“Citing 13th-century Persian poet and philosopher Rumi‘s famous line — “the eye of the heart, which is seventy-fold and of which these two sensible eyes are only the gleaners” — Schumacher revisits the notion of perceiving with something other than the intellect:
The power of “the Eye of the Heart,” which produces insight, is vastly superior to the power of thought, which produces opinions.
This is the process of gaining adaequatio, of developing the instrument capable of seeing and thus understanding the truth that does not merely inform the mind but liberates the soul.
Ideas produce insight and understanding, and the world of ideas lies within us. The truth of ideas cannot be seen by the senses but only by that special instrument sometimes referred to as “the Eye of the Heart,” which, in a mysterious way, has the power of recognizing truth when confronted with it.”
