It has been established that philosophical thought has been divided into three main currents since ancient times. The ontological foundation of each of these currents has been emphasized. The necessity and timeliness of uniting these currents in a synthesizing doctrine have been substantiated. A path to synthesis has been indicated through the modernization of the doctrine of determinism by supplementing it with the theory of circular (circulatory) autodeterminism. The conclusion has been drawn regarding the relevance of studying the three worlds of human private existence and their interaction.
