2. the theory that the self is a bundle of successive perceptions rather than a unified substance or entity
3. uniformitarianism sense 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.
