“What I mean by ‘line’ is exactly that: a single mark, short or long, drawn with a pen, pencil, stylus, or any sharply pointed instrument that is held in the hand and commanded by it, in coordination with the brain, to inscribe on paper, tablet, plate, or any chosen surface exactly that mark and not another.
This last qualification is important. When rubbing a piece of charcoal, pastel, or blunt pencil on a surface, one accepts (even hopes for) a certain degree of approximation, even of accident. The resulting tone is, from an analytical point of view, vague, when compared with line. Line is precise and unequivocal. It is here, not there. Making a line is not about accidents.”—LEBBEUS WOODS (via drawingarchitecture)
