The Res Cogitans EP is a two-track 10-inch by Felix K, released on Hidden Hawaii (cat. Hidden Hawaii Ltd. 006). It pairs the title track "Res Cogitans" with "11 Block Girl," both of which later reappeared on the 2018 compilation Archive #1. Hard Wax described it as "excellent dub techno / leftfield drum & bass hybrids." Its title (Latin for "thinking thing," from Descartes) pairs it with the companion Res Extensa EP.
