Unlike later Neo-Platonists, Plotinus says that our souls are always connected to the universal intellect and that we never really fall away.

Plotinus thought that the entire world has a single soul. He also thought that each animal and plant and of course human, has an individual soul.

Your soul existed before your birth, your soul will exist after your death.

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.

Just the way you might look at a painting and see the painting, and the painting is outside you, so this immaterial intellect would see the forms and behold them, as if they were standing before it. And Plotinus said that that can't be right because it falls prey to sceptical objections.

This is in a way the most important thing about soul is that it's a kind of principle which mediates between the universal intellect and the material world.

Once you're in a kind of revealed religious tradition, you wind up having to explain how the things said about God in the Bible or the Qur'an or whatever religious text you're dealing with, why these statements are true.
