In recent years, the interest in theory which has once been a moving force of academic research in the field of literary studies appears to have decreased. The status of theory, its relevance and appropriateness for the understanding of literature have been put into doubt. Faced with this observation, some critics have even suggested that we have now entered into a new era of research which can retrospectively be identified as the era "after theory". Against the background of such pronouncements and to a certain extent in opposition to them, the investigations proposed here wish to uphold the idea of the utility and indeed the need for theoretical approaches to literature. To appreciate the status of theory and its possible contribution to a deepened understanding of literature, it is useful not to focus exclusively on the distinction or supposed divide between literature and theory. Instead we should pay attention to what links and unites them. This common ground or common denominator of literature and theory consists in the dimension of language. Furnishing, so to speak, the intellectual material from which both domains of articulation are formed, language constitutes at once the key element of literature and a principal concern of theory.

Background: Due to the difficulties in the definite diagnosis, data on brain imaging in pediatric patients with central nervous system (CNS)-invasive mold infection (IMD) are scarce. Our aim was to describe brain imaging abnormalities seen in immunocompromised children with CNS-IMD, and to analyze retrospectively whether specific imaging findings and sequences have a prognostic value. Methods: In a retrospective study of 19 pediatric patients with proven or probable CNS-IMD, magnetic resonance imaging (MRI)-findings were described and analyzed. The results were correlated with outcome, namely death, severe sequelae, or no neurological sequelae. Results: 11 children and 8 adolescents (11/8 with proven/probable CNS-IMD) were included. Seven of the patients died and 12/19 children survived (63%): seven without major neurological sequelae and five with major neurological sequelae. Multifocal ring enhancement and diffusion restriction were the most common brain MRI changes. Diffusion restriction was mostly seen at the core of the lesion. No patient with disease limited to one lobe died. Perivascular microbleeding seen on susceptibility weighted imaging (SWI) and/or gradient-echo/T2* images, as well as infarction, were associated with poor prognosis. Conclusions: The presence of infarction was related to poor outcome. As early microbleeding seems to be associated with poor prognosis, we suggest including SWI in routine diagnostic evaluation of immunocompromised children with suspected CNS-IMD.

Comparatists have always had misgivings about the concept of comparison. The status accorded to comparison within Comparative Literature is far from dear. Although the discipline's very name derives from the concept, we are not quite sure what comparison refers to. Does it define what we do? Does it delineate a field of study, a range of objects?

Theory's engagement with language on the one hand, with literature's potential to generate knowledge that is theoretically relevant on the other, has a long history. One of its roots lies in the approach to culture and society developed by enlightenment anthropology and philosophy. In this paper Christian Moser intends to analyze the function attributed to language in eighteenth-century theories of the origin of culture and society. What we nowadays call 'cultural theory' is genealogically related to these early investigations into the constitution of human society. Social theories of the enlightenment first emerged in the contexts of a secularized universal history and the nascent discourses of anthropology and the philosophy of history. They often took the form of a 'conjectural history': speculations about the origin of society and its institutions; the origin of government, of law, and of social inequality; all of them linked systematically to the origin of language. While present-day cultural theory no longer harbours this obsession with origins, it still carries with it a rich legacy of enlightenment thought, not least its idea that social structure and linguistic structure are interconnected. Therefore it seems apposite to trace back current 'languages of theory' to eighteenth-century 'theories of language' and their interplay with 'theories of society.'

Terry Eagleton stellt in seinem kleinen Büchlein über Shakespeare eine provozierende These hinsichtlich der Bedeutung der Hexen in 'Macbeth' auf: "The witches", so behauptet er, "are the heroines of the piece, […] however much the critics have set out to defame them" (Eagleton 1986, 2). Die Hexen sind die eigentlichen Heldinnen des Dramas - und das, obwohl, ja gerade weil sie als bloße Randfiguren in Erscheinung treten. Denn die Hexen werden in 'Macbeth' gezielt in einem Schwellen- und Randbereich der kulturellen und sozialen Ordnung plaziert - "its shadowy borderlands". Genauer: Als ambivalentes Grenzphänomen stellen sie das Funktionieren der kategorialen Oppositionen in Frage, die diese Ordnung begründen. Die Welt der Hexen ist keine böse und häßliche Gegenwelt zu der durch vernünftige Gesetze strukturierten, durch göttliche Autorität legitimierten Welt der Menschen. Vielmehr hebt sie den fundierenden Gegensatz zwischen gut und böse, schön und häßlich aus den Angeln: "Fair is foul, and foul is fair (1.1.12). Die Hexen in Macbeth sind Grenzwesen, die der Grenze zugleich ihre ordnende und unterscheidende Kraft rauben.
