Phronema

Phronema is a transliteration of the Greek word φρόνημα, which has the meanings of "mind", "spirit", "thought", "purpose", "will", and can have either a positive meaning ("high spirit", "resolution", "pride") or a bad sense ("presumption", "arrogance").
In the New Testament, the word is used four times in Saint Paul's Letter to the Romans: twice with "τῆς σαρκός" (of the flesh) and twice with "τοῦ πνεύματος" (of the spirit): "for the "mind" of the flesh [is] death, and the "mind" of the Spirit – life and peace; because the "mind" of the flesh [is] enmity to God ...and He who is searching the hearts hath known what [is] the "mind" of the Spirit" (Romans 8:6-7,27).
Eastern Orthodox theology.
The term "phronema" is used in Eastern Orthodox theology for one particular "mindset" or "outlook" – the "Orthodox mind". The attaining of "phronema" in this sense is a matter of practicing the correct faith ("orthodoxia") in the correct manner ("orthopraxis"). Attaining "phronema" is regarded as the first step toward "theosis", the state of "glorification". 
"Phronema" is also the name of the official annual review of St Andrew's Greek Orthodox Theological College, Sydney, Australia. It presents articles and book reviews from Orthodox and non-Orthodox on topics with central reference to theology, Church history and Orthodoxy.
Use by John Henry Newman.
The term was used by John Henry Newman in an article published in 1859 under the title "On Consulting the Faithful in Matters of Doctrine". He said that the "consensus" of the faithful is to be regarded as "a sort of instinct, or "phronēma", deep in the bosom of the mystical body of Christ".
Use by Ernst Haeckel.
The term was used by Ernst Haeckel in his book "The Wonders of Life" where (p. 342) the phronema is the name given to a part of the cortex, as “the real organ of mind”.
