Plotinus is a neo-Platonist, so he would encourage us to go back to Plato.

The world around you is some kind of distraction at best, and evil at worst, and you should be turning away from it.

The intellect must be different from the soul.

For Plotinus, what really exists are the Platonic forms, so the true nature or form of things like justice, beauty, maybe numbers, things like that, and these he associates with the intellect because they're the objects of intellect, they are things that intellect can think about.

Plotinus, 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.

The importance of Plotinus is not only his own philosophical ideas which are quite interesting, but his historical impact as the founder of neo-Platonism which is the main philosophical tradition of late antiquity.

We do each have an intellect but there's a universal intellect which is the same for everybody, as it were. And this single intellect is grasping the platonic forms.
