The Reliability of Sense Perception

Why suppose that sense perception is an accurate source of information about the physcial environment? More generally, is it possible to demonstrate that our basic ways of forming beliefs are reliable? In this book, a leading analytic philosopher confronts this classic problem through detailed investigation of sense perception, the source of beliefs in which we place the most confidence. Carefully assessing the available arguments, William P. Alston concludes that it is not possible to show in any noncircular way that sense perception is a reliable source of beliefs.
