Fox offered us a different perspective on the "divine dark" which Eckhart and pseudo-Dionysius the Areopagite extol; he viewed it as the experience of desolation, of abandonment. I'm not so sure about this. Pseudo-Dionysius describes the dark as:
the ultimate summit of your mystical knowledge, most incomprehensible, most luminous and most exalted, where the pure, absolute and immutable mysteries of theology are veiled in the dazzling obscurity of the secret Silence, outshining all brilliance with the intensity of their Darkness, and surcharging our blinded intellects with the utterly impalpable and invisible fairness of glories surpassing all beauty.This is not a transient stage of despair, or finding God in the experience of desolation, as well as in consolation, but the ultimate stage, for Dionysius (and I think for Eckhart) of mystical union. (This very aspect of their thought is one reason for Inge's discomfort with both Dionysius and Eckhart).
To be fair, Fox used Eckhart's distinction between God (the Mover) and the Godhead (the Wisdom of God--which he informed was a mistranslation of the Gottheit, more properly translated as the "Godness"). In Eckhart, the Godhead is at points equated with the Divine Dark; for Fox, he stressed Wisdom as traditionally feminine, as restoring the gender balance our patriarchal society denies the Divine. (Actually, Eckhart's disciple Henry Suso, the "Servitor of the Divine Wisdom," whom he saw as a Lady whose knight he was, also drew this concept from Eckhart).
Finally, in place of the traditional three-step mystical progression, Fox postulates a four step path, described by him as "The Via Positiva (joy, delight and awe); the Via Negativa (darkness, silence, suffering, letting go and letting be); the Via Creativa (creativity); and the Via Transformativa (justice, compassion, interdependence). One interesting distinction: Fox's four-fold path emphasizes modes of being leading to action, the traditional path--pugation, illumination, and union--describes a furthering of the soul's union with God. As summarized by Inge, the first step--purgation--includes what Fox describes as his fourth step, duty to our fellow human beings and creation at large. What for Fox is the culmination is for Inge the beginning--the sine qua non.
