The end of Part One found Merton at Columbia (1937–38): Gilson’s The Spirit of Mediaeval Philosophy gave him the idea of God as aseitas — being that exists of itself; Huxley’s Ends and Means led him to mysticism and asceticism; the Hindu monk Bramachari advised him to read Augustine’s Confessions and The Imitation of Christ; and Blake, the subject of his thesis, taught him that art without faith is a dead end. So the second part begins with a theoretical summary of what had gathered in him — and then tells how it turned out: reading about Hopkins, the sentence “what are you waiting for?”, the walk to Corpus Christi to see Fr Ford, and baptism on 16 November 1938.
Context added from other chapters of the book — these details are not in the opening of the chapter itself.
