Critique of Dialectical Reason
Jean-Paul Sartre
 Critique of Dialectical Reason is the product of a later stage in Sartre's thinking, during which he no longer identified Marxism with the Soviet Union or French Communism but came closer to identifying as a Marxist. It puts forward a revision of Existentialism, and an interpretation of Marxism as a contemporary philosophy par excellence, one that can be criticized only from a reactionary pre-Marxist standpoint. Sartre argues that while the free fusion of many human projects may possibly constitute a Communist society, there is no guarantee of this. Conscious human acts are not projections of freedom that produce human 'temporality', but movements toward 'totalization', their sense being co-determined by existing social conditions. People are thus neither absolutely free to determine the meaning of their acts nor slaves to the circumstances in which they find themselve. Social life does not consist only of individual acts rooted in freedom, since it is also a sedimentation of history by which we are limited and a fight with nature, which imposes further obstacles and causes social relationships to be dominated by scarcity. Every satisfaction of a need can cause antagonism and make it more difficult for people to accept each other as human beings. Scarcity deprives people of the ability to make particular choices and diminishes their humanity. Communism will restore the freedom of the individual and his ability to recognize the freedom of others.
