SEMIOTIC SOCIOLOGY (SESO) is a book plan based on the following consideration. The cultural current that at the turn of the 19th century gave birth to the three basic modern social sciences of economics, political science and sociology that all study ‘us’ in the deluge called ‘modernity’ and to anthropology that studies ‘them’ in the wake of colonialism, the other side of the coin called ‘modernity’, somehow managed to bypass semiotics. This is a weird thing because one would imagine that in an era that many have for a good reason called the ‘time of communication’ or the ‘time of the sign’ there would be great demand for a discipline studying the general patterns of signification. In some sense, this general discipline did emerge because the time gave birth to a great deal of semiotic conceptions, including the Saussurean tradition of semiology and the Peircean tradition of semiotics. Yet semiotics has always been flooded with too many conceptions that have too often been thought to be contradictory, as is often said about the relationship between the structuralist and the pragmaticist tradition. The discipline, therefore, has not managed to be consolidated but has been left into the state of hesitation and anomie. This book is an attempt to construct a synthetic conception covering the pragmaticist and the structuralist tradition and extending within social theory to the fields of phenomenological sociology and action theory as well.
