Arbitrariness/Arbitrary/Law/Physics/Laws of Nature/Wittgenstein: E.g. perturbations: it is arbitrary whether we declare our laws to be right, and say we just do not see the planet, or whether we call the laws incorrect. - If we say that a planet must be nearby, we define a grammatical rule.

Arbitrariness/Arbitrary/Grammar/Rules/Purpose/Wittgenstein/Schulte: E.g. the rules of cooking are not arbitrary, because they are defined by the purpose of cooking. - On the other hand: Grammar: is not defined by the purpose of language - only the grammatical rules constitute the meaning. - Therefore, they are not committed to any meaning. - ((s) Grammar/Wittgenstein: = logic).
