The logical constants are defined by operational rules in the inferentialism theory of meaning. Arthur Prior’s counterexample (Tonk) makes a major challenge for the inferentialism. He shows that every arbitrary operational rule can describe a logical constant and this makes logical constants defective and incompatible with the system. In response to this problem, Belnap Offers conservativeness and uniqueness requirements for the operational rules. In this paper, we have evaluated the conservativeness requirement. The main question investigated is “how the conservativeness as a criterion provides the necessary and sufficient conditions for logical constant definition?” The hypothesis that we are to establish is the inability to achieve the definition of logical constant by conservativeness requirement.
