I went through something like this when I read Jaynes's PT:LOS. The object of my idolatry was the Bayesian approach to data analysis. I don't think it would be accurate to say I ever had antipathy towards it, but I know now it's not the panacea I originally took it for. To a lesser extent, I idolized Jaynes. Again, I never hated him or his ideas, but I now have a better idea of where he went wrong.
We all have heroes or idols, people we look up to and turn to, in one form or another, for guidance or wisdom. Over the years, I've noticed that my feelings towards those I've idolized tend to follow a predictable pattern. The following is the extraction of this pattern.
