ABSTRACT
Reductive phenomenalism has to recognize a form of time which is logically independent of the physical world. Subjective and inter-subjective (IS) time are different forms of mental time. The strategy will be developed in accordance with three fundamental principles, which concern the relationship between IS-time and the elements (subjective time-order, subjective distance and IS causation) out of which it is to be constructed. If we are to construct IS time out of subjective time and IS causation, we have to envisage causal lines running from an event in one mind to an event in another. However, for the purposes of constructing IS-time, it will be convenient to assign to each mind a subjective time-dimension and to introduce an ontology of subjective moments and periods drawn from such dimensions. Defined, subjective time seems to be something which could, given an appropriate ultimate reality, obtain pre-physically and thus contribute, as the phenomenalist requires, to the creation of the physical world.
