This article analyzes the philosophical foundations of the concept of nonlinearity and its significance in modern scientific knowledge. The manifestation of nonlinear processes in nature, society, and systems of thought is studied from a philosophical point of view. Based on the concepts of synergetics, the theory of complex systems, and self-organization, the theoretical and methodological aspects of nonlinearity are highlighted. The relationship between determinism and randomness, as well as the significance of linear and nonlinear determinism, are also analyzed. It has been revealed that the philosophy of nonlinearity manifests itself as a methodological basis combining linear determinism, synergetic dialectics, and indeterminism, and is a modern approach to the analysis of complex social processes. The research results serve to deepen the understanding of the philosophical content of the concept of nonlinearity and substantiate its scientific and theoretical significance.
