It ofers an interesting proposal for rethinking the nature of the philosophy of medicine and its ofce in grounding and directing not just the medical humanities and bioethics cheap dapoxetine 60 mg visa, but medical eth- ics and medical professionalism order dapoxetine 90mg visa. Pellegrino has shaped the development of the philosophy of medi- cine, the medical humanities, bioethics, and medical ethics. The past would not have been the same in the absence of his scholarship and per- sonal engagement. His scholarship reaches to the future and to the pos- sibility of recapturing an authentic medical ethics, an ethics for the medical profession. Pellegrino’s work ofers a basis for approaching bioethics and the medical humanities afresh. By addressing core but underexamined is- sues in the philosophy of medicine, he indicates an avenue toward recov- ering a sense of commitment to virtue and service on the part of the medical profession. By recognizing the physician-patient relationship as the central, moral-epistemic context for medical ethics, he provides a teleological account of the practice of medicine in terms of its pursuit of the medical good of the patient. The project he has begun promises a deeper understanding of medicine, as well as an opportunity for recaptur- ing a moral sense of medical-professional identity. Pellegrino’s work thus points to the possibility of recapturing an in- tellectually vigorous medical ethics that, by being focused on the condi- tions for rightly directed medical professionalism and identity, will not be grounded merely in the concerns of bioethics. The essays collected here in particular ofer a better appreciation of how a philosophy of medicine can reorient physicians, the medical humanities, and bioethics to Hippocratic themes reshaped and sustained in a conceptual and moral framework that transcends the cultural context of Greece, which produced the Oath. Not only has Pellegrino creatively examined the foundations of a philosophy of medicine in the strict sense, but he has also shown how it can redirect the medical humanities and bioethics. In so doing, he has succeeded in ar- ticulating a vision of how medicine can meet the challenges of the future.
