Philosophy Informal Logic Questions
In informal logic, a valid argument refers to the logical structure of an argument, where the conclusion follows logically from the premises. It means that if the premises are true, then the conclusion must also be true. Validity is determined by the logical relationship between the premises and the conclusion, regardless of the truth or falsity of the statements.
On the other hand, a sound argument not only has a valid logical structure but also has true premises. In other words, a sound argument is both valid and has true premises, ensuring that the conclusion is not only logically valid but also factually correct.
In summary, the difference between a valid and a sound argument in informal logic is that validity focuses on the logical structure, while soundness additionally requires true premises.
