We do have intellects and Plotinus controversially thought that even though we might not be aware of it, our souls are always connected to the intellect. They never fully descend as he would put it.

I'm sure that Plotinus wasn't that impressed by the Christians.

In fact one of the things about Plotinus is that he maybe not singlehandedly, but I think more than anyone else, killed off the variety and dissension among the philosophical schools of antiquity.

Soul puts the determination or forms or images of forms, into matter.

There's going to be this realm of Platonic forms and then there's going to be this single mind, the 'nous', which grasps them.

In fact Plotinus thought not only that soul in general is eternal so that you always have soul, but he thought that each person's soul is eternal.

If you think about for example, proportionality and beauty, things like that, these seem to be some kind of representations of a kind of unity.
