Spencer Tracy, in a true sense, was on a wavelength with humanity across the globe. He knew the predatory nature of man, but searched for the kindlier qualities they also have in common. In that search, he developed tolerance and great insights. Because he extolled the virtues that he found in all men, he himself flowered as a human being and became uninhibited and wholly integrated.
Spence was indeed a rare human being— a man for all peoples, all faiths, all seasons.
William O. Douglas [Associate Justice of the United States Supreme Court]
