It seemed impossible either to go forward or to turn back. Years later, I encountered a sonnet by Sheldon Vanauken that precisely described my dilemma. Its concluding lines: Between the probable and proved there yawns A gap. Afraid to jump, we stand absurd, Then see behind us sink the ground and, worse, Our very standpoint crumbling. Desperate dawns Our only hope: to leap into the Word That opens up the shuttered universe. For a long time I stood trembling on the edge of this yawning gap. Finally, seeing no escape, I leapt. How can such beliefs be possible for a scientist? Aren't many claims of religion incompatible with the "Show me the data" attitude of someone devoted to the study of chemistry, physics, biology, and medicine? By opening the door of my mind to its spiritual possibilities, had I started a war of worldviews that would consume me, ultimately facing a take-noprisoners victory of one or the other?
