ten tiny levers that built every cathedral, fired every gun, and typed every lie
means The five jointed digits at the end of each hand, used for grasping, touching, pointing, and manipulating objects.
from From Old English 'finger,' a solidly Germanic word with cousins all over the family — German 'Finger,' Dutch 'vinger,' Old Norse 'fingr.' Scholars often link it back to a Proto-Indo-European root 'penkwe' meaning 'five,' the idea being that a finger is literally 'one of the five' — making the hand a built-in counting frame. That connection is plausible and widely cited, though not airtight; what's certain is the word has stayed remarkably unchanged for well over a thousand years, gripping the language as stubbornly as the things themselves grip the world.
