Abstract

This article clarifies Gottfried Wilhelm Leibniz’s understanding of toleration, a topic that has become controversial in the last few decades. For the purpose of brevity and exactness, only his writings and letters dating from the beginning of his philosophical thought (1668 to 1676) are analysed, while the main focus is on Leibniz’s understanding of political toleration, or the relation of the state towards the existence of confessions (i.e., churches or denominations) different than the ruler’s. The article investigates the understanding of toleration in the 17th-century Holy Roman Empire, which turns out to be the sufferance of difference rather than its affirmation or celebration, as well as the historical context of tolerating different confessions in various states of the 17th-century Empire. While indirect evidence is shown that Leibniz favoured toleration in confessionally mixed German states, the main point of the article is that young Leibniz cannot be counted among the proponents of toleration only if his vision of politically and ecclesiastically united Empire didn’t tolerate further existence of differing confessions. Based on the analysis of the memorandum Securitas Publica from 1670, it is conclusively shown that Leibniz was in favour of toleration of differing confessions even in the united Empire that he envisioned. The last part of the article explains Leibniz’s attitude towards “atheism” on the cases of celebrated philosophers which were widely perceived as atheists in the learned world of the time, namely Thomas Hobbes and Baruch Spinoza. It is concluded that the relation of young Leibniz to them and their work cannot be characterized as intolerant or censorious.
