Abstract

Building on the research of Manfred Kuehn, the author argues that, whatever influence the Scottish Common Sense Philosophy of Thomas Reid may have had on the development of Immanuel Kant’s refutation of idealism, it was filtered through the thinking of Kant’s largely forgotten German contemporary, Johann Nicolaus Tetens. While the importance of Tetens for understanding Kant is examined in connection with only one idea, the aim is to demonstrate that Tetens is a figure worthy of serious historical consideration.
