To reassure those concerned about wholesale discontinuity between human existence and posthumanity, transhumanists assert shared ground with antiquity on vital challenges and aspirations. Because their claims reflect key misconceptions, there is no shared vision for transhumanists to invoke. Having exposed their misuses of Prometheus, Plato, and Aristotle, I show that not only do transhumanists and antiquity crucially diverge on our relation to ideals, contrast-dependent aspiration, and worthy endeavors but that illumining this divide exposes central weaknesses in transhumanist argumentation. What is more, antiquity’s handling of these topics suggests a way through the impasse in current enhancement debates about human “nature” and helps to resolve a tension within transhumanists’ accounts of what our best moments signify about the ontological requirements for real flourishing.

From the standpoint of disability advocacy, further exploration of the concept of well-being stands to be availing. The notion that “welfarism” about disability, which Julian Savulescu and Guy Kahane debuted, qualifies as helpful is encouraged by their claim that welfarism shares important commitments with that advocacy. As becomes clear when they apply their welfarist frame to procreative decisions, endorsing welfarism would, in fact, sharply undermine it. Savulescu and Kahane's Principle of Procreative Beneficence—which reflects transhumanism, or advocacy of radical bioenhancement—morally requires parents to choose the child who will, in all probability, have “the best life.” Assuming the emergence of potent biotechnologies, procreative decision-making would be highly standardized, for prospective parents would be morally obliged to maximize select capacities, including intelligence, self-control, and hedonic set-point, in their children. Welfarism, applied to reproduction, is staunchly objectivist about what course is incumbent on decision-makers, giving no credence to first-personal values, aspirations, and experiences. Though this dismissal of individual perspectives applies to everyone, its implications for disability advocacy are especially severe. With that advocacy in view, greater attention to “well-being” should, therefore, be severed from the welfarism of Savulescu and Kahane.

Near the climax of the ascent passage of the Symposium, Plato describes how the lover turns to gaze at the great sea of the beautiful and. While the phrase has been variously interpreted by commentators and translators, none has regarded it as particularly significant. In what follows we examine the contribution that the immediate context makes to the meaning of the phrase and take note of the link between the adjective ἄφθονος and two subsequent uses of φθον⋯ω, both with reference to Alcibiades. We conclude that in the two final scenes of the dialogue the repetition of ἄφθονος and φθον⋯ω has the same effect as the repetition of the well-studied adverb ⋯ξα⋯φνης. By virtue of these contextual associations, we suggest, the prepositional phrase acquires a new significance. Furthermore, on the interpretation developed here the dialogue's two final scenes encapsulate the view of the incompatibility of jealousy and philosophy that Plato sets forth more explicitly and at greater length in the Phaedrus and Republic.
