This book presents a nonstandard approach to epistemology. Where standard epistemology generally focuses on the certain knowledge the Greeks called epistêmê, the present focus is on some less assured modes of information. Its deliberations focus on such cognitively suboptimal processes as conjecture, guesswork, and plausible supposition.
