The most fundamental form of integrative power is the power of love. - Kenneth E. Boulding

In calling society an ecological system we are not merely using an analogy; society is an example of the general concept of an "ecosystem" that is, an ecological system of which biological systems--forests, fields, swamps--are other examples.

Economic progress... means the discovery and application of better ways of doing things to satisfy our wants. The piping of water to a household that previously dragged it from a well, the growing of two blades of grass where one grew before, the development of a power loom that enables one man to weave ten times as much as he could before, the use of steam power and electric power instead of horse or human power — all these things clearly represent economic progress.

The word 'policy' generally refers to the principles that govern action directed towards given ends. Any study of policy therefore should concern itself with three things — what we want (the ends), how we get it (the means), and who are 'we,' that is, what is the nature of the organization or group concerned. Science is concerned with means rather than with ends. The study of "what we want" (objectives) extends beyond the boundaries of the social sciences into the field of ethics. It is not the business of the social sciences to evaluate the ultimate ends of human activity. The social sciences, therefore, cannot give a final answer to the question whether any given policy is right. The social scientist can study what people say they want, what they think they want and may even infer from their behaviour what they really want, but it is not the business of science to say whether people want right things.
