 Turn now to the accounts of the individual-level microfoundations. These are specifications of the underlying individual-level mechanisms understood as causal chains of events, that occur at the level of individuals, and that link some cause in the form of a social phenomenon to its effect in the form of another social phenomenon. Very often, accounts of this sort are taken to consist of three parts. Part I lays out how a social phenomenon resulted in individuals forming various beliefs and desires, and having certain opportunities. Part II states how these beliefs, desires, and opportunities gave rise to individuals acting and interacting in a certain manner. Part III outlines how these actions and interactions, intentionally or unintentionally, brought about a certain social phenomenon. As an illustration of an account along these lines, consider the example of the purely holist explanation that “the protestant ethic caused the rise of capitalism in the West”. A very rough three-part account of the underlying individual-level mechanisms might go as follows. The protestant ethic compelled individuals to adopt certain values. These, in turn, induced them to engage in certain new forms of economic behavior. Those, finally, caused the rise of capitalism in the West. Frequently, Coleman’s well-known boat model is used to depict how purely holist explanations must include such three-part accounts of the underlying individual-level mechanisms (Coleman 1986, 1990). The model uses a boat form to illustrate the move from one social phenomenon down to individual-level events and up again to another social phenomenon.
