I often invoke and paraphrase some very specific historical sources that speak to my views on the topic in a deeper way.
Namely the first (by him) Dada manifesto by Tristan Tzara and Berlin Dada by Richard Huelsenbeck, both circa 1918, but oddly prescient, because the dialectic never changes.
Another good one is the one by Francis Picabia. The wording on that one is a more vitriolic condemnation of both seriousness and capitalism, in places, but it expresses much the same feelings, albeit without Huelsenbeck's eye for social justice and revolutionary activism.
