H. Reichenbach is cited as bibliography entry 1 in N. A. Kozyrev's September 1967 paper: The Direction of Time, 1956, Berkeley. Kozyrev invokes Reichenbach (together with G. J. Whitrow) on the tautology problem in defining the direction of time through causality — the difficulty that using causal order to define time direction risks circularity.
The source cites the work only as intellectual context; it does not reproduce or engage with Reichenbach's argument in detail. See Time Directivity.
