The very essence of political philosophy is the carving out of an ethical system - strictly, a subset of ethics dealing with political ethics. Ethics is the one rational discipline that demands the establishment of a rational set of value judgments; political ethics is that subset applying to matters of State.

The notion of ambiguity must not be confused with that of absurdity. To declare that existence is absurd is to deny that it can ever be given a meaning; to say that it is ambiguous is to assert that its meaning is never fixed, that it must be constantly won. Absurdity challenges every ethics; but also the finished rationalization of the real would leave no room for ethics; it is because man's condition is ambiguous that he seeks, through failure and outrageousness, to save his existence.
Existentialism does not offer to the reader the consolations of an abstract evasion: existentialism proposes no evasion. On the contrary, its ethics is experienced in the truth of life, and it then appears as the only proposition of salvation which one can address to men.
If the leading Negro classes cannot assume and bear the uplift of their own proletariat, they are doomed for all time. It is not a case of ethics; it is a plain case of necessity. The method by which this may be done is, first, for the American Negro to achieve a new economic solidarity.
