He never invested his whole moral capital in a man, a book, or a cause, but treasured up wisdom wherever it could be picked up, always with scrupulous acknowledgment … His eclecticism saving him from the cycle of hope-disillusion-despair, his highest effectiveness was as a skirmisher in the daily battle for light and justice, as a critic of new doctrine and a refurbisher of old, as a voice of warning and encouragement. That his action has not been in vain, we can measure by how little Shaw's iconoclasm stirs our blood; we no longer remember what he destroyed that was blocking our view.
