The similarities between William James’ Stream of Consciousness and Henri Bergson’s La durée réelle have often been noted. Both emphasize the fundamentally temporal nature of our conscious experience and its constant flow. However, in this article, I argue that despite surface similarities between the OP theories, they are fundamentally different. The ultimate reason for the differences between the theories is that James believed that we should reject psychological explanations that depend on synthesis within the mental sphere. This is because such (...) explanations are incompatible with empiricism. Instead, we should look to the physiological mechanisms underpinning mental states. In contrast, Bergson was an adamant defender of a form of mental processing which he called qualitative synthesis. Duration itself, for Bergson, is a form of qualitative synthesis. However, in 1906, less than five years before James died, Bergson convinced him to change his mind. This results in a huge shift in James’ thought. Unless we understand how far apart James and Bergson were prior to this shift, we will not have a proper picture of the full influence of Bergson on James’ thought, nor of the major changes to James’ philosophy that occurred near the end of his life.

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’.
