事实
For every expert there is an equal and opposite expert, but for every fact there is not necessarily an equal and opposite fact.
If facts, logic, and scientific procedures are all just arbitrarily "socially constructed" notions, then all that is left is consensus--more specifically peer consensus, the kind of consensus that matters to adolescents or to many among the intelligentsia.
Facts do not speak for themselves. They speak for or against competing theories. Facts divorced from theories or visions are mere isolated curiosities.
Mistakes can be corrected by those who pay attention to facts but dogmatism will not be corrected by those who are wedded to a vision.
