Original thought, which does not reason from previous thoughts, Plotinus calls Intellect. So Intellect is a maker. But there is no process in its making, only the timeless activity of thinking the intelligible Forms that it is. Human souls have parts, and the highest part is still linked with Intellect 'there'. These future lives will reward and punish us, so keeping the moral balance in our necessarily imperfect but providentially ordered 'here'.
Soul is the lowest of Plotinus' three universal principles, or 'hypostases'.
It depends on Intellect, which in turn depends on the One, or Good. The One himself is 'beyond being', because attribution of being or any other predicate would make him more than One. Desire to touch him is the pang of being smitten by 'beauty above beauty'. The Oxford Companion to Philosophy 2. The Penguin Dictionary of Psychology 4.
