Let's say that writing and literature are not the same. They rarely look the same with different forms, paragraphs, settings and subject matter-introspective rather than appealing to surface understandings. Journalism is writing, unless it claims to also be literature (the claiming is important) because its writing is reflective, carries emotion laden adjectives, concrete symbols and some very long sentences. Is the vocabulary and the use to which it is put the difference? Shakespeare was, it seems, congenitally unable to write reportage, but nevertheless wrote ideas into his scripts.
And yet-----George Orwell's journalism is uniformly considered literature. Mainly because of its style! His style is often bare with a clear connection to the work of Daniel Defore, who never considered himself an artist.
Kissinger did not write literature preferring to explain his views without reflection, except in his arguments. Also, Kissinger did not actually write Diplomacy, only parts. Others did. And yet, neither did Alexander Dumas write his famous novels but gave chapters or parts of chapters for others to write. Is there a distinction between Good Writing and Literature?
