Modern times show a deeply rooted fascination for signs. Philosophers like Charles Sanders Peirce already registered that change of mind at the edge of the 20th century. He inspired Roberta Kevelson in her design of a method of knowledge seeking and questioning. She applied in that method many "How's of "Why" and "Why's of "How" in Law and the Legal Sciences. It formed the basis for unfolding the concept of legal semiotics. The latter highlighted new insights on signs in legal practice and in legal education.
