This book presents twenty essays by Nicholas Rescher, representing more than a decade of his work. The first part of the collection offers thoughts on the history of philosophy from the Presocratics to the twentieth century; the second part features essays on epistemology, the philosophy of science, metaphysics, the theory of historiography, and the logic of temporal concepts. Despite the range of topics, all essays are closely integrated at the methodological level.

This groundbreaking new source of international scope defines the essay as nonfictional prose texts of between one and 50 pages in length. The more than 500 entries by 275 contributors include entries on nationalities, various categories of essays such as generic (such as sermons, aphorisms), individual major works, notable writers, and periodicals that created a market for essays, and particularly famous or significant essays. The preface details the historical development of the essay, and the alphabetically arranged entries usually include biographical sketch, nationality, era, selected writings list, additional readings, and anthologies
