  "body": "\n## Summary\n\nIn logic, a **strict conditional** (symbol: $\\Box$, or ⥽) is a conditional governed by a modal operator, that is, a logical connective of modal logic. It is [[logically equivalent|06GYGS41JK]] to the [[material conditional|0NMG7W7Q11]] of classical logic, combined with the necessity operator from modal logic. For any two [[propositions|0ZGC7ZESYN]] *p* and *q*, the formula *p* → *q* says that *p* [[materially implies|0NMG7W7Q11]] *q* while $\\Box (p \\rightarrow q)$ says that *p* strictly implies *q*. Strict conditionals are the result of Clarence Irving Lewis's attempt to find a conditional for logic that can adequately express indicative conditionals in natural language. They have also been used in studying Molinist theology.\n",
