Quotes
Philosophy should never have been purified. Rather than being seen as a problem, “dirty hands” should have been understood as the native condition of philosophic thought--present everywhere, often interstitial, essentially interdisciplinary and transdisciplinary in nature. Philosophy is a mangle. The philosopher’s hands were never clean and were never meant to be.
-- Robert Frodeman and Adam Briggle, "When Philosophy Lost Its Way," New York Times, January 11, 2016
Origin
Interstitial derives from the Latin interstitium meaning "interstice" or "an intervening space." It entered English in the mid-1600s.
