Cardinal Henry Newman, writing about his religious conversion, autobiographically describes the state of mind that led me to agnosticism in virtually all things secular (especially politics and anything I read in the press) except those I see with my own eyes and touch with my own hands:
I could not continue in this state, either in the light of duty or of reason. My difficulty was this: I had been deceived greatly once; how could I be sure that I was not deceived a second time? I then thought myself right; how was I to be certain that I was right now? How many years had I thought myself sure of what I now rejected?
Apologia pro Vita Sua.
