ArgumentThis paper argues that Samuel Clarke's account of agent causation (i) provides a philosophical basis for moderate voluntarism, and (ii) both leads to and benefits from the acceptance of partial occasionalism as a model of causation for material beings. Clarke's account of agent causation entails that for an agent to be properly called an agent (i.e. causally efficacious), it is essential that the agent is free to choose whether to act or not. This freedom is compatible with the existence of (...) conceptually necessary connections. Hence, Clarke can harmonize God's freedom of choosing with the existence of eternal and necessary relations among things. Moreover, in Clarke's account, only intelligent entities can be properly understood as efficacious causes. Beings deprived of intelligence are not agents or efficacious causes at all and their effects are thus the result of the immediate action of some intelligent being operating upon them. (shrink)

The concept of efficient causation originates with Aristotle, who states that the types of cause include ‘the primary source of the change or rest’. For Medieval Aristotelians, the scope of efficient causality includes creative acts. The Islamic philosopher Avicenna is an important contributor to this conceptual change. In his Metaphysics, Avicenna defines the efficient cause or agent as that which gives being to something distinct from itself. As previous studies of Avicenna's ‘metaphysical’ conception of the efficient cause attest, it takes (...) God as a model agent. This essay considers whether Avicenna's ‘metaphysical’ conception of the efficient cause applies to natural agents. It ultimately argues that Avicenna offers a unified view of the efficient cause, which includes both divine and natural agents. On this view, an efficient cause gives being to another and is simultaneous with its effect. While Avicenna's defence of this view is an important chapter in the history of the concept of the efficient cause, it is also of interest in its own right. By appeal to a version of the principle of sufficient reason, it challenges a widespread view that causes are temporally prior to their effects. (shrink)

RESUMEN La interpretación habitual de Descartes sostiene que la nueva ciencia cartesiana es resultado del remplazo, en las explicaciones científicas, de las causas finales y formales por las causas eficientes. Si bien dicha afirmación en líneas generales es correcta, se ha tendido a asumir que las causas eficientes no entrañan problema alguno. Este artículo desea cuestionar dicha asunción, poniendo de manifiesto una serie de problemáticas concernientes a la cognoscibilidad de las causas eficientes. ABSTRACT The common interpretation of Descartes argues that (...) the new science is a result of Cartesian replacement, in scientific explanations, of the final and formal causes by the efficient causes. While this statement is broadly correct, it has tended to assume that efficient causes do not imply any problem. This paper wishes to question this assumption, showing a number of problems concerning the knowability of efficient causes. (shrink)
