What collection of papers by a Russian-British social and political theorist appeared in 1969?
Isaiah Berlin Sir Isaiah Berlin (6 June 1909 – 5 November 1997) was a Russian-British social and political theorist, philosopher and historian of ideas. He was an essayist, conversationalist, raconteur, and lecturer. In its obituary of the scholar, the "Independent" stated that "Isaiah Berlin was often described, especially in his old age, by means of superlatives: the world's greatest talker, the century's most inspired reader, one of the finest minds of our time [...] there is no doubt that he showed in more than one direction the unexpectedly large possibilities open to us at the top end of the range of human potential".
Frederic Bartlett Sir Frederic Charles Bartlett FRS (20 October 1886 – 30 September 1969) was a British psychologist and the first professor of experimental psychology at the University of Cambridge. He was one of the forerunners of cognitive psychology. Bartlett considered most of his own work on cognitive psychology to be a study in social psychology, but he was also interested in anthropology, moral science, philosophy, and sociology. Bartlett proudly referred to himself as "a Cambridge Psychologist" because while he was at the University of Cambridge, settling for one type of psychology was not an option.
