Abstract

It is made clear what discursive knowledge is and how we acquire it, and some age-old skeptical views are shown to be incoherent. It is shown that all knowledge is to some degree inferential. At the same time, it is shown that there are three quite distinct senses in which empirical knowledge can be inferential. It is proved that we have a priori knowledge, and also that knowledge of non-empirical truths is needed to acquire empirical knowledge. Finally, it is clearly explained what prediction is, what explanation is, how the two differ, and how they are similar.
