This issue concerns itself with "numbers," ranging from a brief note on "The Psychology of Number" by John Dewey and John McLellan, to Vincenzo Latronico's historical overview of the ongoing attempt to conjure "truths from thin air" (such as proof of the existence of god). In between are essays and articles by Cory Arcangel, Perrine Bailleux, Rosie Cooper, Dan Fox, Angie Keefer, Mathew Kneebone, James Langdon, Philip Ording, Katherine Pickard, David Reinfurt, and Justin Warsh, plus an indexical book review by the late David Foster Wallace.
