After a concise introduction about the idea of correspondence and correlation, in the first part of the paper two notions of information are grasped by the analysis of Situation Semantics and Situation Theory. The first is that of correlation, the second that of constraint; the latter is reducible to the former. More than that, the phenomenon of the 'alethic nature of information' is highlighted, a clear concept of information is gained and the nutshell of any possible 'informational theory of truth' is pointed out.

In the second part, an informational epistemological synthesis and conception of language is propounded. The difference between a meaning-oriented language and an informational-oriented language is outlined. The architecture of an informational-oriented language is shown and 'messages' are recognized as being the atomic constituents of language. In the conclusion, the attention is focused on a naturalized epistemology of information and language.
