Answer:
Power and ideas.
Step-by-step explanation:
Most of Eric Wolf's work is based in power and ideas, this subjects he analyse them in the book ''Envisioning Power: Ideologies of Dominance and Crisis''.
He believed that all kind of relation ships are determined by power and the ideas beneath. For him, power could be seen as:
- Power inherent in an individual.
- Power as capacity of ego to impose one's will on alter.
- Power as control over the contexts in which people interact.
- Structural power.
The last one, he put it in relation ships, because that kind of power have certain structure, hierarchy, but without a clear dominance from each part.
