| Deduction | Deduction is to draw an inference about a specific instance from a general principle. |
| Evidence | Evidence is support, including physical objects, offered as proof that something is true or that it has or had existence. |
| Fact | A fact is something proven to be true, real, existing or to have existed. |
| Hidden premise | Hidden premise is a made claim in support of a conclusion that is implied but not stated. When not exposed, it can lead to the acceptance of a false conclusion. |
| Infer | To use imagination and reasoning to fill in missing facts. To connect the dots. |
| Logic | Logic is the science of good reasoning. |
| Opinion | Opinion is an interpretation or conclusion about experience. It is one word used to designate a belief, a supported argument, an expert’s judgment, prevailing public sentiment, and a formal statement by a court. |
| Syllogism | A syllogism is the standardized form that makes the structure of a deductive argument visible. A syllogism consists of two premises or claims followed by a conclusion inferred from these premises. |
| Thinking | Purposeful mental activity such as reasoning, deciding, judging, believing, supposing, expecting, intending, recalling, remembering, visualizing, imagining, devising, inventing, concentrating, conceiving, considering. |
| Valid and sound | A valid deductive argument is one in which the conclusion is correctly inferred from the premises. An argument is sound when the conclusion cannot be false because the premises are true and the reasoning is valid. |
