Mary Fanton Roberts in The Craftsman: Beside the stature of this book, the ordinary novel and biography are curiously dwarfed. You read it with a poignant interest and close it with wonder, reverence and gratitude. There is something strangely touching about words so candid, and a draught of philosophy that has been pressed from such wild and bitter-sweet fruit. The message it contains is one to sink deep, penetrating and enriching whatever receptive soul it touches. This man's words are incandescent. Many of us feel that he is breathing into a language, grown trite from hackneyed usage, the inspiration of a quickened life.
Ida Gilbert Myers in Washington Star: Courage backs this revelation. The gift of self-searching animates it. Honesty sustains it. And Mr. Comfort's rare power to seize and deliver his vision inspires it. It is a tremendous thing—the greatest thing that this writer has yet done.
George Soule in The Little Review: Here is a man's life laid absolutely bare. A direct, big thing, so simple that almost no one has done it before—this Mr. Comfort has dared. People who are made uncomfortable by intimate grasp of anything, to whom reserve is more important than truth—these will not read Midstream through, but others will emerge from the book with a sense of the absolute nobility of Mr. Comfort's frankness.
Edwin Markham in Hearst's Magazine: Will Levington Comfort, a novelist of distinction, has given us a book alive with human interest, with passionate sincerity, and with all the power of his despotism over words. He has been a wandering foot—familiar with many strands; he has known shame and sorrow and striving; he has won to serene heights. He tells it all without vaunt, relating his experience to the large meanings of life for all men, to the mystic currents behind life, out of which we come, to whose great deep we return.
