The Rationality Of Perception

There is an important division in the human mind between perception and reasoning. We reason from information that we have already, but perception is a means of taking in new information. Susanna Siegel argues that these two aspects of the mind become deeply intertwined when beliefs, fears, desires, or prejudice influence what we perceive.

In this urbane and witty book, Ronald de Sousa disputes the widespread notion that reason and emotion are natural antagonists. He argues that emotions are a kind of perception, that their roots in the paradigm scenarios in which they are learned give them an essentially dramatic structure, and that they have a crucial role to-play in rational beliefs, desires, and decisions by breaking the deadlocks of pure reason.The book's twelve chapters take up the following topics: alternative models of mind and emotion; the relation between evolutionary, physiological, and social factors in emotions; a taxonomy of objects of emotions; assessments of emotions for correctness and rationality; the regulation by emotions of logical and practical reasoning; emotion and time; the mechanism of emotional self-deception; the ethics of laughter; and the roles of emotions in the conduct of life. There is also an illustrative interlude, in the form of a lively dialogue about the ideology of love, jealousy, and sexual exclusiveness. A Bradford Book.

How to assess critical aspects of cognitive functioning that are not measured by IQ tests: rational thinking skills. Why are we surprised when smart people act foolishly? Smart people do foolish things all the time. Misjudgments and bad decisions by highly educated bankers and money managers, for example, brought us the financial crisis of 2008. Smart people do foolish things because intelligence is not the same as the capacity for rational thinking. The Rationality Quotient explains that these two traits, often (and incorrectly) thought of as one, refer to different cognitive functions. The standard IQ test, the authors argue, doesn't measure any of the broad components of rationality—adaptive responding, good judgment, and good decision making. The authors show that rational thinking, like intelligence, is a measurable cognitive competence. Drawing on theoretical work and empirical research from the last two decades, they present the first prototype for an assessment of rational thinking analogous to the IQ test: the CART (Comprehensive Assessment of Rational Thinking). The authors describe the theoretical underpinnings of the CART, distinguishing the algorithmic mind from the reflective mind. They discuss the logic of the tasks used to measure cognitive biases, and they develop a unique typology of thinking errors. The Rationality Quotient explains the components of rational thought assessed by the CART, including probabilistic and scientific reasoning; the avoidance of “miserly” information processing; and the knowledge structures needed for rational thinking. Finally, the authors discuss studies of the CART and the social and practical implications of such a test. An appendix offers sample items from the test.

What do we see? We are visually conscious of colors and shapes, but are we also visually conscious of complex properties such as being John Malkovich? In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of complex properties. Siegel starts by analyzing the notion of the contents of experience, and by arguing that theorists of all stripes should accept that experiences have contents. She then introduces a method for discovering the contents of experience: the method of phenomenal contrast. This method relies only minimally on introspection, and allows rigorous support for claims about experience. She then applies the method to make the case that we are conscious of many kinds of properties, of all sorts of causal properties, and of many other complex properties. She goes on to use the method to help analyze difficult questions about our consciousness of objects and their role in the contents of experience, and to reconceptualize the distinction between perception and sensation. Siegel's results are important for many areas of philosophy, including the philosophy of mind, epistemology, and the philosophy of science. They are also important for the psychology and cognitive neuroscience of vision.

How can human beings, who are liable to error, possess knowledge, since the grounds on which we believe do not rule out that we are wrong? Andrea Kern argues that we can disarm this skeptical doubt by conceiving knowledge as an act of a rational capacity. In this book, she develops a metaphysics of the mind as existing through knowledge of itself.

Medieval Perceptual Puzzles: Theories of Sense Perception in the 13th and 14th Centuries is an anthology of texts offering an in-depth analysis of Latin medieval theories of sense-perception. The volume offers historical and systematic approaches to themes and questions that have shaped the medieval accounts of sense-perception.

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.

Extended Rationality provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein's idea that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address problems such as scepticism and relativism.
