The paper deals with the problem of particularity of humanities, especially of social sciences. For that reason two types of humanities (humanities sensu largo) are distinguished: humanities sensu stricto (e.g. history) and social sciences (e.g. sociology or psychology). The application of concepts and methods of natural sciences to social sciences have been acclaimed by some philosophers and methodologists. This model neglects the particularity of social sciences. The author confronts this model with two other ones: Polish sociologist Stanislaw Ossowski's and Karl Popper's model of social sciences. As a result of the analysis the conclusion is reached: contemporary social sciences are irreducible to the concepts and methods of natural sciences.
