    • The central role which proof theoretical methodologies play in generating logics compels us to put forward the view that a logical system is a pair (|~, S|~), where S|~ is a proof theory for |~. In other words, we are saying that it is not enough to know |~ to 'understand' the logic, but we must also know how it is presented (i.e. S|~).
    • A logical system is a pair (|~, S|~), where |~ is a structured-consequence, and S|~ is an algorithmic system for it.
