We all know there are regions of the human spirit untrammelled by the world of physics. In the mystic sense of the creation around us, in the expression of art, in the yearning toward God, the soul grows upward and finds the fulfilment of something implanted in its nature. The sanction for this development is within us, a striving born with our consciousness or an Inner Light proceeding from a greater power than ours. Science can scarcely question this sanction, for the pursuit of science springs from a striving which the mind is impelled to follow, a questioning that will not be suppressed. Whether in the intellectual pursuits of science or in the mystical pursuits of the spirit, the light beckons ahead. The purpose surging in our nature responds.
