While the discussions of Husserl's theory of signs and of meaning are many, we hope to break new ground in these first few chapters by introducing the development of hus ideas in one of his lecture manuscripts between 1905 and 1908 and by discussing his own critical evaluation of the distinctions which he first proposed.¹ We detect in this text some interesting shifts in his initial definition of ecpression and even in his concept of intentionality. The former will be handled in this this chapter while latter will be treated in Chapter Two and Three.
