This text analyses a variety of thought experiments, and explores what they are, how they work, and what their positive and negative aspects are. It also sets the theory within an evolutionary framework of advances in experimental psychology.
About the fifth century BC, three civilizations independently and simultaneously began to philosophize about nothing: China (chapter 3), India (chapters 4 and 5), and Greece (chapters 6-10). They had previously focused on what is the case. Light poured on nature, architecture, and society. But then, in a cross-civilizational black-out, emerged disparate nay-sayers who shifted attention to what is not the case. Behold, the holes in a sponge are absences of sponge! Holes are what make the sponge useful for absorbing liquid. The sponge can exist without the holes. But the holes cannot "exist" without the sponge. They are parasites that depend on their host. Yet the two get along well. Without holes, there would not be so many sponges in your house. Your shadow is a more complex parasite. It is a hole you bore into the light. Your shadow depends on both you and the light. You and light are rather mysterious. Your shadow partakes of both mysteries. .
Roy Sorensen here defends the causal theory of perception by treating absences as causes. He draws heavily on common sense and psychology to vindicate the assumption that we directly perceive absences.
Can God create a stone too heavy for him to lift? Can time have a beginning? Which came first, the chicken or the egg? Riddles, paradoxes, conundrums--for millennia the human mind has found such knotty logical problems both perplexing and irresistible. Now Roy Sorensen offers the first narrative history of paradoxes, a fascinating and eye-opening account that extends from the ancient Greeks, through the Middle Ages, the Enlightenment, and into the twentieth century. When Augustine asked what God was doing before He made the world, he was told: "Preparing hell for people who ask questions like that." A Brief History of the Paradox takes a close look at "questions like that" and the philosophe...
In 1942 G.E. Moore first wrote about the curious sort of "nonsense" exhibited by the statement "it is raining but I do not believe it". What Moore discovered was a species of blindspots: consistent propositions that cannot be rationally accepted by certain individuals even though they mightbe true. In this book, Professor Sorenson aims to provide a unified solution to a large family of philosophical puzzles and paradoxes through a study of blindspots. He devotes special attention to revealing their role in "slippery slope" reasoning.
A Cabinet of Philosophical Curiosities is a collection of puzzles, paradoxes, riddles, and miscellaneous logic problems. Depending on taste, one can partake of a puzzle, a poem, a proof, or a pun.
First published in 1993. Why do mirrors reverse left and right but not up and down? Does time flow at an even rate? These are just two of the questions that won't be answered in Pseudo-Problems. This book explains how problems are dissolved rather than solved. Roy Sorenson takes the most important and interesting examples from one hundred years of analytic philosophy (and the odd one from the centuries before) to consolidate a new theory of dissolution. Pseudo-Problems is a fast-moving, fascinating alternative history of twentieth-century analytic philosophy, and a fine example of what philosophical analysis should be. Not least, it is an important contribution to the debates about creativity and problem solving.

Did Buddha become a fat man in one second? Is there a tallest short giraffe? Epistemicists answer 'Yes!' They believe that any predicate that divides things divides them sharply. They solve the ancient sorites paradox by picturing vagueness as a kind of ignorance. The alternative solutions are radical. They either reject classical theorems or inference rules or reject our common sense view of what can exist. Epistemicists spare this central portion of our web of belief by challenging peripheral intuitions about the nature of language. So why is this continuation of the status quo so incredible? Why do epistemicists themselves have trouble believing their theory? In Vagueness and Contradictio...
Sorensen presents a general theory of thought experiments: what they are, how they work, what are their virtues and vices. On Sorensen's view, philosophy differs from science in degree, but not in kind. For this reason, he claims, it is possible to understand philosophical thought experiments by concentrating on their resemblance to scientific relatives. Lessons learned about scientific experimentation carry over to thought experiment, and vice versa. Sorensen also assesses the hazards and pseudo-hazards of thought experiments. Although he grants that there are interesting ways in which the method leads us astray, he attacks most scepticism about thought experiments as arbitrary. They should be used, he says, as they generally are used--as part of a diversified portfolio of techniques. All of these devices are individually susceptible to abuse, fallacy, and error. Collectively, however, they provide a network of cross-checks that make for impressive reliability.
