Philosophical theories summarized here include regularity and necessity theories from Hume to the present; manipulability theory; the theory of powerful particulars; causation as connected changes within a denned state of affairs; departures from "normal" events or from some standard for comparison; causation as a transfer of something between objects; and causal propagation and production. Issues found in this literature and of relevance for psychology include whether actual causal relations can be perceived or known; what sorts of things people believe can be causes; different levels of causal analysis; the distinction between the causal relation itself and cues to causal relations; causal frames or fields; internal and external causes; and understanding of causation in different realms of the world, such as the natural and artificial realms. A full theory of causal inference by laypeople should address all of these issues.The main purpose of this article is to survey philosophical theories of causation in a manner intended to be suitable for psychologists interested in causation. The article has two sections: The first presents brief summaries of philosophical theories of causation from Aristotle to the present. In the second, issues found in the philosophical literature are used to suggest new approaches to the study of causation in psychology.
Philosophical Theories of CausationSeveral psychologists have written about selected philosophical theories of causation (Cook & Campbell, 1979;Einhorn & Hogarth, 1986;Hastie, 1983;Shaver, 1985;Shultz, 1982), but a comprehensive survey of the philosophical literature has, as yet, not been published in psychology. Most psychological research and theory on causal inference and attribution has taken some philosophical notion as its point of departure, so a wide survey of recent philosophy is likely to be of value as a source of new ideas and hypotheses about causal inference and attribution in psychology. It is not, however, the purpose of this article to evaluate the philosophical merits and weaknesses of theories, nor to provide a comprehensive review of the philosophical literature with its many debates between proponents of different views. Rather, from the point of view of use in psychology, my aim is to give summary sketches of the most important points of each theory. Although intended to communicate the essential character of each theory, these sketches are necessarily oversimplified; readers wishing a more complete exposition should consult the original sources. Mostly I have refrained from classifying different authors together, but in some cases I have adopted the groupings used by Beauchamp (1974), without meaning to imply that there are no differences between the views of different authors grouped together.
