Psyllium is a fiber supplement, used primarily for the treatment of constipation due to its being a good source of soluble fiber. As a supplement, psyllium is derived from the seed husks of a plant called Plantago ovata.
Social theory is interdisciplinary and draws upon ideas from fields as diverse as anthropology and media studies. Social theory of an informal nature, or authorship based outside of academic social and political science, may be referred to instead as  social criticism  or  social commentary .
The most systematic modern attempt to resolve this question is found in the writings of Parsons (1938-1953; 1951; 1960; 1966). In Parsonsâ view, sociological theory is an aspect of the theory of social systems and sociology is thereby defined as a special social science.ociology, for Durkheim, was the study of âsocial facts,â and it should not be forgotten that his first major work after completing his French and Latin theses was The Rules of Sociological Method [1895; for a discussion of Durkheimâs conception of social facts, see the biography of Durkheim].
