Development of research connected with artificial intelligence and the cognitive sciences obliges us to confront further components of the traditional problem of form. Contributors analyze the concept of form from the perspective of fields such as ontology, language, and mathematics, and look at form in its different aspects according to a more modern theory of knowledge. Subjects include experimental phenomenology, a theory of figural form, form metaphysics, and forms in algebras. Of interest to systematic philosophers, philosophers of language, psychologists, and linguists. Annotation copyrighted by Book News, Inc., Portland, OR

impossible triangle, after apprehension of the perceptively given mode of being of that 'object', the visual system assumes that all three sides touch on all three sides, whereas this happens on only one side. In fact, the sides touch only optically, because they are separate in depth. In Meinong's words, Penrose's triangle has been inserted in an 'objective', or in what we would today call a "cognitive schema". Re-examination of the Graz school's theory, as said, sheds light on several problems concerning the theory of perception, and, as Luccio points out in his contribution to this book, it helps to eliminate a number of over-simplistic commonplaces, such as the identification of the cognitivist notion of 'top down' with Wertheimer's 'von oben unten', and of 'bottom up' with his 'von unten nach oben'. In fact, neither Hochberg's and Gregory's 'concept-driven' perception nor Gibson's 'data-driven' perception coincide with the original conception of the Gestalt.

This book is about geometric shapes, widely used by graphic designers and applied to all the fields of communication.

While piloting his spaceship through the skies, Captain Invincible encounters three-dimensional shapes, including cubes, cylinders, and pyramids.

Unlike many other art books only give recipes for mixing colors or describe step-by-step painting techniques, *Color and Light* answers the questions that realist painters continually ask, such as: "What happens with sky colors at sunset?", "How do colors change with distance?", and "What makes a form look three-dimensional?" Author James Gurney draws on his experience as a plain-air painter and science illustrator to share a wealth of information about the realist painter's most fundamental tools: color and light. He bridges the gap between abstract theory and practical knowledge for traditional and digital artists of all levels of experience.
