As a non-inhibited response, force and brutality appear in the mentally sick. General paresis, cerebral arterio-selerosis, alcoholic psychoses present classical examples of the impatient brutal reaction, often in men hitherto patient and gentle. 2. Strategy or cunning appears as a second great method of obtaining the fulfillment of one's purposes. We all use strategy in the face of superior or equal power, just as we tend to use force confronted by inferiority. There is of course a legitimate use of cunning, but there is also an anti-social trend to it, quite evident in those who by nature or training are schemers. The strategist in love, war or business simulates what he does not feel, is not frank or sincere in his statements and believes firmly that the end justifies the means. He uses the indirect force of the lie, the slander, insinuation --he has no aversion to flattery and bribery--he uses spies and false witnesses. He is a specialist in the unexpected and seeks to lull suspicion and disarms watchfulness, waiting for the moment to strike. Sometimes he weaves so tangled a web that he falls into it himself, and one of the stock situations in humor, the novel and the stage is where the cunning schemer falls into the pit he has dug for others. In his highest aspect he is the diplomat; in his lowest he is the sneak. People who are weak or cowardly tend to the use of these methods, but also there is a group of the strong who hate direct force and rather like the subtler weapons. The strategist tends to be quite cynical, and his effect on his fellow men is to increase cynicism and pessimism. They who have suffered through the schemer grow to suspect their fellows under any guise. They become suspicious and hard, determined never to trust any one again. Indeed, practical wisdom to a large extent is the wisdom of strategy and is full of mottoes and proverbs inculcating non-generous ideals. When people have been "fooled" or misled, the most valuable of the social cementing qualities, faith in one's fellows, is weakened. Despite the disintegrating effect of unscrupulous shrewdness, it is common enough to hear men say of a successful votary of the art, "Well, I give him credit. He is a very clever fellow, and he has brought home the bacon." Success is so highly prized and admired that the means of obtaining it becomes secondary in the eyes of the majority. 3. The role of speech in the relationships of human beings is of course too great to be over-estimated. Speech becomes the prime weapon in swaying and molding the opinions and acts of others. It is the medium of the threat of force and the stratagem of cunning, but also it enters human life as the medium of persuasion and conviction. The speech ability, the capacity to use words in attaining purpose, shows as striking variations as any other capacity.
