A discussion of the emergence of a modern Jewish collective consciousness in Eastern Europe does not require us to address the question of the beginnings of a movement, which also has an organizational aspect. The phenomenon under discussion—at least in its initial stage—was not organized; there were no membership cards, bylaws, or party conferences. It is my contention, however, that the emergence of a Jewish nationalist movement was connected to, and dependent upon, the prior emergence of a collective consciousness.Thus, on the one hand, our discussion is not based upon the phenomenological definition of nationalism, which is not a simple matter, while, on the other hand, we view the institutionalized nationalist movement as a consequence of a process of consciousness-building. Mine is a syncretic approach, the advantage of which is that it does not observe a historical process from an intellectual or theoretical point of reference foreign to the process.
