 We have touched only on a few central aspects of the notion of logical consequence, leaving further issues, debates and, in particular, details to emerge from particular accounts (accounts that are well-represented in this encyclopedia). But even a quick glance at the related links section (below) will attest to a fairly large number of different logical theories, different accounts of what (logically) follows from what. And that observation raises a question with which we will close: Is there one notion of logical consequence that is the target of all such theories, or are there many?
