In many of the cases of conceptual innovation, … creating the conceptual tools is a precondition to coming to a clear understanding of what the problem was in the first place. It is very difficult to describe the transition after it has taken place because it is difficult for us to put ourselves back into the situation of confusion, indeterminacy, and perplexity that existed before the new tool brought clarity and this means it is difficult for us to retain a vivid sense of what a difference having the concept made. We can just barely imagine ourselves in a world in which there are no states, as opposed to local barons, warlords, clans, primitive communal forms of village organisation, etc.
