Introduction

Jean Petitot is a polyhedric thinker whose contributions has been fundamental in a number of disciplines, such as epistemology, morphodynamics, differential geometry, structural semiotics, neurogeometry, phenomenology, linguistics, cognitive grammars, the theory of catastrophes, social sciences, literary studies and aesthetics. This book is a homage to his huge contribution about the main concepts of morphogenesis and meaning, that constitute the center of gravity around which Petitotian reflection revolves and returns. This chapter is just an introduction to the topic and to the brilliant contributions of authors who have accepted the invitation to take part to this tribute. An extended bibliography of Petitot works is included.
