    Henry S. Leonard (1959). Interrogatives, Imperatives, Truth, Falsity and Lies. Philosophy of Science 26 (3):172-186.
    This paper aims to establish three major theses: (1) Not only declarative sentences, but also interrogatives and imperatives, may be classified as true or as false. (2) Declarative, imperative, and interrogative utterances may also be classified as honest or as dishonest. (3) Whether an utterance is honest or dishonest is logically independent of whether it is true or is false. The establishment of the above theses follows upon the adoption of a principle for identifying what is meant by any sentence, (...)

    Henry S. Leonard (1959). Authorship and Purpose. Philosophy of Science 26 (4):277-294.
    This paper approaches a theory relating authorship, meaning and purpose by semiformalized developments of two "presupposed theories": of purposeful behavior and of sign-reading. The theory of purposeful behavior is made to rest upon two undefined predicates. `Wt(a,p,q)' abbreviates the claim that at time t, person a works at bringing it about that p in order to bring it about that q. `Bt(a,p)' abbreviates the claim that at time t, person a brings it about that p. A number of definitions and (...)
