A mineral always contains certain elements in definite proportions
In the logical sense, sentences must be either true or false and not both. "This sentence is false" cannot be true because that would mean that it is false, and it cannot be both. It also cannot be false because that would mean that it is true, and it cannot be both. Therefore, if it is true or false, then it is both true and false. Therefore it is either neither true nor false or both true and false; therefore, in the logical sense, it is not a sentence. However, it says it is a sentence; therefore, it is lying; therefore, it is false.
A declarative sentence is a statement that conveys information and can be classified as either true or false. For example, "The Earth orbits the Sun" is a true declarative sentence, while "Cats can fly" is a false declarative sentence. These sentences provide facts or assertions that can be verified.
