The article analyzes new approaches that the conceptual history has taken to the history of science. These include the interconnection of the conceptual history, metaphorology, and object history, as well as the increasing interweaving of the history of science with social, political, and communication history. These shifts in the boundaries between different fields give new relevance to Reinhart Koselleck’s approach to the conceptual history. The final part of the paper addresses a number of views, questions and perspectives of a conceptual history after Koselleck.
