens are regarded as political equals. In exercising their rights, some citizens will come to hold beliefs and viewpoints that are fundamentally at odds with the idea that all citizens are their equals. That is, in a free society, some citizens will come to endorse views which reject the idea of a society of free and equal citizens. Such cases seem to put the liberal democratic state in a bind. It must permit citizens to adopt and express illiberal and anti-democratic viewpoints, or else violate its commitment to the core freedoms it prizes. Yet the spread of such viewpoints, and sometimes even their very expression, can threaten the equality other citizens and undermine the stability of a democratic society. What should the state do?
