This article posits a number of theoretical pointers towards a conceptual clarification of the concept of non-violence, in particular in relation to notions of conflict, pact, mediation, compromise, strength, benevolence, and truth. It sets them against the concept of violence and the behaviours which are associated with it, and is based on the thought of M. K. Gandhi and E. Weil. Finally it presents some pointers towards a strategy for non-violence and explains the sense of the principle of non-cooperation.
