We consider the current debate between bioconservatives and their opponents—whom we dub bioliberals—about the moral acceptability of human enhancement and the policy implications of moral debates about enhancement. We argue that this debate has reached an impasse, largely because bioconservatives hold that we should honour intuitions about the special value of being human, even if we cannot identify reasons to ground those intuitions. We argue that although intuitions are often a reliable guide to belief and action, there are circumstances in (...) which they are not reliable. Intuitions—including intuitions about enhancement—are subject to various cognitive biases rendering them unreliable in some circumstances. We argue that many bioconservative intuitions about enhancement are examples of such unreliable intuitions. Given this, it is unrealistic of bioconservatives to expect others to rely on their unexamined intuitions. Furthermore, refusing to engage in debates about the reasons and values that underpin their intuitions about enhancement will have the effect of making bioconservative voices less relevant in policy debates about enhancement than they would otherwise be.

Is it conceptually possible for an event, L, to be the cause of an earlier event, E? Some writers have employed the so-called bilking argument to attempt to show that the idea of such backwards causation is incoherent . According to this argument, if we are presented with what someone claims to be a case of backwards causation, it would be possible in principle to wait for E to occur, and then intervene to prevent the occurrence of L, thus demonstrating (...) that E could not have been caused by L after all. Moreover, if our attempts to bilk L-type events having observed E-type events always fail, we have grounds to argue that any causal relationship between the two is not one of backwards causation, but of ordinary, forwards, earlier-to-later causation.Does the bilking argument succeed in showing backwards causation to be incoherent? Before answering this question, let us deal with a far simpler reason for deeming backwards causation incoherent, whose elucidation now will be useful later. To those attracted to the view that temporal order is determined by causal order, 1 backwards causation may seem incoherent because on this view a cause is by definition earlier than its effect. I do not take issue with this view, and wish my conception of backwards causation to be compatible with it. 2 By ‘backwards causation’, I mean causation that runs in the opposite direction to some other causal processes, such that the temporal order entailed by such backwards causation is the reverse of that entailed by those other causal processes. In most philosophical discussions of backwards causation, we are at least implicitly given reasons to believe that these other causal processes dictate the …. (shrink)

The conviction that high self-esteem is beneficial both to the individual and to society in general has been pervasive both in academia and in popular culture. If it is indeed beneficial, it is a prime candidate for pharmacological enhancement. There is evidence to suggest, however, that the benefits of high self-esteem to the individual have been exaggerated; and that there are few - if any - social benefits. With this evidence in mind, I consider in what ways high self-esteem is (...) valuable, and suggest how enhancement could play a role in maximising its valuable aspects. (shrink)

In her re-analysis of the evidence presented in Klein and Nichols (2012) to support their argument that patient R.B. temporarily lost possessory custody of consciously apprehended objects (in this case, objects that normally would be non-inferentially taken as episodic memory), Professor Roache concludes Klein and Nichols's claims are untenable. I argue that Professor Roache is incorrect in her re-interpretation, and that this is due, in part, to lack of sufficient familiarity with psychological theory on memory as well as clinical literature (...) on felt loss of ownership of one’s intentional objects.

Several philosophers have argued that human enhancements should be considered a potential solution to climate change. In this paper, I consider one such argument offered by S. Matthew Liao, Anders Sandberg, and Rebecca Roache. I argue that, while their argument is plausible, we have an even stronger reason to consider enhancements a potential solution. In particular, enhancements could align our interests with the promotion of a proper response to climate change: if enhancements were in our interest to adopt and also (...) reduced the pernicious effects of climate change, then it would, indirectly, become in our interest to reduce those effects.

Following Freud’s analysis of the fragile line between the uncanny double and its comic redoubling, I identify the doubling of the double found in critical moments of Hegelian dialectic as producing a kind of comic effect. It almost goes without saying that two provides greater pleasure than one, the loneliest number. Many also find two to be preferable to three, the tired trope of dialectic as a teleological waltz. Two seems to offer lightness, relieving one from her loneliness and lacking (...) the complications of a third who comes in between. And yet, we learn through Marx and Freud that the double (even the double of tragedy and farce) borders on something closer to horror than comedy. -/- In the following, I would like to explore why four is funnier than two in my staging of dialectic as the doubling of the double or, to borrow a movie title from Laurel and Hardy, “Twice Two” (Roach et al. 1933a). I will begin by exploring the formulations of the double in the form of a pair of opposites and in the form of a pair of twins. The literary tropes of the double as the odd couple, on one side, and the twins, on the other, appear to serve very different narrative functions, which incite different kinds of affective responses from the audience. However, the form of the opposed double sometimes conceals the realization that the empty or fragmented content of the first is only reduplicated in the second. The “straight man” of the odd couple cannot see himself in his counterpart “the comic.” The redoubling of the double, however, forces not only the audience, but the original double on stage to confront what was already present, but unrealized, from the beginning. To illustrate this redoubling of the double within the opening of Hegel’s Science of Logic, I consider two short films by Laurel and Hardy in which the comic duo redoubles itself. The formula (2 x 2) produces a comic excess through the dialectical redoubling of there uncanny double. (shrink)
