Abstract
The title question should be construed as an epistemological and not ontological one. Omitting the difficult problems of the ontology of intentionality we will ask, if all, what is needed to explain the phenomenon of meaningful use of words, could be found “in our private head” interpreted as a sphere of specific privileged access, the sphere that is in the relevant epistemological sense subjective, private or non public.
There are many “mentalistic” theories of meaning that force us to the answer: “yes”. According to these theories our words are meaningful in virtue of some intentions of the speaker. And our intentions consist in having some mental states that should be in the relevant sense subjective or private. (Searle, Chisholm) But there are also the philosophers (Kripke, Putnam) who claim to have the evidence to the contrary. They argue that the meanings of our words could not be “in the head”, because of two important reasons. (i) Very often we don’t know exactly the meanings of the words that we use meaningfully. Furthermore, our “semantical self-knowledge” is principally corrigible by other people, and hence our access to the meanings we use could be by no means privileged. And secondly (ii) we can imagine a situation in which two subjects with the same mental intention use the same word with the very different meanings.
We will investigate our question on the ground of the Ingarden’s philosophy. As we will see, his answer turns out to be in an interesting sense: “yes and no”.
