In the light of this great principle Thyrsis had to revise all his previous knowledge; he had to cast out tons of rubbish from the chambers of his mind, and start his thinking life all over again. Just as, in early days, he had exchanged miracles and folk-tales for facts of natural science; so now he saw political institutions and social codes, literary and artistic canons, and ethical and philosophical systems, no longer as things valid and excellent, having relationship to truth--but simply as intrenchments and fortifications in the class-war, as devices which some men had used to deceive and plunder some other men. What a light it threw upon philosophy, for instance, to perceive it, not as a search for truth, but as a search for justification upon the part of ruling classes, and for a basis of attack upon the part of subject-classes! So, for instance, on the one side one found Rousseau, and on the other Herbert Spencer. Thyrsis had read Spencer, and had cordially disliked him for his dogmatism and his callousness; but now he read Kropotkin’s “Mutual Aid as a Factor in Evolution”, and came to a realization of how the whole science of biology had been distorted to suit the convenience of the British ruling-classes. _Laissez-faire_ and the Manchester school had taught him that “each for himself and the devil take the hindmost” was the universal law of life; and he had accepted it, because there seemed nothing else that he could do. But now, in a sudden flash, he came to see that the law of life was exactly the opposite; everywhere throughout nature that which survived was not ruthless egotism, but co-operative intelligence. The solitary and predatory animals were now almost entirely extinct; and even before the advent of man with his social brain, it had been the herbivorous and gregarious animals which had become most numerous. When it came to man, was it not perfectly obvious that the races which had made civilization were those which had developed the nobler virtues, such as honor and loyalty and patriotism? And now it was proposed to trample them into the mire of “business”; to abandon the race to a glorified debauch of greed! And this travesty of science was taught in ten thousand schools and colleges throughout America--and all because certain British gentlemen had wished to work their cotton-operatives fourteen hours a day, and certain others had wished to keep land which their ancestors had seized in the days of William the Conqueror! Shortly after this Thyrsis came upon Edmond Kelly’s great work, “Government, or Human Evolution”; and so he realized that Herbert Spencer’s social philosophy had at last been cleared out of the pathway of humanity. And this was a great relief to him--it was one more back-breaking task that he did not have to contemplate!
