The book aims to provide a process-philosophical perspective philosophizing itself. It employs the perspectives of process philosophy for elucidating the historical development of philosophical ideas. The doctrine of historicism in the history of ideas has it that each era and perhaps even each thinker employs philosophical ideas in such a user-idiosyncratic way that there is no continuity and indeed no connectivity of public access across the divides of space, time, and culture. In opposition to such a view, the present processist deliberations see the development of ideas as a matter of generic processes that have ample room for connectivity and recurrence, permitting the very self-same conception to be shared by philosophers of different settings. Beyond arguing this histico-processism on general principles, the book presents a series of case studies of significant philosophical topics that illustrate and elaborate upon the developmental connectivities at issue.
