Plotinus (c. 204/5- 270) was preoccupied with the question if what is called in philosophy ‘individuals’ exists; he connects the existence of these metaphysical ‘entities’ to that of ‘particulars’. He provides an account of sensible particulars which trace the individual nature of each distinct being (especially that of the individual human being) back to the causal power of the First Principle of soul and logos.
As one can see, Plotinus regards the nature of each individual as dependent on incorporeal sources. He does not provide in the end a definite conclusion to the issue whether there are any ideas of particulars individual. But will affirm that each individual is capable to ascend to the Intellect.
