An improving reputation

Seneca remains one of the few popular Roman philosophers from the period. He appears not only in Dante, but also in Chaucer and to a large degree in Petrarch, who adopted his style in his own essays and who quotes him more than any other authority except Virgil. In the Renaissance, printed editions and translations of his works became common, including an edition by Erasmus and a commentary by John Calvin. John of Salisbury, Erasmus and others celebrated his works. French essayist Montaigne, who gave a spirited defense of Seneca and Plutarch in his Essays, was himself considered by Pasquier a "French Seneca". Similarly, Thomas Fuller praised Joseph Hall as "our English Seneca". Many who considered his ideas not particularly original still argued that he was important in making the Greek philosophers presentable and intelligible. His suicide has also been a popular subject in art, from Jacques-Louis David 's 1773 painting The Death of Seneca to the 1951 film Quo Vadis.

Even with the admiration of an earlier group of intellectual stalwarts, Seneca has never been without his detractors. In his own time, he was accused of hypocrisy or, at least, a less than "Stoic" lifestyle. While banished to Corsica, he wrote a plea for restoration rather incompatible with his advocacy of a simple life and the acceptance of fate. In his Apocolocyntosis he ridiculed the behaviors and policies of Claudius, and flattered Nero—such as proclaiming that Nero would live longer and be wiser than the legendary Nestor. The claims of Publius Suillius Rufus that Seneca acquired some "three hundred million sesterces " through Nero's favor are highly partisan, but they reflect the reality that Seneca was both powerful and wealthy. Robin Campbell, a translator of Seneca's letters, writes that the "stock criticism of Seneca right down the centuries...the apparent contrast between his philosophical teachings and his practice."

In 1562 Gerolamo Cardano wrote an apology praising Nero in his Encomium Neronis, printed in Basel. This was likely intended as a mock encomium, inverting the portrayal of Nero and Seneca that appears in Tacitus. In this work Cardano portrayed Seneca as a crook of the worst kind, an empty rhetorician who was only thinking to grab money and power, after having poisoned the mind of the young emperor. Cardano stated that Seneca well deserved death.

Among the historians who have sought to reappraise Seneca is the scholar Anna Lydia Motto, who in 1966 argued that the negative image has been based almost entirely on Suillius's account, while many others who might have lauded him have been lost.

"We are therefore left with no contemporary record of Seneca's life, save for the desperate opinion of Publius Suillius. Think of the barren image we should have of Socrates, had the works of Plato and Xenophon not come down to us and were we wholly dependent upon Aristophanes ' description of this Athenian philosopher. To be sure, we should have a highly distorted, misconstrued view. Such is the view left to us of Seneca, if we were to rely upon Suillius alone."

More recent work is changing the dominant perception of Seneca as a mere conduit for pre-existing ideas, showing originality in Seneca's contribution to the history of ideas. Examination of Seneca's life and thought in relation to contemporary education and to the psychology of emotions is revealing the relevance of his thought. For example, Martha Nussbaum in her discussion of desire and emotion includes Seneca among the Stoics who offered important insights and perspectives on emotions and their role in our lives. Specifically devoting a chapter to his treatment of anger and its management, she shows Seneca's appreciation of the damaging role of uncontrolled anger, and its pathological connections. Nussbaum later extended her examination to Seneca's contribution to political philosophy showing considerable subtlety and richness in his thoughts about politics, education, and notions of global citizenship—and finding a basis for reform-minded education in Seneca's ideas she used to propose a mode of modern education that avoids both narrow traditionalism and total rejection of tradition. Elsewhere Seneca has been noted as the first great Western thinker on the complex nature and role of gratitude in human relationships.
