A work of art may be understood as a conductor from the artist's mind to the viewer's. But it may never reach the viewer, or it may never leave the artist's mind.
Sol LeWittA blind man can make art if what is in his mind can be passed to another mind in some tangible form.
Sol LeWitt[The artist's aim is] not to instruct the viewer, but to give him information... . 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 cataloguing the results of his premise.
