@fresco,
YOU have to rise up from the empty words level where you usually well, to the level where you can account for reality, including the reality of babies, their fingers, and the dangers out there that threaten their fingers, doors, electricity sockets and hammers included. When a baby, unattended, sticks his finger in a door that slams, he is
hurt for real, whether he can verbalize it or not. Therefore language has nothing to do with being hurt by hammers, or doors.
