Maybe there is a difference between an idea and a concept. I have an idea of a cloud. I have no strong concept of a cloud, and that would not matter unless faced with a problem that required a strong concept of a cloud in order to resolve the problem.

Is there a problem? Seems to me if there were an actual and important problem whose solution were dependent on "what a cloud is" then you would have no shortage of conceptualizations. What then matters is to what extent they are useful for resolving problems.

I believe this is quite normal and our conceptualizations of ideas change as the problems we face change. For instance, you can always ask what does Justice, the Idea, mean. People have developed concepts over time and applied them. The success leads to further problems, asking again what Justice means, and further concepts.
