Document Summary
We need to ask two questions to decide whether arguments are good. Corresponding to them , weave introduced the concepts of validity and soundness. A general sense of validity (denying the conclusion is incompatible with accepting the premises) and the formal sense of validity (the argument has a valid argument). Statements are sentences that can be true or false. If a sentence is not a statement, it can contain a statement, in which we call the contained statement a component statements. Component statements are still those you can answer true or false . A component statements: a series of words in a statement, if substituting it by any other statements results in a meaningful statement. Simple and compound statement: is a statement that has no component (other than itself) A compound statement: any statement that contains one or more component statement (that isn"t itself).
