Wills have many functions in the process of cognition. Among them there are three elementary functions: functions of direction

control and regulation. The active functions of wills in the process of cognition emerge and develop in the course of practice. The changes of wills aren’t absolutely in step with the changes of their external social and cultural environments. The wills have their own relative independence. It is of great necessity to make deep studies of the functions of wills in the process of cognition.
