In this paper we shall open a perspective from which the relatedness between the early analytic philosophy and Husserl’s phenomenology is so close that we can call the two programs with one name: “rigorous philosophy”, or “theory of forms”. Moreover, we shall show that the close relatedness between the two most influential philosophical movements of the 20th century has its roots in their common history. At the end of the paper we shall try to answer the question why being rather (...) related at the beginning, their ways parted in the subsequent years. (shrink)
