It holds good also in human affairs: advantage is always accompanied by disadvantage; loss by gain; convenience by inconvenience; good by evil; rise by fall; prosperity by adversity; virtue by vice; beauty by deformity; pain by pleasure; youth by old age; life by death. 'A handsome young lady of quality,' a parable in Mahaparinirvana-sutra tells us, 'who carries with her an immense treasure is ever accompanied by her sister, an ugly woman in rags, who destroys everything within her reach. If we win the former, we must also get the latter.' As pessimists show intense dislike towards the latter and forget the former, so optimists admire the former so much that they are indifferent to the latter. 4. Life Consists in Conflict. Life consists in conflict. So long as man remains a social animal he cannot live in isolation. All individual hopes and aspirations depend on society. Society is reflected in the individual, and the individual in society. In spite of this, his inborn free will and love of liberty seek to break away from social ties. He is also a moral animal, and endowed with love and sympathy. He loves his fellow-beings, and would fain promote their welfare; but he must be engaged in constant struggle against them for existence. He sympathizes even with animals inferior to him, and heartily wishes to protect them; yet he is doomed to destroy their lives day and night. He has many a noble aspiration, and often soars aloft by the wings of imagination into the realm of the ideal; still his material desires drag him down to the earth. He lives on day by day to continue his life, but he is unfailingly approaching death at every moment. The more he secures new pleasure, spiritual or material, the more he incurs pain not yet experienced. One evil removed only gives place to another; one advantage gained soon proves itself a disadvantage. His very reason is the cause of his doubt and suspicion; his intellect, with which he wants to know everything, declares itself to be incapable of knowing anything in its real state; his finer sensibility, which is the sole source of finer pleasure, has to experience finer suffering. The more he asserts himself, the more he has to sacrifice himself. These conflictions probably led Kant to call life "a trial time, wherein most succumb, and in which even the best does not rejoice in his life." "Men betake themselves," says Fichte, "to the chase after felicity. . . . But as soon as they withdraw into themselves and ask themselves, 'Am I now happy?' the reply comes distinctly from the depth of their soul, 'Oh no; thou art still just as empty and destitute as before!' . . . They will in the future life just as vainly seek blessedness as they have sought it in the present life."
