Given the available evidence, I argue that we face considerable uncertainty about free will. In particular, I argue that the available philosophical evidence does not support being highly confident in our theories about the nature of free will, though this does not necessarily mean that we should suspend judgment about either incompatibilism or compatibilism. For those who accept incompatibilism, however, I argue that there is enough uncertainty about libertarian free will that they should suspend judgment about whether we are ever (...) free, if not reject free will entirely. While I do not claim that compatibilists should be similarly agnostic about the existence of free will, I argue that most compatibilist theories are subject to considerable uncertainty as well, so that most compatibilists should be agnostic about how often we act freely. I conclude with a brief discussion of how we might address these issues going forward. (shrink)

ArgumentIn 1877, a young mathematician named Joseph Boussinesq presented amémoireto theAcadémiedes sciences which demonstrated that some differential equations may have more than one solution. Boussinesq linked this fact to indeterminism and to a possible solution to the free will versus determinism debate. Boussinesq's main interest was to reconcile his philosophical and religious views with science by showing that matter and motion do not suffice to explain all there is in the world. His argument received mixed criticism that addressed both his (...) philosophical views and the scientific content of his work, pointing to the physical “realisticness” of multiple solutions. While Boussinesq proved to be able to face the philosophical criticism, the scientific objections became a serious problem, thus slowly moving the focus of the debate from the philosophical plane to the scientific one. This change of perspective implied a wide discussion on topics such as instability, the sensitivity to initial conditions, and the conservation of energy. The Boussinesq debate is an example of a philosophically motivated debate that transforms into a scientific one, an example of the influence of philosophy on the development of science. (shrink)

The trick, of course, is to pick your targets carefully: they should be central to the mainstream of contemporary philosophy, not marginal. Watkins has certainly done that. The target he has chosen is the problem of causation. His three-part aim is, first, to embed Kant’s theory of causation in its 18th century pre-Critical and especially Leibnizian setting; second, to argue that Kant’s Critical theory of causation is not in fact a reply to Hume, and that Kant’s metaphysics of causation depends (...) as much on the Third Analogy of Experience and the Third Antinomy of Pure Reason as it does on the Second Analogy; and third, that reconsidering Kant’s Critical metaphysics of causation from a pre-Critical and rationalist point of view can contribute to a serious reconsideration of the theory of agent causation in the contemporary debate about free will.

This paper examines Fichte's conception of the freedom of choice in Das System der Sittenlehre of 1798 as a solution to the dilemma posed by determinism and indeterminism. It show that Fichte does not simply affirm an indifferent power of voluntary choice, but demonstrates how such a power might co-exist with the measure of regularity and lawfulness we normally admit of human choices. Particular choices do not occur at random, but are based on general reasons. These reasons are in turn (...) based on the extent to which we have freely reflected on our original drive. Thus our choices can be comprehended and predicted from the point of reflection from which we choose. This does not lead to the denial of the freedom of choice, but only to rethinking it in terms of the freedom of reflection: Though we cannot choose other than what we choose from the point of reflection we occupy, we can choose other than what we choose by raising or lowering ourselves through reflection to a higher or lower point of reflection.
