Abstract

This paper expresses certain qualms about causal theories of time, Such as have been put forward by h. Mehlberg and adolf gruenbaum. These qualms arise from doubts about the clarity of the notion of causality. It is suggested that a metalinguistic concept of causality cannot occur within the object language of physics, And that any non-Metalinguistic concept of causality leads to more difficulties than do the concepts of physical geometry which a causal theory of time is supposed to elucidate
