Neoplatonism
Neoplatonist philosophers such as Plotinus (204/5–270 AD) used the term "Logos" in ways that drew on Plato and the Stoics, but the term Logos was interpreted in different ways throughout Neoplatonism, and similarities to Philo's concept of Logos appear to be accidental. The Logos was a key element in the meditations of Plotinus regarded as the first Neoplatonist. Plotinus referred back to Heraclitus and as far back as Thales in interpreting Logos as the principle of meditation, existing as the interrelationship between the Hypostases (The 'One', 'Spirit' (nous) and 'Soul').
Plotinus used a trinity concept that consisted of "The One", the "Spirit" and "Soul". The comparison with the Christian Trinity is inescapable, but for Plotinus these were not equal and "The One" was at the highest level, with the "Soul" at the lowest. For Plotinus, the relationship between the three elements of his trinity is conducted by the outpouring of Logos from the higher principle, and eros (loving) upward from the lower principle. Plotinus relied heavily on the concept of Logos, but no explicit references to Christian thought can be found in his works, although there are significant traces of them in his doctrine. Plotinus specifically avoided using the term Logos to refer to the second person of his trinity. However, Plotinus influenced Victorinus who then influenced Augustine of Hippo. Centuries later, Carl Jung acknowledged the influence of Plotinus in his writings.
Victorinus differentiated between the Logos interior to God and the Logos related to the world by creation and salvation.
Augustine of Hippo, often seen as the father of medieval philosophy, was also greatly influenced by Plato and is famous for his re-interpretation of Aristotle and Plato in the light of early Christian thought. A young Augustine experimented with, but failed to achieve ecstasy using the meditations of Plotinus. In his Confessions Augustine described Logos as the Divine Eternal Word, by which he, in part, was able to motivate the early Christian thought throughout the Greek-influenced world (of which the Latin speaking West was a part) Augustine's Logos had taken body in Christ, the man in whom the logos (i.e. veritas or sapientia) was present as in no other man.
