Seneca, Ethics, and the Body: The Treatment of Cruelty in Medieval Thought

In an impassioned article written in 1941 Lucien Febvre urges the writing of a history of human sensibility and suggests in particular writing a history of cruelty. ¹ The general direction indicated by Febvre has been followed, but as far as cruelty is concerned his plea is still as relevant today as it was five decades ago. And since cruelty is one of the attributes commonly associated with the Middle Ages, ² it is particularly interesting to examine what and how medieval thinkers wrote on the subject.

An examination of sources dealing with cruelty from late antiquity to the early modern period yields surprising results. Whereas the writings of the thinkers of late classical antiquity and of the early modern period do include discussions of the issue, the writings of medieval thinkers before the thirteenth century contain only brief remarks. The first and only exception until the end of the Middle Ages is a short question on cruelty in Thomas Aquinas’s Summa theologiae. Other types of medieval sources, such as legal texts, chronicles, and literary texts, reveal the same scarcity of references to the subject during most of the Middle Ages. Thus this period seems to represent a gap between antiquity and the early modern period, with a reawakening of interest in the issue of cruelty towards the end of the Middle Ages.

The relative silence of medieval sources calls for identifying the factors which affected the treatment of cruelty by medieval thinkers. What are the reasons for the neglect of the subject as well as for the late revival of interest in it? And when the issue is discussed, what factors shape the discussion? Two issues seem crucial to me in answering these questions: the conception of the relation between body and soul and the relative weight given to actions vs. intentions in the dominant ethical framework. A third issue, of equal importance, provides a focus for the investigation of the treatment of cruelty in the Middle Ages and the factors affecting it; and this is the reception of Seneca. As interest in Seneca’s writings grew, so did the preoccupation with cruelty. There is a close thematic interaction between these two processes, beyond the chrono-logical coincidence.

Most obviously, discussions of cruelty as a subject per se referred explicitly to Seneca’s writings on the subject. Less directly, when cruelty was treated only in passing in the context of the Christian tradition, the manner in which the subject was addressed reflected a lack of Senecan influence, so that Seneca’s influence was felt through its absence. Nevertheless, the Christian tradition continued to influence references to cruelty even after the revival of Senecan influence during the high Middle Ages and to a certain degree even served as a filter, determining which aspects of Seneca’s writings on cruelty were used.

Thomas Aquinas and Seneca

The first medieval discussion of cruelty as a subject per se is the question De crudelitate (2-2-159) in the section on temperance in Thomas Aquinas’s Summa theologiae. Aquinas bases his discussion almost exclusively on classical sources, primarily Seneca’s De clementia. ³ Seneca referred to cruelty in detail both in this work and in another moral essay, De ira. His De clementia was written at the beginning of Nero’s reign, and it is addressed to the young emperor, his former pupil. Its stated aim is to praise Nero for possessing the quality of clementia, and to show how important this quality is for rulers. ⁴ The concept of clementia describes a quality of political men, the term having acquired political significance since the times of Caesar and Augustus. ⁵

De clementia was written before most of the actions which earned Nero his reputation were perpetrated; the only concrete action which may have inspired Seneca to write it was the murder of Britannicus, of which Nero was suspected. Regardless, the emperors preceding Nero were certainly not renowned for their clemency. Suetonius tells that one of Caligula’s amusements was to attend sessions of torture and execution; that he insisted on slow...
