This thesis aims to provide an analysis of comparative ideologies through close reading of 19th-century fictional texts and their 20th-/21st-century film and television adaptations, isolating similarities and differences in the presentation of specific socio-political issues. The fictional texts in question have been chosen for their display of a complex and substantial dialogue with the writings of the 19th-century political and cultural commentator Thomas Carlyle, a dialogue whose existence is established through documentary evidence and close reading of the texts themselves. By extending the analysis of these texts to their later screen adaptations, Carlyle’s ideas become a background against which changing assumptions about the human condition and changing modes of narrativizing said condition come into relief. The suitability of Carlyle for such a study is demonstrated by an examination of his reception history, which establishes him both as a virtually ubiquitous influence on the Anglophone literature of his day and as a near perfect ideological Other for a 21st-century reader in Western culture, articulating stances at odds with ideological tendencies within contemporary culture and embodied in dominant generic tropes of contemporary narrative. Relevant adaptations are considered as a form of reading Carlyle, one whose elements of debate and struggle with the ideological otherness of the text is explored using Gillian Beer’s concept of ‘arguing with the past’. The importance of a re-consideration of Carlyle’s ideas within the context of 21st-century narratives and cultural assumptions is argued using Paul Feyerabend’s conception of knowledge as ‘an ever increasing ocean of mutually incompatible alternatives’, wherein even failed views must be retained and re-worked to add to the content of the whole.
