All Fours
.To go on all fours is to crawl about on knees and hands like a little child.
It does not go on all fours means it does not suit in every minute particular; it does not fully satisfy the demand. It limps as a quadruped which does not go on all its four legs. Omnis comparatio claudĭcat (all similes limp).
“No simile can go on all-fours.”
