- Bruce Edmonds (2004). Implementing Free Will. In D. N. Davis (ed.), Visions of Mind: Architectures for Cognition and Affect. IDEA Group Publishing.“The demonstration that no possible combination of known substances, known forms of machinery and known forms of force, can be united in a practical machine by which man shall fly long distances through the air, seems to the writer as complete as it is possible for the demonstration of any physical fact to be.” Simon Newcomb, Professor of Mathematics, John Hopkins University, 1901 Abstract Free will is described in terms of the useful properties that it could confer, explaining why it might have been selected for over the course of evolution. These are: exterior unpredictability; interior rationality; and social accountability. A process is described that might bring it about when deployed in a suitable social context. It is suggested that this process could itself be of an evolutionary nature – that free will might “evolve” in the brain during development. This mental evolution effectively separates the internal and external contexts, whilst retaining the coherency between individual’s public accounts of their actions. This is supported by the properties of evolutionary algorithms and possesses the three desired properties. Some objections to the possibility of free will are dealt with by pointing out the prima facie evidence and showing how an assumption that everything must be either deterministic or random can result from an unsupported assumption of universalism.

What does free will mean to laypersons? The present investigation sought to address this question by identifying how laypersons distinguish between free and unfree actions. We elicited autobiographical narratives in which participants described either free or unfree actions, and the narratives were subsequently subjected to impartial analysis. Results indicate that free actions were associated with reaching goals, high levels of conscious thought and deliberation, positive outcomes, and moral behavior (among other things). These findings suggest that lay conceptions of free will fit well with the view that free will is a form of action control.
Free enterprise economic systems evolved in the modern period as culturally transmitted values related to honesty, hard work, and education achievement emerged. One evolutionary puzzle is why most economies for the past 5,000 years have had a limited role for free enterprise given the spectacular success of modern free economies. Another is why if humans became biologically modern 50,000 years ago did it take until 11,000 years ago for agriculture, the economic foundation of states, to begin. Why didn’t free enterprise evolve long ago and far away?
It is widely held that free speech is a distinctive and privileged social kind. But what is free speech? In particular, is there any unified phenomenon that is both free speech and which is worthy of the special value traditionally attached to free speech? We argue that a descendent of the classic Millian justification of free speech is in fact a justification of a more general social condition; and, via an argument that 'free speech' names whatever natural social kind is justified by the best arguments, that free speech is therefore this more general condition. This condition involves not merely the orthodox freedom (in some sense) of speakers to distribute words, but also two less frequently acknowledged dimensions of free speech: audience understanding and consideration. We conclude with some discussion of the policy implications of this conception of free speech.
There has been much controversy over whether the claims of evolutionary psychologists, if true, imply that we humans are significantly less free than has traditionally been thought. This in turn gives rise to the concern that excuses are being given to philanderers and other ne’er-do-wells for their behaviour. Evolutionary psychologists themselves often respond to this concern by claiming that it presupposes that they believe in genetic determinism, which they do not. Philosophers, such as Janet Radcliffe Richards in Human Nature after Darwin, respond by appealing to compatibilist accounts of free will. The thought is that whether or not our behaviour is caused by evolved mental mechanisms, has no bearing on whether or not it is free. The present paper takes issue with this use of compatibilist arguments. Compatibilist accounts of free will do not just say that an action can be determined and still free; they also distinguish between situations where we are free and ones where we are not. The latter includes not just situations of external coercion, but also situations where there are internal obstacles such as compulsion, addiction or self-deception. While not attempting to outline a full account of what it is to be free, this paper will outline one set of conditions which are sufficient for our freedom to be said to be restricted – conditions which are shared by situations of addiction, self-deception, etc. But a central pillar of evolutionary psychology is that the mind consists wholly or largely of modules whose operation is mandatory. The outputs of these modules are often characterised as desires or goals. It will be argued that this implies internal obstacles to free will that are relevantly similar to the obstacles of addiction, self-deception, etc. It is ultimately a scientific question, and hence outside the scope of this paper, whether the relevant evolutionary-psychological claims are true or not. However, they are central to the discipline, and this paper will argue that if they are true that has negative consequences for how free we are. Hence, the view that evolutionary psychology implies that we are less free than has traditionally been thought is not without foundation.
