Plausible Worlds : Possibility and Understanding in History and the Social Sciences

Possibilities haunt history. The force of our explanations of events turns on the alternative possibilities these explanations suggest.

His conclusions cast doubt on existing assumptions about the nature and place of theory, and indeed of the possibility of knowledge itself, in the human sciences.
