Sound arguments are both valid and true from "summary" of Art of Logical Thinking by Atkinson William
The concept that sound arguments are both valid and true is essential in the realm of logical thinking. A valid argument is one in which the conclusion logically follows from the premises. In other words, if the premises of an argument are true, then the conclusion must also be true. This is the hallmark of a valid argument - it is structured in such a way that if the premises are true, the conclusion must also be true. However, validity alone is not sufficient for an argument to be considered sound. In addition to being valid, an argument must also have true premises. This is where the notion of truth comes into play. A sound argument is one that is not only valid but also based on true premises. If the premises of an argument are true, and the argument is valid, then the conclusion must necessarily be true as well. It is important to understand the distinction between validity and truth in arguments. Validity refers to the logical structure of an argument, while truth pertains to the actual content of the premises. A valid argument can have false premises and still be valid, but it would not be considered sound. On the other hand, a sound argument is one that is both valid and based on true premises.- The concept that sound arguments are both valid and true is crucial in the realm of logical thinking. Validity ensures that the conclusion logically follows from the premises, while truth ensures that the premises themselves are accurate. When an argument is both valid and based on true premises, it is considered sound. This distinction is important in evaluating the strength and validity of arguments in various contexts.
