From “The Discipline of Inspiration: The Mysterious Encounter with God at the Heart of Creativity” by Carey Wallace
At some future point, we may produce far more accurate maps of the mind, and even decode the meaning of each tiny charge that leaps from synapse to synapse. But because our minds are susceptible to things beyond them, we will never be able to definitively establish what stimuli cause our mind’s responses: an event in the visible world, a change in the weather of our own thoughts – so some signal that operates in a range currently outside measurable perception: what poets call muse, and prophets call God.
Even when each neuron is mapped, every chemical bottled, all dreams photographed, it will never be possible to prove that the unmeasurable presence of God is the fundamental ingredient in all art – just as it will never be possible to prove that it is not.
