“…Ralph Jessop's article explores how the prominent Common Sense theorists Thomas Carlyle (1795Á1881) and Sir William Hamilton (1788Á1856) countered the alleged melancholy affects from mechanical theories of mind. 36 The scope of this piece also looks forward to the thought of William James (1842Á1910) who, as Jessop argues, appealed to the earlier thought of Carlyle and Hamilton in his opposition to medical materialist psychology. Jessop shows how the thought of these significant, yet often marginalised, theorists of the Scottish School of Common Sense is best understood through Jü rgen Habermas's distinction between communicative and instrumental rationality.…”
