The concept art of Kosuth tries to analyze the patterns of the intellect and explore the borders of art. The slight variations in the tones of the color of the letters and of the background, accompanied by the repetition of the motto Modus operandi, make this collection similar in many ways to a litany, chanted in muffled tones with subtile changes of voice that seem to have neither a beginning or nor an end.
The same ornamental motif also decorates the espresso version.
