Plotinus' power account of perception: Ennead IV.6.2

The paper provides a close reading of Plotinus' obscure chapter Ennead IV.6.2. I try to make clear, beyond the central thesis that sense-perception is an active power, how it contributes to the argument of the whole treatise, how its seemingly disconnected comments make up a coherent line of thought, and how it remains consistent with Plotinus' positions expressed elsewhere.
