Abstract
There is a long tradition in the philosophy of the social sciences that emphasizes the meaningfulness of human action. This tradition doubts or even negates the possibility of causal explanations of human action precisely on the basis that human actions have meaning. This paper provides an argument in favour of methodological naturalism in the social sciences. It grants the main argument of the Interpretivists, i.e. that human actions are meaningful, but it shows how a transformation of a “nexus of meaning” into a “causal nexus” can take place, proposing the “successful transformation argument”. Based on previous work presented in my Naturalistic Hermeneutics, Cambridge University Press, 2005 the paper discusses four approaches that describe the “nexus of meaning” connected with a human action based on the motives, the intentions, the reasons, and the rationality of the action respectively. From the standpoint of eachapproach a causal nexus can arise, namely, if the respective motives, intentions, reasons, or the human rationality that are manifest in the different nexuses of meaning exhibit certain invariances. These approaches can be formulated as theories, which explain human action every time that the nexuses of meaning – described with the diverse conceptual apparatuses – can be transformed into causal nexuses. It is shown that explanations based on motives, intentions, reasons, or rationality are possible, as are explanations of human action based on, at least in principle, an unlimited number of other theories.
