Book excerpt: The fourth in a series that explores cultural and ethical values in Classical Antiquity, this volume examines the negative foils, the anti-values, against which positive value notions are conceptualized and calibrated in Classical Antiquity. Eighteen chapters address this theme from different perspectives –historical, literary, legal and philosophical. What makes someone into a prototypically ‘bad’ citizen? Or an abomination of a scholar? What is the relationship between ugliness and value? How do icons of sexual perversion, monstruous emperors and detestable habits function in philosophical and rhetorical prose? The book illuminates the many rhetorical manifestations of the concept of ‘badness’ in classical antiquity in a variety of domains.
