Every one agrees that man's acts are determined by something, and that, whether he acts orderly or not, there are sufficient grounds for his acting as he does act, if only these grounds can be discovered. In order to formulate such laws we must study man in action--his adjustments to the daily situations of life, and to the unusual situations which may confront him. When sufficiently worked out, the principles we obtain from such a study permit of two generalizations: (1) To predict human activity with reasonable certainty. It is sometimes asserted that we can never reach a point where such predictions can be made--that human activity is too variable; and determined by too many momentary conditions to permit us ever to reach such a goal. A little consideration shows that common-sense psychology is already, and has been since the social life of man began, making1 serviceable predictions. Every institution and custom we have depends upon it; for example, our savings banks, churches, and business. When it comes to the individual the facts are not different.
