Richard L. Epstein and Carolyn Kernberger state that there are two different types of claim, a subjective and objective claim. A subjective claim is a type of claim that expresses truth base on someone’s belief and on his/her personal preference. It cannot be proven right or wrong. A objective claim is a claim that is factual and not based of personal beliefs. Therefore, objective claims can be proven right or wrong.
I would have to say I use subjective claims everyday. We will always choose want we prefer. For example, my hobby is to scrapbook. I find it fun and relaxing than blankly inserting them into an album. Not everyone will have patience to put scraps together or even take the time to arrange pictures. Epstein and Kernberger will call this a subjective claim because it is my own personal standard.
Objective claims are more used for impersonal standards, like what we don’t have control of, such as the law and market prices. For example, I recently rented a textbook for $60. It wasn’t my choice to pay $60, it was the company’s choice to set the price. We are able to prove if it's right or wrong by going to the bookstore and check the price.
