This book explores a question central to philosophy--namely, what does it take for a belief to be justified or rational? According to a widespread view, whether one has justification for believing a proposition is determined by how probable that proposition is, given one's evidence. In this book this view is rejected and replaced with another: in order for one to have justification for believing a proposition, one's evidence must normically support it--roughly, one's evidence must make the falsity of that proposition (...) abnormal in the sense of calling for special, independent explanation. This conception of justification bears upon a range of topics in epistemology and beyond. Ultimately, this way of looking at justification guides us to a new, unfamiliar picture of how we should respond to our evidence and manage our own fallibility. This picture is developed here.

It is well known that Husserl considered phenomenology to be First Philosophy—the ultimate science. For Husserl, this means that phenomenology must clarify the ultimate phenomenological-epistemological principle that leads to ultimate elucidation. But what is this ultimate principle and what does ultimate elucidation mean? It is the aim of this paper to answer these questions. In section 2, we shall discuss what role Husserl’s principle of all principles can play in the quest for ultimate elucidation and what it means for a (...) principle to be ultimately elucidating and ultimately elucidated. We will see that the Husserlian thesis that originary presentive intuitions are an immediate and the ultimate source of justification qualifies as the ultimate epistemological principle. (shrink)
