Abstract

Alphonse Guillebert (1792-1861), pastor, teacher and politician, was one of the leading figures of the Academy of Neuchâtel, founded in 1838 and opened to students in the autumn of 1840. In this article, we will first offer a brief biography, then indications on the various facets of the written work of our author. We have used only a part of the available sources and we are therefore aware that further study would be worthwhile. In the following, we describe the philosophy course of Guillebert, and finally we look at an essay – the Dissertation sur l’unité en philosophie – in which he was more personal than in his teaching. Marked by the French intellectual climate of the first half of the nineteenth century, our author was able, by opening himself to Germany, to introduce his listeners to the main philosophical doctrines of his time.
