Document Summary
Claims are distinct from questions or explanations. Symbolizes an inference which describes how the premises are connected to the conclusion. Deduction: if the premises are true, then the conclusion must follow. Induction: if the premises are true, then the conclusion is likely true. The basic form of the syllogism is categorical: major premise. Propositions are the basis of logical reasoning. Logical induction involves instances in which premises indicate support for the conclusion but do not entail the conclusion. Strength: the probability that the conclusion is true given that all the premises are true. Cogency: the soundness of the argument in terms of its form and organization. Claim: the claim is the conclusion or explicit appeal produced by the argument, the claim is always controversial. Warrant: provides the reasoning or logic that justifies using the evidence to support the claim, it authorizes the mental leap involved in advancing from data to claim.
