We call actions right and wrong, teachers wise and ignorant, and pictures elegant and grotesque. Philosophers place evaluative concepts into two camps. Thin concepts, such as goodness and badness, have evaluative content, but they supposedly have no or hardly any nonevaluative, descriptive content. In contrast, thick concepts such as kindness, elegance and wisdom supposedly give a more specific idea of people or things. Yet, given typical linguistic conventions, thick concepts also convey evaluation. Kind people are often viewed positively whilst ignorance has negative connotations.

In this full-length study, Simon Kirchin discusses thin and thick concepts, highlighting key assumptions, questions and arguments, many of which have gone unnoticed. Kirchin focuses in on the debate between ‘separationists’ (those who think that thick concepts can be separated into component parts of evaluative, often very ‘thin’, content and nonevaluative content) and ‘nonseparationists’ (who deny this).
