'''''Protophysics of Time: Constructive Foundation and History of Time Measurement''''' is a book by the philosopher [[Peter Janich]], published in English in 1985 by D. Reidel as volume 30 of the ''Boston Studies in the Philosophy of Science'' (translated from the German ''Die Protophysik der Zeit'').

==Overview==

Janich develops a '''protophysics''' of time — a constructive, operational reconstruction of the foundations of time measurement in the tradition of Paul Lorenzen and the Erlangen School. Rather than taking metric time as given, he seeks to establish the theory of chronometry from the practical art of building and using clocks, giving a "constructive foundation" for the measurement of time and setting it against the history of time-keeping. The book includes an introductory essay by Paul Lorenzen on the "axiomatic and constructive method."

==About the author==

Peter Janich (1942–2016) was a German philosopher of science, a leading figure of the (Erlangen–Marburg) constructivist school, known for his "protophysics" program that seeks to ground the foundations of physics in the norms of measurement practice.
