¶The first work, ESTC T148954; Edinburgh, Manchester & Newcastle only in the UK. 'In the tradition of eighteenth-century moralism, Cogan offers his philosophical analysis in the service of a practical concern with human motivation to virtue and vice. An accurate analysis of the passions and affections "is to the Moralist", he suggests, "as the science of Anatomy is to the surgeon" (p.vi). Unlike many of his predecessors, however, Cogan sharply separates psychological from ethical analysis, devoting the "Philosophical Treatise" exclusively to discourse on the nature and classification of the passions, emotions and affections and to observations regarding their causes, inter-relations and effects.' (Wozniak, R.H. Dictionary of Eighteenth-Century British Philosophers.) A second volume of 'An Ethical Treatise on the Passions' was published in 1810.
