Usage notesEdit

  • For example, from the premises "all good people believe in the tooth fairy" and "Jimmy does not believe in the tooth fairy", we deduce the conclusion "Jimmy is not a good person". This particular form of deduction is called a syllogism. Note that in this case we reach a false conclusion by correct deduction from a false premise.
