Question: Kairosis was a term derived from a usage by which British literary critic?
Context: Catherine Belsey (born 1940) is a British literary critic and academic.  She chaired the Centre for Critical and Cultural Theory at Cardiff University (1988-2003) before moving to Swansea University (2006–14).  Her book "Critical Practice" (1980) was an influential poststructuralist text in suggesting new directions for literary studies.  She is currently Visiting Professor of English at the University of Derby and Fellow of the English Association and Fellow of the Learned Society of Wales.  She has consistently aligned herself with international innovations in the theory and practice of criticism. Ian Robinson (born 1937) is a British literary critic and English professor.  He was educated at King Edward VI Grammar School, Retford, and Downing College, Cambridge (he earned firsts in both parts of the English Tripos) where he was a pupil of F. R. Leavis.  Robinson served as lecturer and senior lecturer in the English Department at University College of Swansea from 1961 to 1997 Best known for his 1973 book "The Survival of English", Robinson has been a champion of traditional English literature and a critic of what he alleges to be the degeneration of the English language across all departments of modern life.  With David Sims, he co-founded The Brynmill Press Ltd, in 1970, a company devoted to serious criticism which began with the quarterly review "The Human World" (1970–4) and went on to publish works of literary criticism, philosophy (including Ludwig Wittgenstein’s "Remarks on Frazer’s “Golden Bough”") fiction and poetry. Sir John Frank Kermode, FBA (29 November 1919 – 17 August 2010) was a British literary critic best known for his work "", published in 1967 (revised 2000), and for his extensive book-reviewing and editing. Paul Antony Tanner (18 March 1935 – 5 December 1998), was a British literary critic of the mid-20th century, and a pioneering figure in the study of American literature.  He was a fellow of King's College, Cambridge, where he taught and studied for 38 years, from 1960 until his death in 1998. John Bernard Beer, FBA (born 31 March 1926) is a British literary critic.  He is Emeritus Professor of English Literature at the University of Cambridge and a Fellow of Peterhouse, Cambridge.  Best known as a scholar and critic of Romantic poets – especially William Blake, Samuel Taylor Coleridge, and William Wordsworth – he has also published on E. M. Forster.  He was elected a Fellow of the British Academy in 1994. Adat (Jawi: عادت) is the generic term derived from Arabic language for describing a variety of local customary practices and tradition as observed by Muslim communities in North Caucasus, Central Asia and Southeast Asia.  Despite its Arabic origin, the term adat resonates deeply throughout the Maritime Southeast Asia, where due to colonial influence, its usage has been systematically institutionalised into various non-Muslim communities.  Within the region, the term refers, in a broader sense, to the customary norms, rules, interdictions, and injunctions that guide individual's conduct as a member of the community and the sanctions and forms of address by which these norms and rules, are upheld.  Adat also include the set of local and traditional laws and dispute resolution systems by which society was regulated. Kairosis is the literary effect of fulfillment in time.  This effect is normally associated with the epic/novel genre of literature, and can be understood by the analogy "as "catharsis" is to the dramatic, so "kenosis" is to the lyric, so "kairosis" is to the epic/novel."  It is derived from Kermode's usage of kairos in literary aesthetics, and is part of an ongoing debate within literary aesthetics about the limitations of the rhetorical use of the term kairos. John Ferrar Holms (1897–1934) was a British literary critic. The Criterion was a British literary magazine published from October 1922 to January 1939.  "The Criterion" (or the "Criterion") was, for most of its run, a quarterly journal, although for a period in 1927-28 it was published monthly.  It was created by the poet, dramatist, and literary critic T. S. Eliot who served as its editor for its entire run. Ex tunc is a legal term derived from Latin, and means "from the outset".  It can be contrasted with "ex nunc", which means "from now on".  An example of usage of the term can be found in contract law, where avoidance of a contract can lead to it either being void "ex nunc", i.e. from then on, or "ex tunc", in which case it is treated as though it had never come into existence.
