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.

Available for the first time in 20 years, here are two important works from the 1920s by the best-known representative of the Vienna Circle. In The Logical Structure of the World, Carnap adopts the position of "methodological solipsism" and shows that it is possible to describe the world from the immediate data of experience. In his Pseudoproblems in Philosophy, he asserts that many philosophical problems are meaningless.

“A remarkable contribution to one of the most vexing problems in science: the ‘demarcation’ problem, or how to distinguish science from nonscience.” —Francisco J. Ayala, author of Darwin’s Gift to Science and Religion What sets the practice of rigorously tested, sound science apart from pseudoscience? In this volume, the contributors seek to answer this question, known to philosophers of science as “the demarcation problem.” This issue has a long history in philosophy, stretching as far back as the early twentieth century and the work of Karl Popper. But by the late 1980s, scholars in the field began to treat the demarcation problem as impossible to solve and futile to ponder. However, the essays that Massimo Pigliucci and Maarten Boudry have assembled in this volume make a rousing case for the unequivocal importance of reflecting on the separation between pseudoscience and sound science. Moreover, the demarcation problem is not a purely theoretical dilemma of mere academic interest: it affects parents’ decisions to vaccinate children and governments’ willingness to adopt policies that prevent climate change. Pseudoscience often mimics science, using the superficial language and trappings of actual scientific research to seem more respectable. Even a well-informed public can be taken in by such questionable theories dressed up as science. Pseudoscientific beliefs compete with sound science on the health pages of newspapers for media coverage and in laboratories for research funding. Now more than ever the ability to separate genuine scientific findings from spurious ones is vital, and The Philosophy of Pseudoscience provides ground for philosophers, sociologists, historians, and laypeople to make decisions about what science is or isn’t. “A manual to overcome our natural cognitive biases.” —Corriere della Sera (Italy)

In a letter of 1932, Karl Popper described Die beiden Grundprobleme der Erkenntnistheorie – The Two Fundamental Problems of the Theory of Knowledge – as ‘...a child of crises, above all of ...the crisis of physics.’ Finally available in English, it is a major contribution to the philosophy of science, epistemology and twentieth century philosophy generally. The two fundamental problems of knowledge that lie at the centre of the book are the problem of induction, that although we are able to observe only a limited number of particular events, science nevertheless advances unrestricted universal statements; and the problem of demarcation, which asks for a separating line between empirical science and non-science. Popper seeks to solve these two basic problems with his celebrated theory of falsifiability, arguing that the inferences made in science are not inductive but deductive; science does not start with observations and proceed to generalise them but with problems, which it attacks with bold conjectures. The Two Fundamental Problems of the Theory of Knowledge is essential reading for anyone interested in Karl Popper, in the history and philosophy of science, and in the methods and theories of science itself.

Paul Horwich presents a bold new interpretation of Wittgenstein's later work. He argues that it is Wittgenstein's radically anti-theoretical metaphilosophy - and not his identification of the meaning of a word with its use - that underpins his discussions of specific issues concerning language, the mind, mathematics, knowledge, art, and religion.

This volume consists of papers inspired by the special session on pseudo-differential operators at the 10th ISAAC Congress held at the University of Macau, August 3-8, 2015 and the mini-symposium on pseudo-differential operators in industries and technologies at the 8th ICIAM held at the National Convention Center in Beijing, August 10-14, 2015. The twelve papers included present cutting-edge trends in pseudo-differential operators and applications from the perspectives of Lie groups (Chapters 1-2), geometry (Chapters 3-5) and applications (Chapters 6-12). Many contributions cover applications in probability, differential equations and time-frequency analysis. A focus on the synergies of pseudo-differential operators with applications, especially real-life applications, enhances understanding of the analysis and the usefulness of these operators.

Finding descriptive titles for books devoted to central issues in philosophy can often become a problem; it is very difficult to be original. Thus the title that I have given to this book is far from novel, having already been used several times by other authors. Nevertheless, I think that I can fairly claim to have employed it in a way that no one else has done before. Concerning my subtitle, some comments are in order. I have added it to emphasize my views regarding the nature and scope of epistemology. In particular, I wish to draw attention to the fact that I conceive its subject matter quite broadly. Rather than equating it, as is often done, with "theory of knowledge," I believe that epistemology should concern itself with the philosophical investigation of human belief in general. The two categories of human belief of most importance to the epistemologist are knowledge and what I shall call in the book "reasonable belief. " In my opinion a complete epistemology must take account of both, attempting to resolve the problems that are peculiar to each. For reasons that I give in the book I believe that knowledge and its problems must be the first concern of the epistemologist. Only after he has developed a satisfactory theory of knowledge can he tum, with any hope of success, to the formu lation of a theory of reasonable belief.
