to ourselves and our posterity

Magna-cartwheeling, noun: the rhetorical acrobatics used by certain American jurists (e.g. Scalia, Kennedy) to astrally project themselves to the rolling meadows of merry olde England, in an attempt to gaze soulfully into the eyes of ye olde free Englishman to discover what freedom means to him, specifically whether it includes oral contraception and/or Kalashnikov rifles.
