In that case, it is inferred that conjunction with an obstructing substance arrests another cause of sound, which has become a trace; and because of its arrest, the series of sounds is not produced. When it is not produced, there is a cessation of hearing, just as, when the trace that is the cause of motion of an arrow is arrested by conjunction with an obstructing substance, there is an absence of motion. And there is the cessation of the series of vibrations graspable by the sense organ of touch. Contact of the hand on bronze vessels and the like is the mark of the series of traces. Therefore, another cause that has become a trace is not unapprehended. (36)
