DIFFERENT TYPES OF INTEGRATION, AN ANSWER TO SNAPPER

Snapper's article constitutes a considerable enrichment of the theory of integration. The difference between voluntary co-operation ofsovereign entities and unification imposed by war is essential.

My first attempt at a theory of integration, the impact of language difference, will, I hope, be followed by the introduction of other explanatory factors.
