The evils and burdens of such a temperament are half removed when a man once knows that he has it and recognizes it for a disease, and when he does not trust himself to speak and act in those bitter hours as if there were any truth in what he thinks and feels and sees. He who has not attained to this wisdom overwhelms his friends and his family with the waters of bitterness; he stings with unjust accusations, and makes his fireside dreadful with fancies which are real to him, but false as the ravings of fever. A sensible person, thus diseased, who has found out what ails him, will shut his mouth resolutely, not to give utterance to the dark thoughts that infest his soul. A lady of great brilliancy and wit, who was subject to these periods, once said to me, “My dear sir, there are times when I know I am possessed of the Devil, and then I never let myself speak.” And so this wise woman carried her burden about with her in a determined, cheerful reticence, leaving always the impression of a cheery, kindly temper, when, if she had spoken out a tithe of what she thought and felt in her morbid hours, she would have driven all her friends from her, and made others as miserable as she was herself. She was a sunbeam, a life-giving presence in every family, by the power of self-knowledge and self-control. Such victories as this are the victories of real saints. But if the victim of these glooms is once tempted to lift their heavy load by the use of _any stimulus whatever_, he or she is a lost man or woman. It is from this sad class more than any other that the vast army of drunkards and opium-eaters is recruited. Dr. Johnson, one of the most brilliant examples of the hypochondriac temperament which literature affords, has expressed a characteristic of the race, in what he says of himself, that he could “_practise_ ABSTINENCE _but not_ TEMPERANCE.” Hypochondriacs who begin to rely on stimulus, almost without exception find this to be true. They cannot, they will not be moderate. Whatever stimulant they take for relief will create an uncontrollable appetite, a burning passion. The temperament itself lies in the direction of insanity. It needs the most healthful, careful, even regimen and management to keep it within the bounds of soundness; but the introduction of stimulants deepens its gloom with the shadows of utter despair. All parents, in the education of their children, should look out for and understand the signs of this temperament. It appears in early childhood; and a child inclined to fits of depression should be marked as a subject of the most thoughtful, painstaking physical and moral training. All over-excitement and stimulus should be carefully avoided, whether in the way of study, amusement, or diet. Judicious education may do much to mitigate the unavoidable pains and penalties of this most undesirable inheritance.
