It should be understood that by starting with the consideration of matter as something already existent and mind as something which has yet to come into existence, science has arrived at the impassable "gap" in its explanation of human world experience. This gap will remain forever impassable because unless consciousness existed previously, the sense-stimuli might strike on the brain incessantly but they would never get any response. However, by science retracing its steps, dropping materialism, and starting with the mentalist line first, the gap vanishes and science can proceed to wonderful discoveries which will bring it into fraternal relation with religion and metaphysics. It will then understand that all life becomes a play of consciousness.
