Thought insertion is a condition characterized by the impression that one's thoughts are not one’s own and have been inserted by others. Some have explained the condition as resulting, in part, from impaired or defective self-knowledge, or knowledge of one’s mental states. I argue that such models do not shed light on the most puzzling feature of thought insertion: the patient’s experience that an introspected thought does not feel like her own. After examining ways in which existing versions of the (...) model might address this worry, I propose a significant modification. I argue that the experience of disownership consists in a rational indifference that one feels towards one’s inserted thought. I further contend that the experience is generated by an underlying absence of an expectation of rational authority towards the inserted thought, such that the patient does not expect her thought to reflect, or be shaped by, her own rational considerations. I defend my proposal using empirical studies from cognitive and social psychology which suggest that we ordinarily have and experience an expectation of rational authority towards a certain subset of our thoughts, and direct analysis of patient reports, which strongly suggest that it is this expectation and the corresponding experience that thought insertion patients lack.

Pre-natal genetic enhancement affords us unprecedented capacity to shape our skills, talents, appearance and perhaps subsequently the quality of our lives in terms of overall happiness, success and wellbeing. Despite its powerful appeal, some have raised important and equally persuasive concerns against genetic enhancement. Sandel has argued that compassion and humility, themselves grounded in the unpredictability of talents and skills, would be lost. Habermas has argued that genetically altered individuals will see their lives as dictated by their parents’ design and (...) therefore will not acquire an appropriate self-understanding. How should we view enhancement efforts in light of these concerns? I propose that we begin by adopting a defeasibility stance. That is, I ask whether our belief that genetic enhancements serve in the best interests of the child is reason to genetically enhance, underscoring a sort of epistemic vulnerability. I utilize the epistemological notions of defeasible reasons, undercutting and overriding defeaters in order to better understand and systematically evaluate the force of such concerns. I argue that close examination of both objections using this framework shows that we have reason to enhance, a reason that is defeasible but as yet, undefeated. (shrink)

Some have recently argued that parents are morally obligated, under certain circumstances, to use pre-natal genetic intervention as a means of enhancement. Despite aiming to benefit the child, such intervention may produce serious and irreparable harm. In these cases, parents seem to have an obligation not to intervene, as such efforts make the child worse off. Julian Savulesu has argued that while harm raises doubts about the acceptability of genetic enhancement, genetic selection remains an obligation. This claim, however, rests on (...) an indefensible privileging of personal over impersonal harm. I propose instead that we reframe the debate as stemming from fundamentally different views about parental obligation. The objection from harm rests on an objectivist conception, according to which obligation is determined by all relevant facts, including unpredictable harm. Proponents of genetic enhancement, however, operate within subjectivist assumptions about obligation, according to which moral requirements are determined by reasons that are epistemically accessible to the relevant agents. I will argue here that because subjectivism offers a more reasonable conception of parental obligation, such unforeseeable harm does not remove a parent’s obligation to enhance. (shrink)

Duncan Pritchard has recently argued that a certain brand of virtue epistemology, known as “virtue responsibilism”, cannot account for knowledge acquired through the use of tacit reasoning processes. I defend virtue responsiblism by showing that Pritchard's charge is founded on a mischaracterization of the view. Contra Pritchard, responsibilists do not demand that agents have complete access to the grounds for their beliefs in order to know. A closer examination of prominent accounts of virtue responsiblism, including Zagzebski's and Hookway's, reveals that (...) the accessibility requirement is much weaker than Pritchard presumes. Zagzebski maintains that it is only intellectually virtuous motivations which drive the agent to adopt truth-conducive procedures and habits that must be accessible, rendering the agent responsible for her belief. Hookway writes that agents may display virtue not by actively monitoring or accessing each step of their deliberation, but by allowing deeply embedded intellectual traits t.. (shrink)
