The Specialization of Sensibility in Raw Material State into Stabilized Pictorial Sensibility, Le Vide

"The object of this endeavor: to create, establish, and present to the public a palpable pictorial state in the limits of a picture gallery.

This invisible pictorial state within the gallery space should be so present and endowed with autonomous life that it should literally be what has hitherto been regarded as the best overall definition of painting: radiance.
