The research questions that motivate most quantitative studies in the health, social and behavioral sciences are not statistical but causal in nature. For example, what is the efficacy of a given drug in a given population? Whether data can prove an employer guilty of hiring discrimination? What fraction of past crimes could have been avoided by a given policy? What was the cause of death of a given individual, in a specific incident? These are causal questions because they require some knowledge of the data-generating process; they cannot be computed from the data alone.

Whatever doubts I had about internal happenings in Russia, I was quite clear in my mind about her foreign policy. This had been consistently one of peace and, unlike England and France, of fulfilling international obligations and supporting the cause of democracy abroad. The Soviet Union stood as the one real effective bulwark against Fascism in Europe and Asia. Without the Soviet Union what could be the state of Europe today? Fascist reaction would triumph everywhere and democracy and freedom would become dreams of a past age.

This example illustrates the differences in the effects which may be produced by research in pure or applied science. A research on the lines of applied science would doubtless have led to improvement and development of the older methods - the research in pure science has given us an entirely new and much more powerful method. In fact, research in applied science leads to reforms, research in pure science leads to revolutions, and revolutions, whether political or industrial, are exceedingly profitable things if you are on the winning side.

General Systems Theory is a name which has come into use to describe a level of theoretical model-building which lies somewhere between the highly generalized constructions of pure mathematics and the specific theories of the specialized disciplines. Mathematics attempts to organize highly general relationships into a coherent system, a system however which does not have any necessary connections with the "real" world around us. It studies all thinkable relationships abstracted from any concrete situation or body of empirical knowledge.

In view of the importance of philanthropy in our society, it is surprising that so little attention has been given to it by economic or social theorists. In economic theory, especially, the subject is almost completely ignored. This is not, I think, because economists regard mankind as basically selfish or even because economic man is supposed to act only in his self-interest; it is rather because economics has essentially grown up around the phenomenon of exchange and its theoretical structure rests heavily on this process.

Is it not possible that the chimpanzees are responding to some feeling like awe? A feeling generated by the mystery of water; water that seems alive, always rushing past yet never going, always the same yet ever different. Was it perhaps similar feelings of awe that gave rise to the first animistic religions, the worship of the elements and the mysteries of nature over which there was no control? Only when our prehistoric ancestors developed language would it have been possible to discuss such internal feelings and create a shared religion.
