Widmer sheds light on a neglected aspect of the Western philosophical tradition. Following an era of Hegelianism, the members of the neo-Kantian "Marburg School," such as Friedrich Albert Lange, Hermann Cohen, Rudolf Stammler, Paul Natorp, and Ernst Cassirer defended socialism or left-wing ideals on Kantian principles. In doing so, Widmer breaks with two mistaken assumptions. First, Widmer demonstrates that the left-Hegelian and Marxist traditions were not the only significant philosophical sources of socialist critique in nineteenth-century Germany, as the left-Kantians identified (...) problems of normativity that the left-Hegelians could not adequately address. Second, Widmer challenges the prevailing assumption that the political philosophies developed in the Marburg School can be comprehensively characterized as a unified school of "ethical socialism." By showing that they varied fundamentally regarding their political views and their philosophical foundations of socialism, Widmer fills a gap in the studies of neo-Kantianism that is long overdue.

Neutral monism is the view that both ‘mind’ and ‘matter’ are grounded in a more fundamental form of reality that is intrinsically neither mental nor material. It has often been treated as an odd fringe theory deserving of at most a footnote in the broader philosophical debates. Yet such attitudes do a grave disservice to its sophistications and significance for late nineteenth and early twentieth-century philosophy of mind and psychology. This paper sheds light on this neglected view by situating it (...) within broader historical monist debates about the mind and bringing attention to one of its central internal disputes regarding ‘mental chemistry’. By taking a closer look at how Ernst Mach, William James, and Bertrand Russell address the question of whether and how our mental episodes are composed of more basic elements, it highlights deep differences among their conceptions of the fundamental ‘neutral stuff’ and its relations to ‘mind’ and ‘matter’.
