Ibsen goes very far in his critique of bourgeois society, but he retains science as a measure of truth. Levi Strauss has made us realize that Western thought is not the lonely peak of human achievement it was once thought to be, but he and his followers exclude science from their relativization of ideologies. Marx and Engels were convinced that science would aid the workers in their quest for mental and social liberation.
