"Modern philosophy begins with Descartes. The problems he introduced and attempted to solve formed the core of subsequent philosophical inquiry. In the first half of the book Aune considers the history of the problem of the external world in the work of the great modern philosophers, Descartes, Locke, Berkeley, Kant and Mill. Then turning to current debates he argues that the problem has re-emerged, and he undertakes a revision of empiricist epistemology and the development of the required theory of inference. He bases the logical structure of the latter on the probability calculus and on a conception of justifiable belief formation. Knowledge of the External World is an excellent historical systematic analysis of a central problem of philosophy and provides a fine introduction to the theory of knowledge."
"Aune disagrees that Wittgenstein has made the traditional philosophical problem of knowledge of the external world redundant. After a survey of the classic modern philosophers' views on the subject Aune offers his own original solution."@en
