AbstractThe notion of a “World of Images” located somewhere between the immaterial and the material world was a mainstay of eschatological speculation in late medieval Islam. As has been recognised before, the concept was launched by al-Suhrawardī (d. 1191). However, its more properly philosophical underpinnings, in particular the notion of “suspended” images – images which somehow have an objective, rather than just a mental or subjective, status – merit further clarification, which this article attempts to provide. Since the concept of “suspended forms”, while applied to eschatological matters in the last treatise of the Philosophy of Illumination, makes its first appearance in a discussion of mirror vision, I examine in some detail Avicenna's understanding of mirror vision as presented in the Shifāʾ, to which al-Suhrawardī reacts. I then undertake a detailed reconstructive analysis of two paragraphs of the Philosophy of Illumination, paying particular attention to the question of the ontological status of “suspended” or “self-subsistent” images as well as to the idea that mirrors serve, not as loci in which images inhere, but as loci at which they become manifest (singular maẓhar).

AbstractIn this paper it is argued that the conceptions of embodied meaning and of intuition that Hegel appeals to in the Aesthetics anticipate some of Merleau-Ponty’s insights concerning the distinctive character of pre-conceptual, sensuous forms of meaning. It is argued that, for Hegel, our aesthetic experience of the beautiful is such that we cannot readily differentiate in it the purportedly distinct roles that sensation and thought play, and so that the account of sensuous intuition operative here differs from the one appealed to in more familiar, ‘intellectualist’ conceptions that are premised upon our being able to make such a distinction. Some of Merleau-Ponty’s phenomenological insights are brought to bear to help support and illuminate some of the implications of Hegel’s conception of such sensuously embodied meaning.

Standard models of cognition are built from abstract, amodal, arbitrary symbols, and the meanings of those symbols are given solely by their interrelations. The target article (Glenberg 1997t) argues that these models must be inadequate because meaning cannot arise from relations among abstract symbols. For cognitive representations to be meaningful they must, at the least, be grounded; but abstract symbols are difficult, if not impossible, to ground. As an alternative, the target article developed a framework in which representations are grounded in perception and action, and hence are embodied. Recent work (Glenberg & Robertson 1999; 2000; Glenberg & Kaschak 2002; Kaschak & Glenberg 2000) extends this framework to language.

Background: Evaluation and management of osteochondral lesions of the talus (OLTs) often warrant advanced imaging studies, especially in revision or cases with cystic defects. It is possible that orthopedic surgeons may overestimate the size and misinterpret the morphology of OLT from conventional computed tomography (CT), thereby influencing treatment strategies. The purpose of this study was to determine the utility of a novel means to estimate the true-volume of OLTs using 3D reconstructed images and volume analysis. Methods: With Institutional Review Board approval, an institutional radiology database was queried for patients with cystic OLTs that failed previous microfracture, having compatible CT scans and magnetic resonance imaging (MRI) between 2011 and 2016. Fourteen patients met inclusion criteria. Of these, 5 cases were randomly selected for 3D CT reconstruction modeling. Ten orthopedic surgeons independently estimated the volume of these 5 OLTs via standard CT. Then 3D reconstructions were made and morphometric true-volume (MTV) analysis measurements of each OLT were generated. The percent change in volumes from CT were compared to MTVs determined from 3D reconstructive analysis. Results: On average, the volume calculated by conventional CT scanner grossly overestimated the actual size of the OLTs. The volume calculated on conventional CT scanner overestimated the size of OLTs compared to the 3D MTV reconstructed analysis by 285% to 864%. Conclusions: Our results showed that conventional measurements of OLTS with CT grossly overestimated the size of the lesion. The 3D MTV analysis of cystic osteochondral lesions may help clinicians with preoperative planning for graft selection and appropriate volume while avoiding unnecessary costs incurred with overestimation. Level of Evidence: Level IV, case series.

Background: Osteochondral lesions of the talus (OLT) often require advanced imaging if they prove to be refractory to preliminary microfracture. Orthopedic surgeons may misinterpret the size and morphology of the OLT when evaluating through conventional methods. The purpose of this study was to evaluate MRI as a modality for calculating true-volumes and compare its utility to that of CT true-volume and conventional methods of measuring lesion size. Methods: With IRB approval, an institutional radiology database was queried for patients with cystic OLT that had undergone and failed microfracture and had compatible CT and MR scans between 2011 and 2016. Five lesions, previously analyzed and described in the literature using CT true-volume, were selected. 10 orthopedic surgeons independently estimated the volume of these 5 OLT via standard MRI. Next, 3D reconstructions were created and morphometric true-volume (MTV) analysis measurements of each OLT were generated. The percent change in volumes from CT and MR was compared based upon MTVs determined from 3D reconstructive analysis. Results: The volume calculated using conventional methods in CT and MR scans grossly overestimated the size by of the OLT by 285-864% and 56-374% respectively when compared to 3D true-volume analysis of those CT and MR scans. Conclusions: This study demonstrates that true-volume is more accurate for calculating lesion size than conventional methods. Additionally, when comparing MRI and CT, thin slice CT true-volume is superior to MRI true-volume. True-volume calculation improves accuracy with CT and MRI and should be recommended for use in revision OLT cases. Levels of Evidence: Level III: Case control study
