"from Christ, to this king, to this burgher, to his maid, to her red shawl, to the color red, to the process of seeing the color red"

Robert Irwin, Who's Afraid of Red, Yellow, and Blue?, 2007–8.

The line belongs to Lawrence Weschler, writing in The Believer about an improbable debate between Robert Irwin and David Hockney that has taken place entirely through his writing. (Improbable, but not unbelievable: Weschler has just published two books totaling 30 years of interviews with the former artist and 25 years of interviews with the latter.)

A nice line, anyway! I believe we are now at "to determining who is permitted to do the seeing."
