A highly influential work in the history of philosophy of mind and language.

Condillac's Essay on the Origin of Human Knowledge, first published in French in 1746 and offered here in a new translation, represented in its time a radical departure from the dominant conception of the mind as a reservoir of innately given ideas. Descartes had held that knowledge must rest on ideas; Condillac turned this upside down by arguing that speech and words are the origin of mental life and knowledge. His work influenced many later philosophers, and also anticipated Wittgenstein's view of language and its relation to mind and thought.

First published in 1689, John Locke's Essay Concerning Human Understanding is widely recognised as among the greatest works in the history of Western philosophy. The Essay puts forward a systematic empiricist theory of mind, detailing how all ideas and knowledge arise from sense experience. Locke was trained in mechanical philosophy and he crafted his account to be consistent with the best natural science of his day. The Essay was highly influential and its rendering of empiricism would become the standard for subsequent theorists. This Companion volume includes fifteen new essays from leading scholars. Covering the major themes of Locke's work, they explain his views while situating the ideas in the historical context of Locke's day and often clarifying their relationship to ongoing work in philosophy. Pitched to advanced undergraduates and graduate students, it is ideal for use in courses on early modern philosophy, British empiricism and John Locke.

"An Enquiry Concerning Human Understanding" is a book by David Hume created as a revision of an earlier work, Hume's "A Treatise of Human Nature". The argument of the Enquiry proceeds by a series of incremental steps, separated into chapters which logically succeed one another. After expounding his epistemology, Hume explains how to apply his principles to specific topics. This book has proven highly influential, both in the years that would immediately follow and today. Immanuel Kant points to it as the book which woke him from his self-described "dogmatic slumber."

Examines humanistic aspects of astrobiology, exploring approaches, critical issues, and implications of the discovery of extraterrestrial life.

John Locke was one of the greatest figures of the Enlightenment, whose assertion that reason is the key to knowledge changed the face of philosophy. These writings on thought, ideas, perception, truth and language are some of the most influential in the history of Western thought. Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.
