Logic is an important field of research with many aspects. In this talk we will discuss in particular the difference between logic as reasoning and logic as a theory about reasoning. In the light of this distinction we will examine the unfolding of logic into logic and metalogic, the proliferation of logic systems, the question of the relativity and the universality of logic and the place and interaction of logic with regards to other sciences such as mathematics, semiotics and computer science.
