Book excerpt: 'Support-Bargaining, Economics and Society links support-bargaining to Darwin's theory of natural selection and traces the implications of support-bargaining and money-bargaining across society. It provides a wholly different account of the functioning of human societies from anything that has gone before. Social scientists, ever since there have been such people, have missed the crucial human characteristic - the propensity to seek support - that has given rise to group formation and the myriad activities that are feasible in groups.
