A very learned book, weaving together themes from many literatures, and must represent decades of reading and reflection. (Sobrinho) makes a valuable contribution in showing the congruence between Peirce's 'scientific realism' and Durkheim's social processes of moral and cognitive solidarity.

Signs, Solidarities, and Sociology is an insightful and multiply informed book that reflects much reading and much thought.

Nicholas Rescher

Sobrinho's commentary on contemporary social thought is wide-ranging and eclectic, yet informed by a coherent and original perspective. This is the best new book on social theory to have come my way in a long time.
