This does not mean that we should be always self-consciously studying ourselves, ready to nip the pernicious idea in the bud; nor yet that we should adopt the ostrich's policy of sticking our heads in the sand and declaring that disease and evil have no real existence. The one leads to egotism and the other to callousness. Duty sometimes requires us to give our attention to things in themselves evil and depressing. The demands of friendship and human sympathy are imperious, and we cannot ignore them without moral loss. But there is a positive and a negative way of approaching such subjects. Sympathy is too often regarded as a passive process by which we allow ourselves to be infected by the gloom, the weakness, the mental ill-health of other people. This is sympathy perverted. If a friend is suffering from small-pox or scarlet fever you do not seek to prove your sympathy by infecting yourself with his disease. You would recognize this to be a crime against the community. Yet many people submit themselves to infection by unhealthy ideas as if it were an act of charity--part of their duty towards their neighbours. In the same way people deliver their minds to harrowing stories of famine and pestilence, as if the mental depression thus produced were of some value to the far-away victims. This is obviously false--the only result is to cause gloom and ill-health in the reader and so make him a burden to his family. That such disasters should be known is beyond question, but we should react to them in the manner indicated in the last chapter. We should replace the blank recognition of the evil by the quest of the means best suited to overcome it; then we can look forward to an inspiring end and place the powers of our will in the service of its attainment. Oh, human soul, as long as thou canst so, Set up a mark of everlasting light Above the heaving senses' ebb and flow ... Not with lost toil thou labourest through the night, Thou mak'st the heaven thou hop'st indeed thy home. Autosuggestion, far from producing callousness, dictates the method and supplies the means by which the truest sympathy can be practised. In every case our aim must be to remove the suffering as soon as possible, and this is facilitated by refusing acceptation to the bad ideas and maintaining our own mental and moral balance.
