The next step was taken by the philosopher Yang Hsiung (_Sheeyoong_), 53 B.C. to A.D. 18. He started a theory which occupies a middle place between the last two theories discussed above, teaching that the nature of man at birth is neither wholly good nor wholly evil, but a mixture of both, and that development in either direction depends altogether on environment. A compromise in matters of faith is not nearly so picturesque as an extreme, and Yang's attempted solution has attracted but scant attention, though always mentioned with respect. The same may also be said of another attempt to smooth obvious difficulties in the way of accepting either of the two extremes or the middle course proposed by Yang Hsiung. The famous Han Yu, to be mentioned again shortly, was a pillar and prop of Confucianism. He flourished between A.D. 768 and 824, and performed such lasting services in what was to him the cause of truth, that his tablet has been placed in the Confucian temple, an honour reserved only for those whose orthodoxy is beyond suspicion. Yet he ventured upon an attempt to modify this important dogma, taking care all the time to appear as if he were criticizing Mencius rather than Confucius, on whom, of course, the real responsibility rests. He declared, solely upon his own authority, that the nature of man is not uniform but divided into three grades--namely, highest, middle, and lowest. Thus, natures of the highest grade are good, wholly good, and nothing but good; natures of the lowest grade are evil, wholly evil, and nothing but evil; while natures of the middle grade may, under right direction, rise to the highest grade, or, under wrong direction, sink to the lowest. Another question, much debated in the age of Mencius, arose out of the rival statements of two almost contemporary philosophers, Mo Ti (_Maw Tee_) and Yang Chu. The former taught a system of mutual and consequently universal love as a cure for all the ills arising from misgovernment and want of social harmony. He pointed out, with much truth, that if the feudal states would leave one another alone, families cease to quarrel, and thieves cease to steal, while sovereign and subject lived on terms of benevolence and loyalty, and fathers and sons on terms of kindness and filial piety--then indeed the empire would be well governed. But beyond suggesting the influence of teachers in the prohibition of hatred and the encouragement of mutual love, our philosopher does little or nothing to aid us in reaching such a desirable consummation.
