Existence of Satisfied Alternative and the Occurring of Morph-Dictator

摘要

In social life of human being, individuals or collective group will be always confronted with choices. The occurring of choice implies that rational action agent (individual, collective group or social group in wide sense) must make a satisfying decision based on the alternatives set whose cardinal number is at least 2. Choice depends on preferences (Fishburn (1979)), so the nature of choice can be deemed to preference whether for individual or collective group. Preference is the ordering of alternatives given by rational agent according to his own will based on the sensibility and proneness. Preference can be crisp and fuzzy also.
