Duehring insisted that his philosophy was a realist philosophy and Engels serious arguments, apart from the elaborate ridicule with which he covers his opponent and which is by no means a recommendation to the book, is directed to show that it is not realist, that it depends upon certain preconceived notions. Of these notions some are axiomatic, as Duehring claims, that is they are propositions which are self evident to Herr Duehring but which will not stand investigation. Others again are untrue and are preconceptions so far as they are out of harmony with established facts.

Much of Engels work is out of date judged by recent biological and other discoveries, but the essential argument respecting the interdependence of all departments of knowledge, and the impossibility of making rigid classifications holds good to-day in a wider sense than when Engels wrote. Scientific truths which have been considered absolute, theories which have produced approximately correct results, have all been discredited. The dogmas of science against which the dogmatic ecclesiastics have directed their scornful contempt have shared the same fate as the ecclesiastical dogmas. Nothing remains certain save the certainty of change. There are no ultimates. Even the atom is suspect and the claims of the elements to be elementary are rejected wholesale with something as closely resembling scorn as the scientist is ever able to attain. A scientific writer has recently said "What is undeniable is that the Daltonian atom has within a century of its acceptance as a fundamental reality suffered disruption. Its proper place in nature is not that formerly assigned to it. No longer 'in seipso totus, teres, atque rotundus' its reputation for inviolability and indestructibility is gone for
