What is the shape of institutions? Materializing the cycles of life in an East African age class society.

Giving a precise definition of what an institution is raises epistemological dilemmas concerning its supposed universal applicability and the coexistence of different institutional regimes (e.g. state and customary). Scholars who have dabbled with this question often identify rules, behaviours, values, or social roles as the essence of institutions. In fact, these constitutive features do not necessarily occupy a leading position in all societies. In this article, I argue that, among East African pastoral populations such as the Samburu of northern Kenya, institutions of age class systems are the product of the changing identities of the person's maturation process. These institutionalized life cycles regulate the distribution of powers, rights, and duties within the community. Moreover, if institutions can be different 'things', similarly, the objects through which they materialize can vary profoundly from one social system to another. In the case of the Samburu, customary age institutions can be perceived, performed, and manipulated in the form of songs, dances, and ornaments that represent their tangible, aural, visible, and actionable substance. Just as age manifests itself through the body, institutions founded on age take shape through sonic and kinetic bodily expressions. [ABSTRACT FROM AUTHOR]
