Complexe significabilia are the significate of whole sentences, irreducible to what is signified by categorematic sub-sentential components. It has been propounded firstly by Adam Wodeham. Wodeham construes his argument for the postulation of complexe significabilia as a middle way between William of Ockham and Walter Chatton. According to Wodeham, Ockham’s view implies a reflexive theory of mental acts, which goes against the phenomenology of the act of assent. Moreover, it leads to an anti-realist epistemology. We need therefore things outside the (...) mind to be object of the act of assent, which is also the conclusion reached by Chatton. However, against Chatton, Wodeham argues that things signified by the categorematic component of sentences cannot be the object of assent. In effect, sentences with different syncategorematic structures, but with the same categorematic components, would correspond to the same propositional attitude in Chatton’s framework, which is an unwelcome consequence. The result is that we need to postulate that the objects of assent are outside the mind, contra Ockham, that are not signified by sentential categorematic components, contra Chatton, but are irreducibly signified by the whole sentences.
