Document Summary
A and t are relevantly similar to degree n. When reasoning by analogy, the analogue must be: Her sister, jane, is similar to suzie: she is bright and works hard. Relevant but insufficient similarity (relevant but not enough) Jane is similar to suzie: she is bright. Therefore, probably, jane will do well this year. Jane is similar to suzie: she is tall and vegan. Therefore, probably, jane will do well this year another, we conclude something about the target (t) by comparing it to the analogue (a) If the premises are true, the conclusion must be true. Argument is valid and the premises are true, logical connection and true. Premises support the conclusion but argument may not be true, logical connection and possibly false (strong = connection, weak = no connection) A tool for evaluating the validity of deductive arguments, especially complex ones. What is the formula for validity and logical structure. If jim is an octopus, pigs will fly.
