The question of who has the burden of proof is often important in practice. We must frequently make decisions and act on the basis not of conclusive evidence but of what is reasonable to presume true. Consequently, it happens that a given practical question must be solved by referring to principles that explicitly or implicitly determine, at least partly, where the burden of proof should rest. In this essay, I consider the role of the logic of the burden of proof (...) in a debate on global justice. In particular, I ask how the logic of the burden of proof is seen by those who defend conservative positions in a debate and deny our obligations to reduce poverty beyond borders. I argue that defenders of conservative positions tend to shift the burden of proof in an unjustified way. (shrink)

Smart Thinking: Skills for Critical Understanding and Writing 2E is a practical step-by-step guide to improving skills in analysis, critical thinking, and the effective communication of arguments and explanations. The book combines an accessible and straightforward style, with a strong foundation of knowledge. The text treats reasoning as an aspect of communication, not an abstract exercise in logic. The book not only provides detailed advice on how to practise analytical skills, but also demonstrates how these skills can be used in (...) research and writing. In particular, it emphasises how to develop arguments that are coherent and that take account of their audience and context. (shrink)

If a tree falls in the forest and no one is present to hear it, does it make a sound? It does not, according to George Berkeley. Originally published in 1710, this landmark of Western philosophy introduced a revolutionary concept: immaterialism, which asserts that to be is to perceive or be perceived. The treatise opens with an assault on Locke's theory of abstract ideas and proceeds with arguments that sensible qualities exist only when perceived as ideas. Physical objects, he claims, (...) are no more than collections of qualities, and these sensible objects, too, are merely ideas. Berkeley relates his position to the achievements of eighteenth-century science, and proclaims the compatibility of immaterialism with traditional religion. (shrink)

The examination of the notion of science from a sociological perspective has begun to transform the attitudes to science traditionally upheld by historians and philosophers.
