Nay, much rather (alla pollwi mallon). Adversative sense of alla, on the contrary. So far from the more dignified members like the eye and the head being independent of the subordinate ones like the hands and feet, they are "much more" (argumentum a fortiori, "by much more" pollwi mallon, instrumental case) in need of therm. Those members of the body which seem to be more feeble are necessary (ta dokounta melh tou swmato asqenestera uparcein anagkaia estin). Things are not always what they seem. The vital organs (heart, lungs, liver, kidneys) are not visible, but life cannot exist without them.
