You conclude:
...The certainty of Gnosis is a form of fundamentalism in my view, and we are in an age where all forms of fundamentalism are being crushed by the weight of an intensified rationalism.
This simply affirms that you are among those who, as I said have never "experienced the transcendental revelation that the whole cosmos ("Kosmos') is One Intelligent Being."
Gnosis is not "belief" in God. It is the direct experience of the "Ultimate Reality" which is the pretended subject of this forum but "ultimately" beyond the reach of reason/logic alone.
You are the "fundamentalist" here as in "materialist flatlander" in denial of the transcendental aspect of consciousness altogether...
in denial of the whole branch of epistemology (a-priori as contrasted with a-posteriori) addressing knowledge through Identity with this "Ultimate Reality." This is what gnosis actually is. You are not only clueless but determined to stay that way. This is true materialistic fundamentalism.
