Rationality In Context

A TIMES BOOK OF THE YEAR 2021 'Punchy, funny and invigorating ... Pinker is the high priest of rationalism' Sunday Times 'If you've ever considered taking drugs to make yourself smarter, read Rationality instead. It's cheaper, more entertaining, and more effective' Jonathan Haidt, author of The Righteous Mind In the twenty-first century, humanity is reaching new heights of scientific understanding - and at the same time appears to be losing its mind. How can a species that discovered vaccines for Covid-19 in less than a year produce so much fake news, quack cures and conspiracy theorizing? In Rationality, Pinker rejects the cynical cliché that humans are simply an irrational species - cavemen out of time fatally cursed with biases, fallacies and illusions. After all, we discovered the laws of nature, lengthened and enriched our lives and set the benchmarks for rationality itself. Instead, he explains, we think in ways that suit the low-tech contexts in which we spend most of our lives, but fail to take advantage of the powerful tools of reasoning we have built up over millennia: logic, critical thinking, probability, causal inference, and decision-making under uncertainty. These tools are not a standard part of our educational curricula, and have never been presented clearly and entertainingly in a single book - until now. Rationality matters. It leads to better choices in our lives and in the public sphere, and is the ultimate driver of social justice and moral progress. Brimming with insight and humour, Rationality will enlighten, inspire and empower. 'A terrific book, much-needed for our time' Peter Singer

Rationality: Contexts and Constraints is an interdisciplinary reappraisal of the nature of rationality. In method, it is pluralistic, drawing upon the analytic approaches of philosophy, linguistics, neuroscience, and more. These methods guide exploration of the intersection between traditional scholarship and cutting-edge philosophical or scientific research. In this way, the book contributes to development of a suitably revised, comprehensive understanding of rationality, one that befits the 21st century, one that is adequately informed by recent investigations of science, pathology, non-human thought, emotion, and even enigmatic Chinese texts that might previously have seemed to be expressions of irrationalism. Addresses recent challenges and Identifies a direction for future research on rationality Investigates the relationship between rationality and mental disorders, such as delusion and depression Assesses reasoning in artificial intelligence and nonhuman animals Reflects on ancient Chinese Philosophy and possible cultural differences in human psychology Employs philosophical reflection, along with linguistic, probabilistic, and logical techniques

Interactive Minds harnesses both research and theory from several disciplines to study cognitive development in the social context of the life course.

The word ‘rationality’ and its cognates, like ‘reason’, have multiple contexts and connotations. Rational calculation can be contrasted with rational interpretation. There is the rationality of proof and of persuasion, of tradition and of the criticism of tradition. Rationalism (and rationalists) can be reasonable or unreasonable. Reason is sometimes distinguished from revelation, superstition, convention, prejudice, emotion, and chance, but all of these also involve reasoning. In politics, three views of rationality – economic, moral, and historical – have been especially important, often defining approaches to politics and political theory such as utilitarianism and rational choice theory. These approaches privilege positive or natural law, responsibilities, or human rights, and emphasize the importance of culture and tradition, and therefore meaning and context. This book explores the understanding of rationality in politics and the relations between different approaches to rationality. Among the topics considered are the limits of rationality, the role of imagination and emotion in politics, the meaning of political realism, the nature of political judgment, and the relationship between theory and practice. This book was originally published as a special issue of Global Discourse.

This book is concerned with situations in which several persons reach decisions independently and the final consequence depends, potentially, upon each of the decisions taken. Such situations may be described formally by an extensive form game: a mathematical object which specifies the order in which decisions are to be taken, the information available to the decision makers at each point in time, and the consequence that results for each possible combination of decisions. A necessary requirement for rational behavior in such games is that each decision maker should reach a decision that is optimal, given his preferences over his own decisions. This requirement is far from sufficient, however, since every decision maker should in addition base his preferences upon the conjecture that his opponents will act optimally as well. It is this principle that distinguishes noncooperative game theory from one-person decision theory. The main purpose of Rationality in Extensive Form Games is to discuss different formalizations of this principle in extensive form games, such as backward induction, Nash equilibrium, forward induction and rationalizability, under the assumption that the decision makers' preferences are given by subjective expected utility functions. The various formalizations, or rationality criteria, are illustrated by examples, and the relationships among the different criteria are explored.

In the Enlightenment tradition, rationality is considered well-defined. However, the author of this study argues that rationality is context-dependent, and that the crucial context is determined by decision-makers' political power. He uses a real-world Danish project to illustrate this theory.

Professor Brown describes and criticises the major classical model of rationality and offers a new model of this central concept in the history of philosophy and of science.

Ralph Wedgwood gives a general account of what it is for states of mind and processes of thought to count as rational. Whether you are thinking rationally depends purely on what is going on in your mind, but rational thinking is a means to the goal of getting things right in your thinking, by believing the truth or making good choices.
