Originally published in 1961. Greek philosophers were concerned with the distinction between appearance and reality, and all the differences in their philosophic systems were ultimately predicated on their different views of this distinction. The history of Greek rationalism is, then, a study of the changing basis of Greek philosophy. George Boas provides a historical account of rationalism in classical philosophy. He focuses on four central topics: the distinction between appearance and reality, the method used to establish the distinction, the appraisal of life made by the philosophers studied, and their ethical theories.

Evaluation is central to literary studies and has led to an impressive list of publications on the status and history of the canon. Yet it is remarkable how little attention has been given to the role of textual properties in evaluative processes. Most of the chapters in The Quality of Literature redress this issue by dealing with texts or genres ranging from classical antiquity, via Renaissance to twentieth century. They provide a rich textual and historical panorama of how critical debate over literary quality has influenced our modes of thinking and feeling about literature, and how they continue to shape the current literary landscape. Four theoretical chapters reflect on the general state of literary evaluation while the introduction weaves the different threads together aiming at further conceptual clarification. This book thus contributes to a deeper understanding of the problems that are at the heart of past and present debates over literary quality.
A groundbreaking account of perception and art, from one of the twentieth century’s most important art historians E. H. Gombrich is widely considered to be one of the most influential art historians of the twentieth century, and Art and Illusion is generally agreed to be his most important book. Bridging science and the humanities, this classic work examines the history and psychology of pictorial representation in light of modern theories of information and learning in visual perception. Searching for a rational explanation of the changing styles of art, Gombrich reexamines ideas about the imitation of nature and the function of tradition. In testing his arguments, he ranges over the history of art, from the ancient Greeks, Leonardo, and Rembrandt to the impressionists and the cubists. But the triumphant originality of Art and Illusion is that Gombrich is less concerned with the artists than with the psychological experience of the viewers of their work.