This paper explores the possibility that chaos theory might be helpful in explaining free will. I will argue that chaos has little to offer if we construe its role as to resolve the apparent conflict between determinism and freedom. However, I contend that the fundamental problem of freedom is to find a way to preserve intuitions about rational action in a physical brain. New work on dynamic computation provides a framework for viewing free choice as a process that is sensitive and unpredictable, while at the same time organized and intelligent. I conclude that this vision of a chaotic brain may make a modest contribution to an intuitively acceptable physicalist account of free will.
This paper criticizes the assumption,omnipresent in contemporary philosophy ofreligion, that a perfectly good and loving Godwould wish to confer on (at least some) finitepersons free will. An alternative mode ofDivine-human relationship is introduced andshown to be as conducive to the realization ofvalue as one involving free will.Certain implications of this result are thenrevealed, to wit, that the theists free willdefence against the problem of evil isunsuccessful, and what is more, that free will,if it exists, provides positive support foratheism.
Abstract: Contextualist accounts of free will recently proposed by Hawthorne and Rieber imply that the same action can be both free and unfree (depending on the attributor's context). This paradoxical consequence can be avoided by thinking of contexts not as constituted by arbitrary moves in a conversation, but rather by (relatively stable) social practices (such as the practices of attributing responsibility or of giving scientific explanations). The following two conditions are suggested as each necessary and jointly sufficient for free will: (i) the agent is able to form considered practical judgements and to act accordingly, and (ii) the agent (or some agent-involving event) is the original cause of her actions. A contextualist reformulation of the second condition is developed according to which only contexts in which responsibility is attributed are relevant for the kind of original causation required for free will, which allows for a non-relativist contextualism about free will.
Determinism seems incompatible with free will. However, even indeterminism seems incompatible with free will, since it seems to make free actions random. Popper contends that free agents are not bound by physical laws, even indeterministic ones, and that undetermined actions are not random if they are influenced by abstract entities. I argue that Popper could strengthen his account by drawing upon his theories of propensities and of limited rationality; but that even then his account would not fully explain why free actions are not random. I offer a solution to this problem which draws on Hornsby’s analysis of action. I then borrow an idea of Kant about self-consciousness to distinguish free agents from sub-human animals. I make a brief evaluation of Popper’s contribution.
Some practical criteria for free-will are suggested where free-will is a matter of degree. It is argued that these are more appropriate than some extremely idealised conceptions. Thus although the paper takes lessons from philosophy it avoids idealistic approaches as irrelevant. A mechanism for allowing an agent to meet these criteria is suggested: that of facilitating the gradual emergence of free-will in the brain via an internal evolutionary process. This meets the requirement that not only must the choice of action be free but also choice in the method of choice, and choice in the method of choice of the method of choice etc. This is directly analogous to the emergence of life from non-life. Such an emergence of indeterminism with respect to the conditions of the agent fits well with the `Machiavellian Intelligence Hypothesis' which posits that our intelligence evolved (at least partially) to enable us to deal with social complexity and modelling `arms races'. There is a clear evolutionary advantage in being internally coherent in seeking to fulfil ones goals and unpredictable by ones peers. To fully achieve this vision several other aspects of cognition are necessary: open-ended strategy development; the meta-evolution of the evolutionary process; the facility to anticipate the results of strategies; and the situating of this process in a society of competitive peers. Finally the requirement that reports of the deliberations that lead to actions need to be socially acceptable leads to the suggestion that the language that the strategies are developed within be subject to a normative process in parallel with the development of free-will. An appendix outlines a philosophical position in support of my position.
