The most important work of the largest American philosopher of the XX century Wilfrid Sellars. It was first published in the form of an essay in 1956 and led to a dramatic change in analytical philosophy, cutting off that connection - in the form of the doctrine of "knowledge by acquaintance" - which united Bertrand Russell and Alfred Ayer with John Locke and David Hume. Sellars' criticism of Dunn's myth in this work caused analytical philosophy to move away from the fundamentalist orientation of logical empiricism and questioned the very idea of ​ ​ epistemology.
