Abstract

The philosophy of logical empiricism has largely determined the direction and the range of problems of the philosophy, which later became known as analytic philosophy. Philosophers of the Vienna Circle and their followers had to dissociate their program from other philosophies predominant in the early twentieth century (particularly from neo-Kantianism and neo-Hegelianism). As a part of this task the revision of the concepts of classical epistemology, including the concept of apriori was carried out. The paper examines how, in the framework of logical empiricism, apriority became identified with analyticity, and discusses alternative theories of the a priori, which resulted of this identification.
