The aim of the article is to introduce the concept of personality and character which is based on the activity theory approach by A.N. Leontiev. The introductory part of the work gives a short history of characterology whose analysis reveals apparent uncertainty in understanding the subject matters of character psychology and personality psychology. They are directly (character) or indirectly (personality) confined to a person’s psychic individuality. However, the specific content of this individuality appears to be so broad and various that characterology starts losing its clear contours while personality does not find any generally accepted definition. In the framework of the developed concept, personality is regarded as a structure of life meanings while character is seen as an instrumental level which accepts life meanings for performance and implements them in human actions. Nonidentity of the two studied formations is shown: they are different in terms of content, function in human psychics, units of structure, general construction and genesis. Some examples are given based on the data of ethnic psychology. They show how a sense formation which is the same for different nations is realized through unequal characterological techniques. On the other hand, a few sense formations can be expressed by a single action or stereotype. In conclusion problems of correlation between personality and character and the source of their generation are discussed.
