The concept of will is one of the most common in modern humanities and social sciences. At the same time, its use has still serious problems of clarification and operationalization content. The will discourse is considered in this work on the basis of modern political science and neuropsychology. This allows us to systematize the main components of the will thematization, and also to trace important consequences of such systematization for the methodology of science, justice and morality. The main conclusion is the compatibility of causal determination and free will. This compatibilism is based on the fundamental role of responsibility, which is provided by socio-cultural practices. Socialization removes the personality from the natural cause-and-effect relationships, closes them to a person, turning it into a causa sui - through education, punishments and rewards. Consciousness and freedom are the epiphenomena of culture. The primary factor is responsibility. Thus, the dispositional nature of motivation gets a neurophysiological fixation. In conclusion, it is stressed that the interdisciplinary nature of the will is an example for the narrative correlation of sciences and humanities explanations.
