Skepticism seems to be the most appropriate means for illuminating a philosophical landscape shrouded in fog. The relatively restrained metaphor of “Aufklären” was used first by German philosophers to describe their project of removing prejudice and obscurity. British philosophers instead used the concept of “improvement,” and in France, the endeavours of the philosophes were largely associated with a determined fight against the dogmatic teachings of an all-powerful church and for religious and political freedom. But not every philosopher who employed skeptical arguments or the method of skepticism was therefore a skeptic, or someone who intended to establish a form of skepticism. And [End Page 171] some who sought to provide philosophy with a firm anti-skeptical foundation found themselves being accused of being skeptics themselves. Berkeley’s dogmatic Immaterialism was accused immediately of leading right away to the most abstruse kind of skepticism ever heard of, and Kant’s critical philosophy was forbidden in Hessia because of its alleged skepticism. Furthermore, many philosophers were indebted to some form of skepticism while not being skeptics themselves. Thus Reid’s common-sense-philosophy owed as much to Hume’s skeptical philosophy as did J. G. Hamann and F. H. Jacobi.Modern skepticism goes back to ancient Academic and Pyrrhonian Skepticism, which many philosophers of the Enlightenment for one reason or another still considered as a live option. But exactly what kind of skepticism their own writings entail and to what extent they were influenced by more modern types of skepticism—like that to be found in the works of Montaigne, Bayle, and others—is not always easy to decide. In addition, skepticism was sometimes viewed as a kind of systematic philosophy and the skeptic was considered to be a specific kind of philosopher, different from a Platonist, Stoic, or Epicurean, as in Hume for instance. But the vast majority of philosophers used skeptical arguments as instruments, or as the first step in laying the foundation for a new philosophical system. Finally, there are many much more subtle traces of skepticism in Enlightenment thought, which cannot always be put together easily in a comprehensive picture. The many-sided history of skepticism in the eighteenth century is accordingly difficult to tell.Richard H. Popkin’s work has been decisive for a further investigation of eighteenth century skepticism. His early “Scepticism in the Enlightenment” (1963) was seminal. Popkin pointed out in this article Hume’s central position. Hume marked the beginning of an increasing debate about different and variable types and contents of Enlightenment skepticism. Scepticism in the Enlightenment contains articles by Popkin himself, as well as articles by the late Giorgio Tonelli, known to many as an expert in Kant’s precritical philosophy, and by the late Ezequiel de Olaso, which were directly or indirectly occasioned by Popkin’s work. Only two of the ten articles are new (de Olaso on “Scepticism Old and New,” and Popkin’s very useful contribution on “Berkeley in the History of Scepticism”). But Tonelli’s “Kant and the Ancient Skeptics,” which appeared in 1967 in German, appears here for the first time in English translation. Although Tonelli’s scholarly article is still of interest today, Hume’s influence on Kant’s thought in the middle of the 1760’s should not be underestimated. Tonelli also seems to be too sceptical about Kant’s first-hand knowledge of ancient skepticism. For instance, Johann Matthias Gesner’s Chrestomathia Graeca (Leipzig, 1731), the school book used in the Greek class Kant attended as a...
