Currently, there are a s number of positions on periodization and stages of the evolutionary development of pragmatism. In contemporary philosophy and the history of philosophy there is no stable consensus as to who of the modern philosophers can be unambiguously ranked among pragmatists and neo-pragmatists, and also, from what point can one speak of the onset of the neo-pragmatist stage of development of this tradition. The lack of a unified approach, ultimately, makes it difficult to understand the content of pragmatism itself as a philosophical position due to the impossibility of linking to it any key figures and prominent researchers. The article discusses the main provisions and approaches to the periodization of the stages of the evolution of pragmatism, adopted in the scientific literature, and offers arguments in favor of some adjustments regarding the chronology of neo-pragmatism.
