Abstract

Vivacity, the “liveliness” of perceptions, is central to Hume’s epistemology. Hume equated belief with vivid ideas. Vivacity is a conscious quality so believable ideas are felt to be lively. Hume’s empiricism revolves around a phenomenological, inner epistemology. Through copying, Hume bases vivacity in impressions. Sensory vivacity also concerns liveliness or patterns of change. Through learnt skillful use, it tracks change specific to intentional sense-perceptual experience, Hume’s “coherent and constant” complex impressions. Copying, in turn, communicates the conscious skill of vivacity to ideas where it becomes an indicator of believable ideas. Hume’s copying concerns then the causation of conscious skills required for the identification of empirically warranted structures. Copying allows Hume to combine a radically externalist empiricism with a portable phenomenological inner epistemology.
