Again, in pursuit of maximum simplicity and logic, LeWitt adopted the idea of using elementary mathematical progressions, or series, as the basis of his work. In particular this had the advantage, for him, of eliminating any residual personal or subjective elements of expression in the work: the artist 'would follow his predetermined premise to its conclusion avoiding subjectivity. Chance, taste, or unconsciously remembered forms would play no part in the outcome. The serial artist does not attempt to produce a beautiful or mysterious object but functions merely as a clerk cataloging [sic] the results of his premise'. This attitude eventually led LeWitt to his wall drawings where the responsibility for carrying out the procedures laid down by the artist is handed over to the owner of the work.
