The history of ideas deals with the elemental unit-ideas which for Lovejoy are components of systems distinguished by their patterns. Special histories explain how a particular form of human history developed. General histories draw on special histories to document or explain social contexts. Since patterns influence philosophers, the history of ideas contributes little to the history of philosophy, a discontinuous strand within a period's continuous intellectual history. By accepting cultural pluralism, denying the monistic position that there always are internal connections (...) among all or some strands of intellectual and cultural history, both continuity and change in philosophy can be best understood.
