I just don't understand whata declative sentence is in philosophy, I know that all a declarative sentence, is a sentence in the form of a statment. My prof is asking for a detailed answer, and im not really sure. . . I know that they are in arguments, and each argument must have at least 2 declarative sentences. One declarative sentens is supposed to be supported by the rest of the declarative sentences? I really just don't comprehend it.
