 According to Katz, Stace does not notice the difference between experience and interpretation, but fails to notice the epistemological issues involved in recognizing such experiences as "mystical," and the even more fundamental issue of which conceptual framework precedes and shapes these experiences.Katz further notes that Stace supposes that similarities in descriptive language also implies a similarity in experience, an assumption which Katz rejects.According to Katz, close examination of the descriptions and their contexts reveals that those experiences are not identical.
