Letter 58 — On Being (§21)

“Do you ask me where the difference lies? The former is the pattern; while the latter is the shape taken from the pattern and embodied in the work. Our artist follows the one, but the other he creates. A statue has a certain external appearance; this external appearance of the statue is the “form.” And the pattern itself has a certain external appearance, by gazing upon which the sculptor has fashioned his statue; this is the “idea.” If you desire a further distinction, I will say that the “form” is in the artist’s work, the “idea” outside his work, and not only outside it, but prior to it.”
