TFY Chapter 12 - Deductive Reasoning

Deductive reasoning is the process of starting with premises and investigating what conclusions necessarily follow from these premises. Deduction is the subject of formal logic. Logic has its own vocabulary like: argument, claim and reasoning. Hidden premises or conclusions, hypothesis, inductive reasoning. Syllogisms determine what is being said to identify hidden premises, to find what makes sense. Deductive and inductive reasoning are mentally interwoven in problem solving.
