The idea is that to grasp an idea like equality or justice, you can't look at the equal and just or unjust things in the world around you, you have to somehow ascend to or maybe remember some kind of idea of equality and justice and this would be a Platonic form, and it would be different from the things that partake in the form.
Peter AdamsonUnlike later Neo-Platonists, Plotinus says that our souls are always connected to the universal intellect and that we never really fall away.
Peter AdamsonWho you really are, is an immaterial soul and the body is an external thing that's sort of an encrustation your soul. So this has important implications for Plotinus' ethics, because his ethics are basically all about encouraging us to turn away from the body and turn towards these higher principles, so universal soul, universal intellect and ultimately the One.
Peter AdamsonPlotinus, when he thinks about mind or intellect, the Greek word is 'nous', he thinks about something that's very different, it's much more elevated and special, more abstract, you might say more philosophical than the very broad range of mental events that we talk about in contemporary philosophy of mind.
