What is the main argument presented by New-Fist in response to the critics of his educational philosophy?

Here is the rewritten text from the image: 10 PART I: CONTEXT OF THE CURRICULUM Great Mystery never intended to have done; he is also a damned fool for trying to change human nature.' Whereupon approximately half of these critics took up the solemn chant, 'If you oppose the will of the Great Mystery, you must die,' and the remainder sang derisively in unison, 'You can't change human nature.' Being an educational statesman as well as an educational administrator and theorist, New-Fist replied politely to both arguments. To the more theologically minded, he said that, as a matter of fact, the Great Mystery had ordered this new work done, that he even did the work himself by causing children to want to learn, that children could not learn by themselves without divine aid, that they could not learn at all except through the power of the Great Mystery, and that nobody could really understand the will of the Great Mystery concerning fish, horses, and saber-tooth tigers unless he had been well grounded in the three fundamental subjects of the New-Fist school. To the human-nature-cannot-be-changed shouters, New-Fist pointed out the fact that paleolithic culture had attained its high level by changes in human nature and that it seemed almost unpatriotic to deny the very process which had made the community great. 'I know you, my fellow tribesmen,' the pioneer educator ended his argument gravely, 'I know you as humble and devoted servants of the Great Mystery. I know that you would not for one moment consciously oppose yourselves to his will. I know you as intelligent and loyal citizens of this great cave-realm, and I know that your pure and noble patriotism will not permit you to do anything which will block the development of that most cave-realmish of all our institutions — the paleolithic educational system. Now that you understand the true nature and purpose of this institution, I am serenely confident that there are no reasonable lengths to which you will not go in its defense and its support.' By this appeal the forces of conservatism were won over to the side of the new school, and in due time everybody who was anybody in the community knew that the heart of good education lay in the three subjects of fish-grabbing, horse-clubbing, and tiger-scaring. New-Fist and his contemporaries grew old and were gathered by the Great Mystery to the Land of the Sunset far down the creek. Other men followed their educational ways more and more, until at last all the children of the tribe were practiced systematically in the three fundamentals. Thus the tribe prospered and was That's 2 down. 3 left today — send the next one.
