The Made And The Made-Up, Steven L. Winter Walter S. Gibbs Distinguished Professor Of Constitutional Law

Law Faculty Research Publications

Truth is an ethical relation. Facts, whether descriptions of the physical world or of historical events, are necessarily mediated by our frames of reference. This contingency opens a space for disagreement that cannot be adjudicated by an absolute standard of truth. For those seeking power or profit, the temptation to exploit this state of undecidability is strong. When many question the institutions that broker meaning – science, the professions, the media – rumors, misinformation, deliberate distortions and falsehoods all proliferate. In the digital age, the ‘made’ is swiftly supplanted by the made-up. The remedy for this predicament is not technological …
