Herbert Marcuse Quote

Dialectical thought understands the critical tension between is and ought first as an ontological condition, pertaining to the structure of Being itself. However, the recognition of this state of Being — its theory — intends from the beginning a concrete practice. Seen in the light of a truth which appears in them falsified or denied, the given facts themselves appear false and negative.
