W.e.b. Du Bois said this quote

The worlds within and without the Veil of Color are changing, and changing rapidly, but not at the same rate, not in the same way; and this must produce a peculiar wrenching of the soul, a peculiar sense of doubt and bewilderment. Such a double life, with double thoughts, double duties, and double social classes, must give rise to double words and double ideals, and tempt the mind to pretence or revolt, to hypocrisy or radicalism.
