The power of faith over the lack of it,--that is the vital seed from which, under the strong, sure treatment of Augustus Thomas, springs a drama of race and religion, of prejudice and sacrifice, of hate that would blight and love that can and will save and atone. This drama, the noblest and most intensely provocative of hard thinking that Boston has seen for many days, is called "As a Man Thinks". Into an apparently hopeless turmoil of sin and mental suffering which comes from the faithlessness of a husband and his suspicion of the faithlessness of his wife, into that very world which the modern "problem play" has bared so relentlessly, comes the calm, certain figure of a Jewish doctor, invincible because he possesses what those tortured spirits round him lack,--faith. Through the sheer force which it gives him, he instills it into them, and reconciles them. Another teaching is prominent: that true faith is something so deep and so compelling that it can be confined to no one sect or race. He who goes to this play with an unreasoning and instinctive aversion to a Jew, will find much material for sober reflection. "As a man thinketh in his heart, so is he," be he Jew or Gentile; and to think rightly is impossible without faith in God. This may sound like sermonizing, but if ever a sermon brought conviction to the heart of its hearer, this one preached by Mr. Thomas and interpreted in a masterly way by Mr. Mason and his excellent company, should touch the heart and stir the mind also.
