Principle of Bivalence
The principle of bivalence states that every proposition has exactly one truth value, either true or false. This is very similar to the law of excluded middle but can be shown to have semantic differences.Summary
The law of excluded middle is a simplification that is adopted as an assumption or constraint for system of logic. This is not very pragmatic for real world applications because practically every statement that is made by humans and machines is in some grey area such as partially true or mostly false. For this reason, modern pursuits are more likely to rely on systems such as probabilities that can handle grey areas.
