​This volume offers a new understanding of Titchener influential system of psychology popularly known as introspectionism, structuralism and as classical introspective psychology. Adopting a new perspective on introspectionism and seeking to assess the reasons behind its famous implosion, this book reopens and rewrites the chapter in the history of early scientific psychology pertaining to the nature of E. B. Titchener psychological system.   Arguing against the view that Titchener system was undone by an overreliance on introspection, the author explains how this idea was first introduced by the early behaviorists in order to advance their own theoretical agenda. Instead, the author argues that the major philosophical flaw of introspectionism was its utter reliance on key theoretical assumptions inherited from the intellectual tradition of British associationism—assumptions that were upheld in defiance of introspection, not because of introspection.   The book is divided into three parts. In Part I, British associationism is examined thoroughly. The author here discusses the psychology of influential empiricist philosophers such as Thomas Hobbes, John Locke, David Hume, David Hartley, James Mill, and John Stuart Mill. In Part II of the book, Titchener introspectionist system of psychology is examined and analyzed. In Part III, the author argues that Titchener psychology should be understood as a form of associationism and explains how analysis, not introspection, was central to introspectionism.
