The theory of social representations must be understood in terms of its proper epistemology so that it can accomplish its full potential in social sciences. This is often difficult to achieve because researchers comprehend it in terms of concepts that are part of static and individualistic Newtonian epistemology rather than in terms of dynamic and relational Einsteinian epistemology. This article considers three signposts that Moscovici identifies and analyses in the theory of relativity, namely the relation between epistemology and science, theory (...) and method, and the argument against the explanation of effects by their causes. The following question is posed: are these signposts also characteristic of the theory of social representations? This question is examined focusing on interactional epistemology, theory and method and the diversity of natural thinking and communication. Moscovici's Psychoanalysis shows that natural thinking appears in a plurality of modes according to the situation in which it takes place and according to social groups towards which it is directed. Natural thinking is controversial and communication-centred. Different professionals, groups and lay people use different kinds of speaking and different communicative genres when they try to resolve “the same” problem. The article suggests that bringing together dialogicality, dialogical linguistics and the theory of social representations may open up new possibilities for theoretical developments in social psychology.

‘‘The strange Story of the Concept which inaugurated Modern Theoretical Physics’’ is the title of a lecture which I delivered on the invitation of Professor Franco Selleri at the University of Bari about 20 years ago. Since Professor Selleri himself has written several interesting papers on this concept and since the centennial of the birth of modern theoretical physics will be celebrated soon, I found it appropriate to dedicate this essay, containing so far unpublished critical and historical comments on this (...) concept, to Professor Selleri on the occasion of his 70th birthday. It should be emphasized that the critical comments in this essay are not intended to question the validity of the theory initiated by this concept, a theory which in the realm of its applicability is daily corroborated by numerous experiments in high-energy laboratories all over the world. Although these critical remarks refer almost exclusively to the first publication of this theory, a publication which has been hailed as ‘‘the most important paper written in the 20th century,’’ they discuss profound problems of general importance for the study of the foundations of physics.
