Ten Years of Idiographic Science 

The first volume of the Yearbook of Idiographic Science (YIS) was published on 2009. In a nutshell, the idea at the grounds of the YIS project is that idiography and nomothetic are not juxtaposed logics and that the science cannot but be both nomothetic – in the aim – and idiographic – in the modes. About thirteen years later, the sense and the direction of the YIS project envisaged in the first volume’s introduction – together with the difficulties to pursue it – are still alive and valid. Thus, to both celebrate the milestone of the tenth issue and to plan the future, we asked to some colleagues, almost all contributors of previous volumes, to discuss what idiographic science means today, and what can mean tomorrow.The works they have generously provided are very instructive – each of them pictures a peculiar perspective on idiography that enables to recognize old and new challenges, thus paving the way to innovative ideas and directions.
