The problem of conditions for the possibility of human development is relevant both in philosophy and psychology. The purpose of the research is to combine psychological and philosophical discourses in order to solve the problem of conditions of the possibility of personal transformation in the process of personal development. The study uses a conceptual analysis and synthesis of ideas from philosophy and psychology in relation to the problem of personal development. The philosophical basis of the research is philosophy of transgression, philosophy of unconscious and philosophy of authenticity of human existence. The psychological basis is the approaches of L. S. Vygotsky, J. Piaget and J. Kelly's approach to the problem of mental development. The author adheres to a philosophical and anthropological approach to human existence (considers the existence of man from within himself). The article presents the definition of human development as a process of transition of potential capabilities into actual ones; it is shown that the condition for man’s development is contact with his unconscious. The concept of metanoia (change of consciousness) is revealed as the main event of transgression, the transition of a person to a new stage of development. The role of the “bestial” origin in the process of transgression is demonstrated. The role of transgression in the process of a person's gaining authenticity of existence necessary for personal development is described. Based on the interdisciplinary points of support discovered by the author, it is concluded that a successful conceptual synthesis of philosophical and psychological approaches to the problem of human development is possible, which requires productive cooperation between psychologists and philosophers.
