Since it is in part a judgment of character in the most of us, it tends to grow less prominent as we grow older. The young child is either very trusting or entirely suspicious, and when his suspicions are overcome by acquaintance and simple bribes, he yields his fortunes to any one. (It is a pleasant fiction that children and dogs know whom to trust, by an intuition.) But as life proceeds, the most of us find that our judgment of character is poor, and we hesitate to pin anything momentous on it. Only where passion blinds us, as in sex love, or when our self-love and lust for quick gain[1] or hate has been aroused do we lose the caution that is the antithesis of trust. The expert in human relations is he who can overcome distrust; the genius in human relations is he who inspires trust. For the psychopathologist an enormous interest centers in a group of people whom we may call paranoic. In his mildest form the paranoic is that very common "misunderstood" person who distrusts the attitude and actions of his neighbors, who believes himself to be injured purposely by every unintentional slight, or rather who finds insult and injury where others see only forgetfulness or inattention. Of an inordinate and growing ego, the paranoic of a pathological trend develops the idea or delusion of persecution. From the feeling that everything and every one is against him, he builds up, when some major purpose becomes balked, a specific belief that so and so or this or "that group is after me." "They are trying to injure or kill me" because they are jealous or have some antagonistic purpose. Here we find the half-baked inventor, whose "inventions" have been turned down for the very good reason that they are of no value, and who concludes [1] All the great swindlers show how the lust for gain plus the wiles of the swindler overcome the caution and suspicion of the "hard-headed," The Ponzi case is the latest contribution to the subject. that some big corporations are in league with the Patent Office to prevent him from competing with them; here we have the "would-be" artist or singer or writer whose efforts are not appreciated, largely because they are foolish, but who believes that the really successful (and he often names them) hate and fear him, or that the Catholics are after him, or perhaps the Jews or the Masons. In its extreme form the paranoic is rare just as is the extremely trusting person of saintly type. But in minor form every group and every institution has its paranoic, hostile, suspicious, "touchy," quick to believe something is being put over on him and quick to attribute his failure to others. In that last is a cardinal point in the compass of character. Some attribute their failure to others, and some in their self-analysis find the root of their difficulties and failures in themselves.
