Broadly speaking, this is a book about truth and the criteria thereof.
Thus it is, in a sense, a book about justification and rationality. But
it does not purport to be about the notion of justification or the
notion of rationality. For the assumption that there is just one notion
of justification, or just one notion of rationality, is, as the book
explains, very misleading. Justification and rationality come in various
kinds. And to that extent, at least, we should recognize a variety of
notions of justification and rationality. This, at any rate, is one of
the morals of Chapter VI. This book, in Chapters I-V, is mainly
concerned with the kind of justification and rationality characteristic
of a truth-seeker, specifically a seeker of truth about the world
impinging upon the senses: the so-called empirical world. Hence the
book's title. But since the prominent contemporary approaches to
empirical justification are many and varied, so also are the
epistemological issues taken up in the following chapters. For instance,
there will be questions about so-called coherence and its role, if any,
in empirical justification. And there will be questions about social
consensus (whatever it is) and its significance, or the lack thereof, to
empirical justification. Furthermore, the perennial question of whether,
and if so how, empirical knowledge has so-called founda- tions will be
given special attention.
