barrer1

nounbarrer (plural barrers)

plural barrers

  1. One who or that which bars.

    The worst merely bars some exceptions without looking at the proof at all. Hence the mystification when we have the proof on the one hand and the exceptions on the other. In the mind of such primitive exception-barrers, the proof and the exceptions exist in two completely separate compartments.
