A sound argument is a type of argument that is logically valid and has true premises. In other words, it is an argument in which the conclusion logically follows from the premises, and the premises themselves are true. A sound argument must meet two criteria:
1. Logical Validity: This means that the structure of the argument is such that if the premises are true, the conclusion must also be true. In a sound argument, there are no logical fallacies or errors in reasoning.
2. True Premises: The premises of a sound argument are statements or facts that are actually true. The truth of the premises provides solid evidence or support for the conclusion.
To determine if an argument is sound or not, you need to evaluate both the logical structure and the truth of the premises. If the argument is both logically valid and has true premises, then it can be considered a sound argument.
