This brief, affordable text helps students to think critically, using examples from the weird claims and beliefs that abound in our culture to demonstrate the sound evaluation of any claim. It explains step-by-step how to sort through reasons, evaluate evidence, and tell when a claim is likely to be true. The emphasis is neither on debunking nor on advocating specific assertions, but on explaining principles of critical thinking that enable readers to evaluate claims for themselves. The authors focus on types (...) of logical arguments and proofs, making How to Think about Weird Things a versatile supplement for logic, critical thinking, philosophy of science, or any other science appreciation courses.

Some believe that evidence for the big bang is evidence for the existence of god. Who else, they ask, could have caused such a thing? In this paper, I evaluate the big bang argument, compare it with the traditional first-cause argument, and consider the relative plausibility of various natural explanations of the big bang.

Ted Schick submits the ‘God hypothesis’ to close scientific and logical scrutiny and finds it seriously lacking.

Ted Schick grapples with the New Age thinker Fritjof Capra. Is Capra right to suggest that the Eastern Mystics have been vindicated by the discoveries of modern science?

The correspondence theory of truth has often been attacked on the grounds that the notion of correspondence is too vague to do any serious philosophical work. More recently it has been attacked on the grounds that the sort of correspondence required by the theory does not exist.I argue, on the contrary, that there are no compelling reasons for believing that the requisite sort of correspondence does not exist and that the notion of correspondence can be made clear enough to yield (...) an adequate theory of truth. After critically examining Tarkski’s theory of truth, Ishow how a correspondence theory which applies to the statements of any language can be constructed. Then Davidson’s claim that all true statements correspond to the same thing and Putnam’s claim that there is no fact of the matter concerning what the terms of a language correspond to are shown to be untenable.

We show that the Π 0 2 enumeration degrees are not dense. This answers a question posed by Cooper.

Like the cracking of the genetic code and the creation of the atomic bomb, the discovery of how the brain's neurons work is one of the fundamental scientific developments of the twentieth century. The discovery of neurotransmitters revolutionized the way we think about the brain and what it means to be human yet few people know how they were discovered, the scientists involved, or the fierce controversy about whether they even existed. The War of the Soups and the Sparks tells (...) the saga of the dispute between the pharmacologists, who had uncovered the first evidence that nerves communicate by releasing chemicals, and the neurophysiologists, experts on the nervous system, who dismissed the evidence and remained committed to electrical explanations. The protagonists of this story are Otto Loewi and Henry Dale, who received Nobel Prizes for their work, and Walter Cannon, who would have shared the prize with them if he had not been persuaded to adopt a controversial theory (how that happened is an important part of this history). Valenstein sets his story of scientific discovery against the backdrop of two world wars and examines the fascinating lives of several scientists whose work was affected by the social and political events of their time. He recounts such stories as Loewi's arrest by Nazi storm troopers and Dale's efforts at helping key scientists escape Germany. The War of the Soups and the Sparks reveals how science and scientists work. Valenstein describes the observations and experiments that led to the discovery of neurotransmitters and sheds light on what determines whether a novel concept will gain acceptance among the scientific community. His work also explains the immense importance of Loewi, Dale, and Cannon's achievements in our understanding of the human brain and the way mental illnesses are conceptualized and treated. (shrink)

Based on lectures delivered at the Collège de France in May 1986.

These essays explore the continuities and discontinuities between the Neo-Confucian thought of Ming China and early Tokugawa Japan and the "practical learning" of the 17th and 18th centuries, underlining the need for a deeper examination of the complex relationship between "traditional" and "modern" thoughts and values.

Most theories of learning consider inferring a function f from either observations about f or, questions about f. We consider a scenario whereby the learner observes f and asks queries to some set A. If I is a notion of learning then I[A] is the set of concept classes I-learnable by an inductive inference machine with oracle A. A and B are I-equivalent if I[A] = I[B]. The equivalence classes induced are the degrees of inferability. We prove several results about (...) when these degrees are trivial, and when the degrees are omniscient. (shrink)
