  In this paper I show, with a rich and systematized diet of examples, that
many contra-classical logics can be presented as variants of FDE, obtained by
modifying at least one of the truth or falsity conditions of some connective.
Then I argue that using Dunn semantics provides a clear understanding of the
source of contra-classicality, namely, connectives that have either the
classical truth or the classical falsity condition of another connective. This
requires a fine-grained analysis of the sorts of modifications that can be made
to an evaluation condition, analysis which I offer here as well.
