Socrates and Gregory Vlastos : the power of elenchos in the Gorgias.
Gregory Vlastos claims that in the Gorgias Socrates is confident that the elenchos is the only and the final arbiter of moral truth. Traditionally, the object of elenchos has been viewed as not one of moral truth, but one of simply revealing to Socratic interlocutors confusions and muddles within themselves, thereby jarring their unquestioning adherence to some moral dogma. On Vlastos\u27 view, however, Socrates claims that he proves by elenchos that an interlocutor\u27s thesis is false. How can he, when in point of logic all he has proved is that the thesis is inconsistent with the agreed-upon premises in that argument whose truth Socrates does not undertake to establish? While Vlastos attempts to solve what he calls the problem of elenchos with all the ingenuity that we have come to expect from him, I argue that there are two major obstacles in his way. First, elenchos is not the only arbiter of moral truth in the Gorgias Socrates has a number of other reasons for believing certain things, but according to Vlastos, Socrates looks to elenchos, and to nothing but that, for the truth of his beliefs. I argue that, first, Vlastos\u27 characterization of elenchos is unsatisfactory, for on his criteria it is difficult to distinguish it from other kinds of arguments. This in turn seriously hampers a proper evaluation of elenctic arguments. I then show that at least in this dialogue Socrates has certain religious beliefs that he holds without relying on elenchos, and so elenchos is not the only avenue for acquiring moral knowledge. Under Vlastos\u27 correcting lenses, Socrates emerges also as a morally upright philosopher who would never knowingly conduct fallacious arguments. I argue that Socrates cheats at elenchos, and he does so in order to win over his interlocutors. I conclude that because of certain assumptions Vlastos makes about the character of the model philosopher and the model method, he exaggerates the strength of elenchos. If I am right, the Gorgias is witness to, not the power of elenchos as Vlastos would have us believe, but its limitations
Eighty-One Percent of Unrepaired Interportal Capsulotomies Showed Healed Capsules on Magnetic Resonance Imaging 5 Years After Primary Hip Arthroscopy
Purpose: To evaluate whether unrepaired interportal capsulotomy presents with capsular defect on magnetic resonance imaging (MRI) 5 years after primary hip arthroscopy and to determine its effect on functional results and findings of osteoarthritis on radiographs or MRI scans. Methods: Patients with femoroacetabular impingement (without arthritis or dysplasia) were retrospectively reviewed after arthroscopic labral repair or debridement and femoroplasty through interportal capsulotomy without closure. Patients were assessed preoperatively and at a minimum of 5 years postoperatively using patient-reported outcomes (Hip Outcome Score–Activities of Daily Living scale, modified Harris Hip Score, and visual analog scale pain score), radiographic measures, and MRI scans. Results: Forty patients (42 hips) were deemed eligible for the study and were evaluated. Of the hips, 81% had healed capsules, whereas 8 (19%) had capsular defects on the latest MRI scan. There were 3 hips with subchondral edema in the defect group compared with 1 in the healed-capsule group (P = .01) on the latest MRI scan, which was not present on preoperative MRI (still positive on multivariate analysis when the preoperative alpha angle was also taken into consideration). Functional results did not differ between the groups (P > .05). Conclusions: In this study, 81% of interportal capsulotomies healed without repair at 5 years after primary hip arthroscopy. Clinical Relevance: Understanding the prevalence and implications of unhealed capsulotomies could encourage surgeons to be meticulous in capsular closure
