Abstract
The two tractates forming the treatise of Plotinus, called rather misleadingly, to the modern mind, ‘On Providence’, have attracted attention mainly because of the remarkable stress laid in them on the doctrine of the Logos, which marks an interesting development of Plotinus' latest thought and brings the treatise into an apparently close relation to other systems with which the philosophy of Plotinus has little in common. I do not, however, in this article wish to discuss the Logos doctrine of these tractates, but rather to compare certain other aspects of the thought of the treatise with their probable sources in the work of earlier thinkers, and in particular to draw attention to a curious and unexpected parallelism of thought in one passage. I think that conclusions of some interest for the history of Greek thought in general can be drawn from such a comparison.
