Human excellences such as intelligence, morality, and consciousness are investigated by philosophers as well as artificial intelligence researchers. One excellence that has not been widely discussed by AI researchers is practical wisdom, the highest human excellence, or the highest, seventh, stage in Dreyfus’s model of skill acquisition. In this paper, I explain why artificial wisdom matters and how artificial wisdom is possible (in principle and in practice) by responding to two philosophical challenges to building artificial wisdom systems. The result is (...) a conceptual framework that guides future research on creating artificial wisdom. (shrink)

This thesis comprises a study of the ethical thought of Iris Murdoch with special emphasis, as evidenced by the title, on how morality is intimately connected to self-improvement aiming at perfection and how the study of fiction has an important role to play in our strive towards bettering ourselves within the framework set by Murdoch’s moral philosophy.

The problem of act individuation is a debate about the identity conditions of human acts. The fundamental question about act individuation is: how do we distinguish between actions? Three views of act individuation have dominated the literature. First, Donald Davidson and G.E.M. Anscombe have argued that a number of different descriptions refer to a single act. Second, Alvin Goldman and Jaegwon Kim have argued that each description designates a distinct act. Finally, Irving Thalberg and Judith Jarvis Thomson have averred that (...) some acts are sequences of causally related events, which include both a primitive bodily action and some of its effects. All of these accounts have assumed that a simple invariantist account of act individuation captures how ordinary people distinguish between acts. For my dissertation, I devised an experiment to test the action theorists' assumptions. My data show that people's intuitions seem to depend on the valence of the consequences of the action under consideration. So, an invariantist account is not possible. In light of the empirical results, I argue that if we seek a folk account of act individuation, then that account should be able to explain the variability that seems to be present in people's intuitions about different cases.

Aristotelian ethics has the resources to address a range of first as well as second order ethical questions precisely in those areas in which Kantian ethics is traditionally supposed to be weak. My aim in this chapter is to examine some of these questions, narrowing my remit to those concerning the nature of the good and the authority of norms. In particular, I want to motivate and sketch a non-naturalist Kantian response to the neo-Aristotelian challenge that targets specifically its meta-ethical (...) and meta-normative naturalistic assumptions.

Auguste Comte's doctrine of the three phases through which sciences pass (the theological, the metaphysical, and the positive) allows us to explain what John Stuart Mill was attempting in his magnum opus, the System of Logic: namely, to move the science of logic to its terminal and 'positive' stage. Both Mill's startling account of deduction and his unremarked solution to the Humean problem of induction eliminate the notions of necessity or force—in this case, the 'logical must'—characteristic of a science's metaphysical (...) stage. Mill's treatment had a further surprising payoff: his solution to the Problem of Necessity (what today we call the problem of determinism and freedom of the will). (shrink)

Some species are weedy: they move from one ecological niche to another. Other species are specialized: they are exquisitely adapted to exploit a particular niche. Human beings are the design solution in which a species is simultaneously weedy and specialized - the trick being to manage the exquisite niche-specific adaptations in software rather than in the hardware. We are built to reprogram ourselves on the fly, to select new goals, new priorities and new guidelines appropriate to novel niches. Understanding ourselves (...) as an implementation of this design solution has consequences for the theory of practical reasoning. Instrumentalism (the theory of practical reasoning according to which it consists solely in selecting means to pre-given ends) cannot be a suitable theory of rationality for such a species (that is, our own).

Hard Truths is an important book in its own right. It is also the latest contribution to a complex and impressive project that Elijah Milligram has been developing from his first book onwards. There he characterized practical induction as a type of reasoning that enables agents to learn from experiences of the new and the unfamiliar, agents whose inferences are from beliefs that they have formed either ‘in ways that have a suitable amount to do with [their] truth’, or, when (...) ‘the appeal to truth is unhelpful’, in ways that underwrite such inferences as they are committed to drawing . In his introduction to his anthology on practical reasoning, Millgram catalogued the presently competing theories of practical reasoning, posing the question: what kind of reasoning should we employ in deciding between the claims of rival theories? The subtitle of his third book , ‘Practical Reasoning as a Foundation for Moral Theory’, already suggests its central thesis, that we should first survey the range of theories of practical reasoning , should then identify which moral theory it is with which each theory of practical reasoning is paired , should next decide which theory of practical reasoning is correct , and, finally, should adopt the moral theory paired with that theory of practical reasoning. There are at least three clusters of problems that badly need extended attention, if the claims of these three books are to be sustained: one concerning the account of truth presupposed by Millgram, a second to do with the inferences that we need to employ, and a third concerning the unity of reasoning agents. All three provide Hard Truths with subject-matter, but Millgram’s principal focus is …. (shrink)

Nietzsche thought at one point that predication originated through the misapplication of names for particulars to further particulars. I doubt myself that this is where the device came from, although one does occasionally encounter usage – such as ‘another Vietnam’ – that evidently does arise in this manner. However, his account of predication is a useful model for a more sophisticated device which we in fact deploy, namely, the intentional misdescription of one circumstance or another in the interests of expedited (...) inference, often via the misapplication of a predicate. I don’t believe that ‘… is a leaf’ is a systematic reapplication of the name of some ur-leaf, but just the other day, I told my gardener that the leaves were off the tree, and that she could come in and work on my pond. I was triggering an inference rule we both accept: that you schedule fall cleanup once the leaves are off the tree. Rather than describe the actual state of the tree , and then renegotiate the rule to match, it was simpler to work with the misdescriptions. My respondents recall that devices such as predication are flexible anyway; they conclude that there is no need to misapply them. Let me try to get you to think twice about the assumption that flexibility pre-empts misapplication. But as I proceed, bear in mind that my illustrations are not intended as an argument. Any given illustration can be read either as a misapplication of a description, or alternatively as a correct application of a predicate, whose use in context is controlled by, perhaps, the sort of techniques discussed by David Lewis ….
