Summary

This chapter offers a meta-level analysis in the sociology and history of physics in the context of the “Arrow of Time” or the so-called Two Times problem. In effect, it argues that the two topics are intertwined, and it is only by coming to grips with the sociological aspects, involving adherence to certain metaphysical, epistemological, and methodological assumptions. Our argument is that the so-called Arrow of Time Problem or Two Times Problem (TTP) is essentially a myth. It is an article of faith that is contradicted by actual theoretical practice, in which the applicable physical theory does possess an Arrow of Time and must do so in order to account for the propagation of real energy and other conserved currents. Belief in the TTP is upheld only through entrenched adherence to a set of primarily metaphysical beliefs of a predominant Received View of physics that themselves are contradicted by the empirical facts, by current theory, and by inconsistencies among the beliefs themselves.
