actualism

1 :  a philosophical doctrine that all existence is active or spiritual, not inert or dead, or that reality is founded on activity or consists of process

2 :  the theory that the self is a bundle of successive perceptions rather than a unified substance or entity

3 geology :  uniformitarianism 1 But a uniformity of causes does not imply a uniformity of rates, intensities, conditions, or results. … Some people consider actualism a better term than uniformitarianism. Processes that actually operate now, or those inferred to operate, can explain features and events of the past. — Alan M. Cvancara, A Field Manual For The Amateur Geologist, 1995
