Journal of the History of Philosophy

The Hellenistic schools played a major role in the rise of modern philosophy during the sixteenth and seventeenth centuries. Stoicism was influential in the development of a secular ethics emancipated from theology, Epicureanism in the mechanical and corpuscular views of the new science, and Skepticism in the predominant role that epistemology assumed in modern philosophy. Bonacina shows that this influence continued to be considerable during the eighteenth and early nineteenth centuries. He examines the treatment of these three Hellenistic philosophies by a large number of (mostly German) historians of philosophy and by the main philosophers of the period. Among the historians, Bonacina detects a progressive drive towards historical objectivity. However, the religious interest in the assessment of the ancient schools is still noticeable until the early eighteenth century when it begins to be increasingly replaced by contemporary philosophical sympathies and affiliations. This interest is even stronger among the main philosophers of the period, who use the Hellenistic philosophies as weapons in the intellectual battles in which they were engaged. A brief summary of the main aspects of this use, first of Stoicism and Epicureanism, and then of Skepticism, by some of the major philosophers examined by Bonacina will illustrate this central point of the book.

Bayle continues Gassendi’s project of rehabilitating Epicurus. But his effort is not to make Epicureanism compatible with Christianity. He uses Epicurus’ philosophy to enhance his opposition to rational theology and Epicurus’ alleged virtuous life to corroborate his view that forced conversions cannot be justified by the need to make atheists or heretics good citizens. According to Bayle, Stoics—unlike Skeptics and Epicureans and like Catholic monks—are intolerant dogmatists, holding views incompatible with the true religion. A few years later, in the context of the French Enlightenment, the assessment of Stoicism and Epicureanism is still determined by antireligious controversy, but now revelation itself becomes the main target. Diderot, d’Holbach and La Mettrie all hold that a Stoic ethics which despises the passions is incompatible with human nature (just like Christian morals and contrary to Epicurean morals). Voltaire’s evaluation of Stoicism and Epicureanism strikes both his contemporary materialists and Christianity. Stoic deism is for Voltaire the alternative both to materialism and to revealed religion. Bonacina also shows that the Stoic/Epicurean opposition in ethics is an important weapon among the British moralists. While Shaftesbury finds in Stoicism [End Page 324] support for his view of innate moral feelings, Mandeville opposes him, attacking Stoicism and defending Epicureanism. Moving to the German context, Bonacina shows that Kant is often sympathetic towards Epicurus, in particular when the ancient philosopher is contrasted with modern ones. Epicurus’s materialism may have had only a phenomenal status and is more internally consistent than a modern materialism such as Locke’s, who accepts the existence of a nonmaterial God and soul. As to Stoic ethics, Kant claims that it is partially true—to the extent that virtue is not conditioned—and partially false, for the Stoics think of the summum bonum as empirically available whereas it is an ideal of practical reason. Hegel also uses Stoicism and Epicureanism for the vindication of his own philosophy and criticism of established ones. For instance, Stoic ethics is a step in the development of the Mind, but just like Kantian ethics it is empty, deprived of ethicity and therefore in need of being dialectically overcome.

Skepticism plays perhaps an even larger role in the philosophical debates of the period. Bayle takes the Skeptic standpoint (in opposition to the dogmatist in general and to the Stoic in particular) as the model for the historian of ideas who must objectively report the views and critically examine them without religious and philosophical preconceptions. Even more than Epicurus, Pyrrho is presented as a foe of rational theology and as indirectly showing the need of appealing to pure faith. Bonacina then examines the role played by Skepticism in the...
