George Santayana Quote

American life is a powerful solvent. As it stamps the immigrant, almost before he can speak English, with an unmistakable muscular tension, cheery self-confidence and habitual challenge in the voice and eyes, so it seems to neutralize every intellectual element, however tough and alien it may be, and to fuse it in the native good-will, complacency, thoughtlessness, and optimism.
