Context: During the past half century Negroes have migrated on a massive scale, transplanting millions from rural communities to crammed urban ghettoes. In their migration, as with all migrants, they carried with them the folkways of the countryside into an inhospitable city slum. The size of family that may have been appropriate and tolerable on a manually cultivated farm was carried over to the jammed streets of the ghetto. In all respects Negroes were atomized, neglected and discriminated against. Yet, the worst omission was the absence of institutions to acclimate them to their new environment. Margaret Sanger, who offered an important institutional remedy, was unfortunately ignored by social and political leaders in this period. In consequence, Negro folkways in family size persisted. The problem was compounded when unrestrained exploitation and discrimination accented the bewilderment of the newcomer, and high rates of illegitimacy and fragile family relationships resulted.

Interview with Rene Fulop-Miller (24 March 1923)
Context: I am a person who has never used violence himself. My present opinion is that people who have obtained the ballot should use it and solve their problems in that way. In the case of peoples who have not obtained the ballot, and who cannot control their states, I again find in my own mind a division of opinion, which is not logical, but purely a rough practical judgment. My own forefathers got their political freedom by violence; that is to say, they overthrew the British crown and made themselves a free Republic. Also by violence they put an end to the enslavement of the black race on this continent.

Context: One of my working assumptions which has been proven successful so often as seemingly to qualify it as a reliable tenet is that A problem adequately stated is a problem solved theoretically and immediately, and therefore subsequently to be solved, realistically. Others have probably stated the principle in many ways. The assumption is that the inevitability of a solution's realization is inherent in the interaction of human intellect and the constantly transformative evolution of physical universe. At first the, only subconsciously apprehended, approaching confluences of complex events make themselves known intuitively within the intellectual weather. Then comes a gradually awakening consciousness of the presence of new families of differentiating-out challenging concepts of every day prominence. It is with these randomly patterning families of separate concepts that evolution is about to deal integratively. As a now specific unitary problem it may be disposed of effectively when and if that unified problem becomes "adequately stated" and thereby comprehensibly solvable.
