The paper offers an analysis of Plato's conception of the care of the self in his 'Gorgias'. There are two components of the self-care: self-knowledge and self-control. The first part deals with self-knowledge. The second part asks the question, whether can be there a fixed model of the individual soul's order. The third part of the paper deals with Plato's conception of self-control. The last part is concerned with the problem of self-control training.
