"Then would Philo of Alexandria be Gnostic in this definition Knowledge of
God, or Wisdom."
Yes, but pre-Christian in the sense that there are definite similarities in the way the Pleroma (Logos) and Wisdom are put together. As you point out.....
" It (Logos) has many meanings such as word, speech, statement, discourse, refutation, ratio, account, explanation, reason. But the meanings which have philosophical and religious implications are basically two: as an inward thought or reason, an intuitive conception, and as an outward expression of thought in speech."
The difference it seems to me is the connection of the soul, and the bonding of the soul to Sophia, ( the 'Logos.') I do not know if, or how, Philo made the development of the soul as a prerequisite to Gnosis. Others on this list will know.
"Philo believed that man's final goal and ultimate bliss is in the "knowledge
of the true and living God;"
This is pretty much the same concept as what the 'core texts' are saying, but the nature of "God' is key to understanding how the connection is made between the perception of God, and the (soul) as to man's relationship to that entity.
One reason I contend the soul is, form, perception, consciousness, knowledge and action, is that these concepts can be seen as what might actually bond with "Sophia." I have pointed out these elements are named in Acts of Thomas, and other Eastern Christian works with ideas of the soul. The Apocryphon of John also suggests these elements as important to Gnosis.
Clement sees all Philosophy as having some truth to (Christian) Gnosis, but clarifies their are differences in the fundamental concepts between what he sees as the true "Knowledge." The Gospel of Phillip, states, "Since Christ came, the world has been created, the cities adorned, the dead carried out. When we were Hebrews, we were orphans and had only our mother, but when we became Christians, we had both father and mother."
