... logic. L is closed under truth-functional operations. (Thus, if α ∈ L then ¬α ∈ L, and if α ∈ L and β ∈ L then α ∨ β ∈ L, α ∧ β ∈ L, α → β ∈ L, etc.) Lower-case Greek letters α, β, γ, . . . range over formulas. Upper case letters A, B, . . . , S, . . . , W, X, Y, . . . represent sets of formulas. M ...
