I think from my still limited understanding of theology that the artical describes what I have seen in many other places both in the fathers and more modern texts about the development of passions (any not just pride). I will not comment on the references to the Ladder of divine assent as I have only recently go this and am only in the early stages of my first reading of it.
Personally I think the use of Jungian types is not reverent to the question at hand, since it is a product of modern science, not the science of the fathers which is what we use to understand sin. Jugian types are used in some forms of western Spirituality, mostly to give a reason of many types of worship, and in my opinion as an excuse why people will not accept that the Church in her wisdom can say one thing for all people. I cannot see how it can be in any way retentive to the life of an Orthodox Christian.
I have seen in some stories told by saints and some monastics as well as other writings that a too much concern for how you are seen by others can be a symptom of pride and inexperience in the Spiritual life. The peace labors some points too much and misses others that the fathers mention, in my opinion it is not a compleatly balanced peace and needs to be tempered with the other writings both modern and from the fathers.
