Final answer:
The value of a promise or agreement lies in establishing trust and cooperation. These rules create a sense of predictability and reliability, allowing people to make plans, establish trust, and maintain a civilized society.
Step-by-step explanation:
The reasoning or logic behind the value of a promise or agreement lies in the fact that it establishes trust and cooperation among individuals or entities.
Promises and agreements provide a sense of security and assurance that parties involved will fulfill their obligations and keep their word.
For example, in the goods market, a seller may offer a money-back guarantee as a promise of quality.
This encourages customers to buy products, even if they are unsure, because they know they can rely on the seller's promise to provide a refund if the product doesn't meet their expectations.
In a broader sense, moral rules, such as keeping promises and telling the truth, are necessary for harmonious social interactions.
These rules create a sense of predictability and reliability, allowing people to make plans, establish trust, and maintain a civilized society.
