The conception of time that dominates in the educational world of today is that of measurable, invested and managed chronological time. It is the conception of time that corresponds to current priorities such as performativity, global synchronization of educational systems, raising standards and meeting the challenges of the market. The educational transformation of the self and the world, however, requires another conception of time, one that frames another kind of thought and another meaning of education. This article discusses these two (...) conceptions of time by employing the distinction between chronos and kairos. The aim is not to turn this distinction into a dichotomy; instead, the aim is to recuperate the conception of time as kairos and connect it with a desire of philosophy and with education as a lifelong effort towards transformation rather than success. In a complex relation with chronosophy as time management, kairosophy is thus introduced as a critical reflection on lived time. (shrink)
