The article aims to present briefly the problem of a theoretical nature, namely, the division of agency and structure in sociology. A general review of the problem of agency is presented. The authoress is confined to minimum details of classical meta-theory in order to present two theoretical notions of Margaret Archer and Anthony Giddens. The structure of the paper is as follows: firstly, the theoretical problem of 'agency theory' in sociology is presented, secondly, differences between structuration theory and the morphogenetic approach are shown, and lastly, the importance of the reintegration of agency - structure dualism - is presented.
