Since the beginnings of psychiatry in the early 19th century, it has been
recognized that there are persons whose persisting antisocial behavior can not
be understood in terms of mental disorder or neurotic motivations. The father of
French psychiatry, Phillipe Pinel, noted that some people seem to behave crazily
without actually being crazy. The German systematisist, like Robert Koch, first
coined the term "psychopathic" to describe such phenomenon now known
as personality disorders. Webster defines antisocial as "hostile or harmful
to organized society being marked by behavior sharply deviating from the social
norm." The diagnostic criteria for antisocial personality are as stands:
there us a pervasive pattern of disregard for and violation of the rights of
others occurring since the age of fifteen years. As indicated by three or more
of the following: 1. Failure to conform to social norms with respect to lawful
behaviors as indicated by repeatedly performing acts that are grounds for
arrest. 2. Deceitfulness, as indicated by repeated lying, uses of aliases, or
conning others for personal profit or pleasure. 3. Impulsivity or failure to
plan ahead. 4. Irrational ability and aggressiveness, as indicated by repeated
physical fights or assaults. 5. Reckless disregard for safety for self or
others. 6. Consistent irresponsibility as indicated by repeated failure to
sustain constant work behavior or honor financial obligations. 7. Lack of
remorse, as indicated by being indifferent to or rationalizing having hurt,
mistreated, or stolen from another.
