Introduction

Abstract

As it was expressed in the Introduction to our first volume, in order to clarify the discussions surrounding the unity of science, a sharp distinction between science unity and science unification should be drawn. Whereas the former only demands tasks for the identification of common factors among the diverse disciplines - mainly objects and methods - the latter involves the determination of those formal and material conditions that make the connections between theories really possible. It is of paramount importance to take into account that both conditions should allow for an effective connection between theories.
