28 Th e full "Second Th esis on Feuerbach" reads: "Th e question whether objective truth can be attributed to human thinking is not a question of theory but is a practical question. Man must prove the truth— i.e., the reality and power, the thissidedness of his thinking in practice. Th e dispute over the reality and nonreality of thinking that is isolated from practice is a purely scholastic question." See Marx and Engels ( 1969, vol. 1, 13– 15).
