認知活著的能力的邊界條件 Boundary Condition for Ability to Recognize Living

嬰兒，於初生之際，因智力未成熟而無法認知活著。	An infant, at the time of his birth, is unable to recognize his living because his intelligence has not been developed.
老人，於因智力已退化而無法認知活著之際，臨死。	An old man, at the time when he is unable to recognize his living because his intelligence have been degraded, is about to die.
活著的認知，屬於後設認知。	The cognition of living is a metacognition.
