This paper is divided into two parts. The first focuses on inserting the ideal-type into the context of Weber’s conception of social reality and methodology. Weber’s conception of the ideal-type is compared with Durkheim’s conception of the social type. The second part of the paper is devoted to Weber’s ideal-type as a methodological construct. It relies on a general definition of the ideal-type and also on a conception of different kinds of the ideal-type: the historical (genetic) ideal-type, the general sociological ideal-type, and the ideal-type of social action. Attention is paid to differences and similarities between these different kinds of the ideal-type. Finally, two applications of the ideal-type are given.
