For Seneca, the firmness of the Wise is shown in his ability to remain calm against attacks, as he explains in his treatise of that name. Attacks can come in the form of injustice, iniuria, and disparagement, contumelia; Seneca proves that neither of them affects the wise man. Contumelia is linked to contemptus in definition and conceptualization so that the remarks on how to deal with disparagement contain clues as to what contemptus means for Seneca. The article argues that Seneca understands the term in a double sense: First, contemptus denotes a reprehensible attitude. Second, it designates a kind of indifference which is to be understood in the context of Stoic apatheia.
