Commitment (philosophical)(A theory's commitments are the things it claims exist or must be the case): What a theory or belief system says must be true or exist if that theory is correct.
Formal system(as used in logic and mathematics): A set of rules and symbols (like mathematical axioms) that you use to prove whether statements are true or false, similar to how a chess game has specific rules that determine what moves are legal.
Quine(as a proper name referring to the philosopher whose theory is being discussed): Willard Van Orman Quine was a 20th-century American philosopher who wrote about how we know things and how language works. In this statement, we're discussing one of his specific ideas about observation.
