CH 13- Deductive Reasoning
Deductive reasoning is the process of starting with one or more statements called premises. Deduction is the study of formal logic, or the science of good reasoning. It is called formal because its main concern is with creating forms that serve as models to demonstrate both correct and incorrect reasoning. Reasoning draws conclusions, judgements, or inferences from facts or premises. Logic arranges deductive arguments in standardized forms called syllogisms, that make the structure of the argument clearly visible for study and review.

CH 12- Arguments
Arguments can be logical structures that people use when they write and speak to present ideas and to persuade others to support those ideas. It consists of two or more statements that include one conclusion and at least one reason that supports it. Arguments can be evaluated using specific criteria including determining dependability, distingushing fact from opinion, and detecting fallacies. The two primary types of arguments are deductive and inductive. Deductive arguments have at least one premise that logically leads to a conclusion. Inductive arguments begin with a series of specific observations and conclude with a generalization that logically flow from them.
