Prescriptive Claims and Value Judgements

In chapter two of the textbook, "Critical Thinking", Prescriptive Claims, Descriptive Claims and Value Judgments are discussed. A prescriptive claim is a claim that tells the reader what should be. For example, "Wearing animal fur as clothing is cruel," is a prescriptive claim because it is telling the reader they should not wear animal fur as clothing. A descriptive claim  just states something and does not say what should be like a prescriptive claim. An example of a descriptive claim is, "Bob has a blond hair." A value judgement is a very vague claim that suggests what is right, wrong, good, bad, better, worse, etc. One example of a value judgement is "Doing drugs is bad." This sentence is a value judgement because it is vague and has the word, "bad". The word, "bad," implies what people should not do. The sentence is vague because there are many questions that could be asked about it. For instance, which drugs? Coffee is a drug, is that bad too? How are drugs bad? Bad for a person emotionally or physically?
