Enneads VI.3: Plotino's Own Sense-Categories
Movement Is More Than the Negation of Rest
It may perhaps be asked, why is movement not rather the negation of rest? We shall then answer that movement (is something positive), that it brings something with it; that it has some efficiency, that it communicates an impulsion to the subject, that produces or destroys many things; stillness, on the contrary, is nothing outside of the subject which is still, and means no more than that the latter is still.
