This cross-disciplinary symposium on Friedrich Kratochwil's The Status of Law in International Society engages with the interconnections between social knowledge (theory) and action (practice). Each contributor reflects critically on one of Kratochwil's nine meditations. These co-meditations cover not only Kratochwil's work, but they deepen discussions on the role of legal norms in international society, the practice turn, pragmatism, the production of knowledge, and human action. Kratochwil's reply to his co-meditators pushes the limits of prevailing thought on praxis. As a whole, the symposium exemplifies how we find ourselves always in the midst of theory and practice.

Kratochwil's diagnostic approach identifies specific failures in particular, historical contexts in order to prescribe practically realisable remedies under non-ideal conditions. The diagnostic approach compares actual alternatives against each other rather than against some ideal. Yet, the basis for such an identification is unclear. By reinterpreting Kratochwil's approach with the help of Buddha's Four Noble Truths, one can understand Kratochwil's existential worldview and his aims, but the medium Kratochwil uses hinders the attainment of those goals. He tries to communicate in writing something (phronesis) that belongs in the world of experience.

This foreword frames the Symposium in two ways. It summarises the core themes running through the nine ‘meditations’ in The Status of Law in World Society. Moreover, it places these themes in the wider context of Kratochwil's critical engagement with how we pursue knowledge of and in the social world and translate this knowledge into action. Ultimately, also his pragmatic approach cannot escape the tensions between theory and practice. Instead, we are in the midst of both.

Since its popular appearance in 2001, the responsibility to protect has gained wide attention. Yet, the meaning of responsibility in the R2P report has remained unexamined. The first task of this article is to conceptualise responsibility as it seems to arise from the R2P report. It is argued that the responsibility in the report is collective in nature, and analogous to obligations erga omnes and collective responsibility to extinguish fires before the institutionalisation of fire departments. The second task is to provide a model of collective responsibility with criteria that allow dividing the burden of fulfilling the common responsibility among the members of the collective. The model bridges the conceptual level with the level of practice.
