The last is of the type cited in §908. It is unanswerable since the answers yes and no alike confirm an assumption. An affirmative or negative answer to the double question, e.g., ‘Is the world finite? infinite?’ alike both affirm the ideas worded by ‘world’ and ‘is’ as unquestionably valid ideas not subject to analysis; affirmative or negative answers to the quadruple question, e.g., ‘After death, does a Perfect One exist? not exist? both exist and not exist? neither exist nor not exist?’ alike all affirm a ‘person’ and ‘being’ (existence) as unquestionably valid ultimate ideas not subject to analysis.
But the Buddha put Being (existence and non-existence) into question, placing it in perspective with Consciousness in the pattern of Dependent Arising. There they cannot become rivals for meta-physical Absoluteness, and are subordinated to Action and its Cessation.
