Facts are verifiable information. Simple facts are often stated as propositions: "Apples are a type of fruit." The opposite statement—"Apples are not a type of fruit"—is still a properly formulated proposition, even though it is false (not a fact). Most statements of fact are compound facts: e.g., that apples exist, that fruit exists, that there are multiple types of fruit, etc.
A premise is a proposition that is used as the foundation for drawing conclusions. For example:
- Premise: "Apples are a type of fruit."
- Premise: "All types of fruit are food."
- Conclusion: "Therefore, apples are food."
If the conclusion is false then either one or more of the premises is false or the process of combining the premises is logically invalid. If the premises are true and the process is logically valid, then the conclusion must be true.

“Once one is caught up into the material world not one person in ten thousand finds the time to form literary taste, to examine the validity of philosophic concepts for himself, or to form what, for lack of a better phrase, I might call the wise and tragic sense of life.”
—F. Scott Fitzgerald (1896–1940)
