Philoxenes marks an absolute rupture between the intellectual vision of truth, which he sees as participating in the spiritual world of self-sufficiency, and the sensible world of untruth, to which human imagination and sensation are incorrigibly bound. Philoxenes writes in his Letter to Patricius,

Once the intellect has contemplated truth in its own region it may no longer express this contemplation in any lower region, and even if it wished it could not do so since it transcends all bodily sensations…. What it sees and hears within itself is experienced spiritually in the region of the Spirit alone.1
