This is a long-awaited new edition of one of the best known Oxford Logic Guides. The book gives an informal but thorough introduction to intuitionistic mathematics, leading the reader gently through the fundamental mathematical and philosophical concepts. The treatment of various topics has been completely revised for this second edition. Brouwer's proof of the Bar Theorem has been reworked, the account of valuation systems simplified, and the treatment of generalized Beth Trees and the completeness of intuitionistic first-order logic rewritten. Readers are assumed to have some knowledge of classical formal logic and a general awareness of the history of intuitionism.

This debut novel by the two time Pulitzer Prize-winning author of The Underground Railroad and The Nickel Boys wowed critics and readers everywhere and marked the debut of an important American writer. Nominated as one of America’s best-loved novels by PBS’s The Great American Read. It is a time of calamity in a major metropolitan city's Department of Elevator Inspectors, and Lila Mae Watson, the first black female elevator inspector in the history of the department, is at the center of it. There are two warring factions within the department: the Empiricists, who work by the book and dutifully check for striations on the winch cable and such; and the Intuitionists, who are simply able to enter the elevator cab in question, meditate, and intuit any defects. Lila Mae is an Intuitionist and, it just so happens, has the highest accuracy rate in the entire department. But when an elevator in a new city building goes into total freefall on Lila Mae's watch, chaos ensues. It's an election year in the Elevator Guild, and the good-old-boy Empiricists would love nothing more than to assign the blame to an Intuitionist. But Lila Mae is never wrong. The sudden appearance of excerpts from the lost notebooks of Intuitionism's founder, James Fulton, has also caused quite a stir. The notebooks describe Fulton's work on the "black box," a perfect elevator that could reinvent the city as radically as the first passenger elevator did when patented by Elisha Otis in the nineteenth century. When Lila Mae goes underground to investigate the crash, she becomes involved in the search for the portions of the notebooks that are still missing and uncovers a secret that will change her life forever. Look for Colson Whitehead’s new novel, Crook Manifesto, coming soon!

In this 2005 book, logic, mathematical knowledge and objects are explored alongside reason and intuition in the exact sciences.

Within the Western tradition, it was the philosophers Henri Bergson and Max Scheler who laid out and explored the nonrational power of "intuition" at work in human beings that plays a key role in orienting their thinking and action within the world. As author Adriana Alfaro Altamirano notes, Bergon's and Scheler's philosophical explorations, which paralleled similar developments by other modernist writers, artists, and political actors of the early twentieth century, can yield fruitful insights into the ideas and passions that animate politics in our own time. The Belief in Intuition shows that intuition (as Bergson and Scheler understood it) leads, first and foremost, to a conception of freedom that is especially suited for dealing with hierarchy, uncertainty, and alterity. Such a conception of freedom is grounded in a sense of individuality that remains true to its "inner multiplicity," thus providing a distinct contrast to and critique of the liberal notion of the self. Focusing on the complex inner lives that drive human action, as Bergson and Scheler did, leads us to appreciate the moral and empirical limits of liberal devices that mean to regulate our actions "from the outside." Such devices, like the law, may not only carry pernicious effects for freedom but, more troublingly, oftentimes "erase their traces," concealing the very ways in which they are detrimental to a richer experience of subjectivity. According to Alfaro Altamirano, Bergson's and Scheler's conception of intuition and personal authority puts contemporary discussions about populism in a different light: It shows that liberalism would only at its own peril deny the anthropological, moral, and political importance of the bearers of charismatic authority. Personal authority thus understood relies on a dense, but elusive, notion of personality, for which personal authority is not only consistent with freedom, but even contributes to it in decisive ways.

Rational Intuition explores the concept of intuition as it relates to rationality through mediums of history, philosophy, cognitive science, and psychology.

"This book is intended for readers who, while mature mathematically, have no knowledge of mathematical logic. We attempt to introduce the reader to the most important approaches to the subject, and, wherever possible within the limitations of space which we have set for ourselves, to give at least a few nontrivial results illustrating each of the important methods for attacking logical problems"--Preface.
