Daniel Dennett—Robert Kane: Free Decisions and Retrospection

Daniel Dennett’s dispute with Robert Kane over free will turns on where a free decision can be found and what could make it a genuine beginning. Dennett argues that searching physical reality for a discrete, foundational act of choice leads to a regress, not to a self that can be isolated among other events. The alternative is not to excuse action as causally determined: responsibility attaches to the subject’s relation to the history and constellation through which a particular choice takes shape.

The search for a foundational decision

Kane’s account, as presented here, seeks a regress-stopper: some action in an agent’s life history for which the agent’s motives and will were not already set in one direction. If responsibility for later acts requires such a founding free act, the question immediately returns: what earlier act made that one free? The attempt to identify an ultimate origin threatens to send the explanation backward through the agent’s decisions without locating a point at which the regress can securely end.

Dennett’s critique begins by distinguishing physical reality from what he calls the design level. A physical inventory may disclose elements, processes, and qualities, but no particular item among them directly is the Self. The self exists at the design level as an ideal entity, rather than as an empirically isolable object alongside other objects. On this account, locating a free decision as a special physical event mistakes the level at which the question can be answered.

The regress and its analogies

The argument’s image of the primal mammal makes the regress vivid. If every mammal must have a mammal for a mother, the reasoning seems to leave no place for the first mammal, which could not itself have a mammal mother. Dennett’s analogy is that Kane’s demand for a founding free action risks the same structure: a decision is treated as free only if earlier decisions ground it, while those earlier decisions in turn call for their own grounding.

The discussion sets out that difficulty through a chain of choices. A present decision to go or stay is described as up to the agent because its recent antecedents were up to the agent; those antecedents, in turn, were up to the agent because of their own antecedents. Yet pursuing this chain far enough backward does not reveal a single point where an independent self can be found, spatially and temporally separated from the decisions attributed to it. Past events may not have been up to the agent, but the search for a clean boundary between inherited conditions and a wholly self-originating act does not solve the problem.

Luther and the appearance of necessity

Martin Luther’s declaration, “Here I stand. I can do no other,” gives the abstract question a historical and ethical form. His act of posting theses against the Pope and triggering the Protestant break seems to pose a stark choice: if he could not have done otherwise, was the act free? The argument refuses to settle the matter by looking for earlier moments in Luther’s life when he supposedly experienced a pure freedom to choose otherwise. Such a search would reproduce the same demand for a decisive point outside the chain of conditions.

Instead, the account locates responsibility in the subject’s relation to the constellation in which the act appears inevitable. Luther’s inability to do otherwise, as the act presents itself to him, does not by itself establish that he is absolved of responsibility. Freedom does not require an earlier, unconditioned decision that magically interrupts causality; it concerns the subject’s responsibility for the very configuration through which a particular decision assumes the form of necessity.

Retrospective responsibility and the wider argument

The contrast with Hegel’s treatment of the Kantian gap clarifies the form of this reasoning. Rather than seeking to overcome a division by positing a further domain beyond it, the argument treats the gap as internal to the structure under examination. The problem is not solved by discovering a hidden, fully constituted self behind the observable decisions. As in the move from an epistemological obstacle to a positive condition, the failure to find the self as one more physical item points toward a limit in the picture of reality being used, not merely toward missing evidence.

This does not make responsibility a matter of an empirically discoverable first cause. The subject is held responsible for the constellation within which an action becomes intelligible as an unavoidable choice, even though no single decision in the past supplies an absolute foundation for it. Dennett’s challenge to Kane therefore shifts the question from where a free act occurs to how agency and responsibility are attributed across a history of decisions. The regress exposes the weakness of treating freedom as a special event lodged inside physical reality; the proposed alternative preserves responsibility without requiring that such an event be found.
