You're bringing up the other extreme (postmodernism), which I wouldn't agree with either. I'm arguing against certainty. We are stumbling along trying to communicate information as accurately as we can in order to produce predicted outcomes we deem desirable. Hopefully the evidence on an issue becomes so overwhelming that we can broadly reach a reasonable consensus. However, that consensus is subjective and dynamic. There is no objective process that will perfectly delineate "fact" from "fiction" as our Google News overlords would have you believe.
