Famous quotes containing the words logical and/or assertion:

    Nature’s law says that the strong must prevent the weak from living, but only in a newspaper article or textbook can this be packaged into a comprehensible thought. In the soup of everyday life, in the mixture of minutia from which human relations are woven, it is not a law. It is a logical incongruity when both strong and weak fall victim to their mutual relations, unconsciously subservient to some unknown guiding power that stands outside of life, irrelevant to man.
    Anton Pavlovich Chekhov (1860–1904)

    Emancipation should make it possible for woman to be human in the truest sense. Everything within her that craves assertion and activity should reach its fullest expression; all artificial barriers should be broken, and the road towards greater freedom cleared of every trace of centuries of submission and slavery.
    Emma Goldman (1869–1940)
