A society which rests upon the supremacy of some factor over another irrespective of its rational or proportionate claims leads thought astray. (Source: Democracy and Education By John Dewey)
What does (the phrase) mean? Does it mean "the supremacy of some factor over another factor that is not rational"? If so, it is a good thing isn't it the supremacy of some factor over some irrational factor? AND how does a good thing lead thought astray? Could you help me clarify it? Thanks.
