Structural rule A famous structural rule is known as cut. Considerable effort is spent by proof theorists in showing that cut rules are superfluous in various logics. More precisely, what is shown is that cut is only (in a sense) a tool for abbreviating proofs, and does not add to the theorems that can be proved. The successful 'removal' of cut rules, known as "cut elimination", is directly related to the philosophy of "computation as normalization" (see Curry–Howard correspondence); it often gives a good indication of the complexity of deciding a given logic. Structural rule In proof theory, a structural rule is
Community Rule 30% of the scrolls are classified as "sectarian". The most complete manuscript of the Community Rule was found in Cave 1, and was first called the Manual of Discipline by Millar Burrows. It is now designated 1QS (which stands for : "Cave 1 / Qumran / "Serekh" = 'rule'). Numerous other fragments of this document, containing variant readings, were found in caves 4 and 5 (4QS, 5Q11, 5Q13). Two other documents, known as the Rule of the Congregation (1QSa) and the Rule of the Blessing (1QSb), are found on the same scroll as 1QS and while they were originally thought
