One of the major areas of criminology is to look for an adequate, comprehensive and holistic explanation of the causation of crime. Attempts have been made by many sociologists and Criminologists to suggest theoretical explanations for this purpose. Some have emphasized on biological factors in human being, some on psychological factors, some on social factors and some on other specific factors. But, none of these theories provide an adequate, comprehensive and holistic explanation of the causation of crime. The authors of the paper have tried to identify the limitations of the existing theories and finally suggested an alternative explanation which emphasizes all the relevant aspects of human behaviour and action including 'human perception' of the situations in which crime takes place.
