ABSTRACT
The quantitative approach, though it may seem superficial in many respects, has the advantage over more traditional methods of social enquiry in that it lacks political or national bias. One of the causes of mental unrest in the world at the present time is the growing awareness among members of the human race of the vast extent of their own population. Thus is seems appropriate to pay attention to the reaction of crowds which are especially connected with or determined by the numbers of people they contain.
