In “The Location Problem for Color Subjectivism,” Peter Ross argues against what he calls subjectivism — the view that “colors are not describable in physical terms, ... [but are] mental processes or events of visual states” (2),¹ and in favor of physicalism — a view according to which colors are “physical properties of physical objects, such as reflectance properties” (10). He rejects an argument that has been offered in support of subjectivism, and argues that, since no form of subjectivism is able to account for our perception of color, we are better off adopting physicalism.

The traditional disputants in the free will discussion--the libertarian, soft determinist, and hard determinist--agree that free will is a coherent concept, while disagreeing on how the concept might be satisfied and whether it can, in fact, be satisfied. In this innovative analysis, Richard Double offers a bold new argument, rejecting all of the traditional theories and proposing that the concept of free will cannot be satisfied, no matter what the nature of reality. Arguing that there is unavoidable conflict within our understanding of moral responsibility and free choice, Double seeks to prove that when we ascribe responsibility, blame, or freedom, we merely express attitudes, rather than state anything capable of truth or falsity. Free will, he concludes, is essentially an incoherent notion.

In The Ethical Primate, renowned philosopher Mary Midgley tackles important questions about human freedom and morality. Scientists and philosophers have found it difficult to understand how each human being can be both a living part of the natural world and, at the same time, a genuinely free agent. Midgley explores their responses to this seeming paradox and argues that our evolutionary origin, properly understood, explains why human freedom and morality have come about.

According to color subjectivism, colors are mental properties, processes, or events of visual experiences of color. I first lay out an argument for subjectivism founded on claims from visual science and show that it also relies on a philosophical assumption. I then argue that subjectivism is untenable because this view cannot provide a plausible account of color perception. I describe three versions of subjectivism, each of which combines subjectivism with a theory of perception, namely sense datum theory, adverbialism, and the virtual color proposal, and argue that each version faces serious objections. Considering these three theories of perception to be exhaustive of those available to the subjectivist, I conclude that subjectivism is untenable and that the scientifically motivated argument for this view is unsound. I then offer the diagnosis that the philosophical assumption on which this argument relies is mistaken.

Meta-ethical discussions commonly distinguish 'subjectivism' from 'emotivism', or 'expressivism'. But Frank Jackson and Philip Pettit have argued that plausible assumptions in the philosophy of language entail that expressivism collapses into subjectivism. Though there have been responses to their argument, I think the responses have not adequately diagnosed the real weakness in it. I suggest my own diagnosis, and defend expressivism as a viable theory distinct from subjectivism.

Epistemic subjectivism, as I am using the term, is a view in the same spirit as relativism, rooted in skepticism about the objectivity or universality of epistemic norms. I explore some ways that we might motivate subjectivism drawing from some common themes in analytic epistemology. Without diagnosing where the arguments go wrong, I argue that the resulting position is untenable.

Much has been written recently about free will and moral responsibility. In this paper I will focus on the relationship between free will, on the one hand, and various notions that fall under the rubric of “morality,” broadly construed, on the other: deliberation and practical reasoning, moral responsibility, and ethical notions such as “ought,” “right,” “wrong,” “good,” and “bad.” I shall begin by laying out a natural understanding of freedom of the will. Next I develop some challenges to the common-sense view that we have this sort of freedom. I will go on to explore the implications of this challenge for deliberation, moral responsibility, and the central ethical notions.

On the whole, we continue to believe firmly both that we have free will and that we are morally responsible for what we do. Here, the author argues that there is a fundamental sense in which there is no such thing as free will or true moral responsibility (as ordinarily understood). Devoting the main body of his book to an attempt to explain why we continue to believe as we do, Strawson examines various aspects of the "cognitive phenomenology" of freedom--the nature, causes, and consequences of our deep commitment to belief in freedom.

Why is debate over the free will problem so intractable? In this broad and stimulating look at the philosophical enterprise, Richard Double uses the free will controversy to build on the subjectivist conclusion he developed in The Non-Reality of Free Will (OUP 1991). Double argues that various views about free will--e.g., compatibilism, incompatibilism, and even subjectivism--are compelling if, and only if, we adopt supporting metaphilosophical views. Because metaphilosophical considerations are not provable, we cannot show any free will theory to be most reasonable. Metaphilosophy and Free Will deconstructs the free will problem and, by example, challenges philosophers in other areas to show how their philosophical argumentation can succeed.
