Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student
In logic, the term statement is variously understood to mean either:
- a meaningful declarative sentence that is true or false, or
- a proposition. Which is the assertion that is made by (i.e., the meaning of) a true or false declarative sentence.
By a statement, I mean "that which one states", not one’s stating of it. There are many interpretations of what the term statement means, but generally, it indicates either a meaningful declarative sentence that is either true or false ("bivalence"). As you might expect, a proposition is an assertion that is made by (i.e., the meaning of) a true or false declarative sentence. A proposition is what a statement means, it is the notion or idea that a statement expresses, i.e., what it represents. It could be said that "2 + 2 = 4" and "two plus two equals four" are two different statements that are expressing the same proposition in two different ways.
