To be understood.

'The progression of a painters work, as it travels in time from point to point, will be toward clarity. Toward the elimination of all obstacles between the painter and the idea, and between the idea and the observer. As examples of such obstacles, I give (among others) memory, history and geometry, which are swamps of generalisation and from [which] one might pull out parodies of ideas (which are ghosts) but never an idea itself. To Achieve this clarity is, inevitably, to be understood'

- Rothko, 1949.
