Abstract: We regularly wield powers that, upon close scrutiny, appear remarkably magical. By sheer exercise of will, we bring into existence things that have never existed before. With but a nod, we effect the disappearance of things that have long served as barriers to the actions of others. And, by mere resolve, we generate things that pose significant obstacles to others’ exercise of liberty. What is the nature of these things that we create and destroy by our mere decision to do so? The answer: the rights and obligations of others. And by what seemingly magical means do we alter these rights and obligations? By making promises and issuing or revoking consent When we make promises, we generate obligations for ourselves, and when we give consent, we create rights for others. Since the rights and obligations that are affected by means of promising and consenting largely define the boundaries of permissible action, our exercise of these seemingly magical powers can significantly affect the lives and liberties of others
Obligation and Consent – I
Introduction: One might suppose that if political theorists are by now clear about anything at all, they should be clear about the problem of political obligation and the solution to it most commonly offered, the doctrine of consent. The greatest modern political theorists took up this problem and formulated this answer. The resulting theories are deeply imbedded in our American political tradition; as a consequence we are al- ready taught a sort of rudimentary consent theory in high school. And yet I want to suggest that we are not even now clear on what “the problem of political obligation” is, what sorts of “answers” are appropriate to it, what the con- sent answer really says, or whether it is a satis- factory answer. This essay is designed to point up the extent of our confusion, to explore some of the ground anew as best it can, and to invite further effort by others. That such effort is worthwhile, that such political theory is still worth considering and that it can be made genuinely relevant to our world, are the assump- tions on which this essay rests and the larger message it is meant to convey
Theories of Vagueness
Publisher’s Note: Most expressions in natural language are vague. But what is the best semantic treatment of terms like ‘heap’, ‘red’ and ‘child’? And what is the logic of arguments involving this kind of vague expression? These questions are receiving increasing philosophical attention, and in this timely book Rosanna Keefe explores the questions of what we should want from an account of vagueness and how we should assess rival theories. Her discussion ranges widely and comprehensively over the main theories of vagueness and their supporting arguments, and she offers a powerful and original defence of a form of supervaluationism, a theory that requires almost no deviation from standard logic yet can accommodate the lack of sharp boundaries to vague predicates and deal with the paradoxes of vagueness in a methodologically satisfying way. Her study will be of particular interest to readers in philosophy of language and of mind, philosophical logic, epistemology and metaphysics.
Symmetry and Symmetry Breaking
Introduction: Symmetry considerations dominate modern fundamental physics, both in quantum theory and in relativity. Philosophers are now beginning to devote increasing attention to such issues as the significance of gauge symmetry, quantum particle identity in the light of permutation symmetry, how to make sense of parity violation, the role of symmetry breaking, the empirical status of symmetry principles, and so forth. These issues relate directly to traditional problems in the philosophy of science, including the status of the laws of nature, the relationships between mathematics, physical theory, and the world, and the extent to which mathematics suggests new physics.
This entry begins with a brief description of the historical roots and emergence of the concept of symmetry that is at work in modern science. It then turns to the application of this concept to physics, distinguishing between two different uses of symmetry: symmetry principles versus symmetry arguments. It mentions the different varieties of physical symmetries, outlining the ways in which they were introduced into physics. Then, stepping back from the details of the various symmetries, it makes some remarks of a general nature concerning the status and significance of symmetries in physics.
Understanding and The Facts
Abstract: If understanding is factive, the propositions that express an understanding are true. I argue that a factive conception of understanding is unduly restrictive. It neither reflects our practices in ascribing understanding nor does justice to contemporary science. For science uses idealizations and models that do not to mirror the facts. Strictly speaking, they are false. By appeal to exemplification, I devise a more generous, flexible conception of understanding that accommodates science, reflects our practices, and shows a sufficient but not slavish sensitivity to the facts.
White Ignorance
The development of social epistemology in recent decades is a welcome turn away from Cartesian individualism. But the centrality of oppression to societies in general is still insufficiently recognized in this literature. This chapter looks at white ignorance as an example of a particular kind of systemic group-based miscognition that has been hugely influential over the past few hundred years. After a ten-point clarification of the concept, it turns to an examination of white ignorance as it plays itself out in the complex interaction of Eurocentric perception and categorization, white normativity, social memory and social amnesia, the derogation of non-white testimony, racial group interests, and motivated irrationality.
Musing: A Black Feminist Philosopher: Is that Possible?
Summary: The author argues that black feminist philosophy exists, but “it exists elsewhere in other spaces, on the pages of journals that professional philosophers do not read, in the contexts of conferences where professional philosophers do not go”.
Do our modern skulls house stone-age minds?
Summary: This is the fifth chapter of the book Philosophy and the Sciences for Everyone. The chapter explores scientific interpretations of how our minds evolved, and some of the methodologies used in forming these interpretations. It relates evolutionary debates to a core issue in the philosophy of mind, namely, whether all knowledge comes from experience, or whether we have ‘inborn’ knowledge about certain aspects of our world.
What is this thing called science?
Summary: This chapter offers a general introduction to philosophy of science. The first part of the chapter takes the reader through the famous relativist debate about Galileo and Cardinal Bellarmine. Several important questions on the topic are explored, such as what makes scientific knowledge special compared with other kinds of knowledge or the importance of demarcating science from non-science. Finally, the chapters gives an overview on how philosophers such as Popper, Duhem, Quine and Kuhn came to answer these questions.
From Intelligent machines to the human brain
Summary: How does one make a clever adaptive machine that can recognise speech, control an aircraft, and detect credit card fraud? Recent years have seen a revolution in the kinds of tasks computers can do. Underlying these advances is the burgeoning field of machine learning and computational neuroscience. The same methods that allow us to make clever machines also appear to hold the key to understanding ourselves: to explaining how our brain and mind work. This chapter explores this exciting new field and some of the philosophical questions that it raises.
