 As Ripley (2011b) remarks, rejectivists are typically inferentialists, i.e., they hold that the meaning of the logical operations can be explicated in terms of meaning-conveying rules. If inferentialism is developed in terms of rules for asserting and rules for denying compound formulas (as, for example, in Price 1983, 1990; Rumfitt 2000) according to Ripley (2011b), the above questions can be answered by explaining that negation is a switch between warranted assertability conditions and warranted deniability conditions. This role of negation is similar to the role strong negation in Nelson’s logics plays in turning support of truth conditions into support of falsity condition, and vice versa. Price (1990, 225) argues that
