| Term | Definition |
| inductive reasoning | reasoning that moves from the particular to the general – makes a generalization about a specific set of experiences. Child burns self on stove three times = "stoves burn." |
| deductive reasoning | reasoning that moves from the general to the specific – starts with a generalization then concludes with applying to a new situation. Can often be expressed as a syllogism. Deductive reasoning does not use a logical leap; instead, it relies on the reasoning process under the condition that the reasoning is valid |
| syllogism | : a piece of deductive reasoning contains a major premise, minor premise, and conclusion. |
