Why does Nietzsche think that truth is metaphorical or figurative, instead of literal?

Normal, college-level expectations for essay-writing apply.
You need to have a thesis (stake a claim about the topic)–the more interesting, the better.
You need to argue in favor of that thesis—persuasively lead your leader towards you conclusion.
You need to provide concrete, evidential support for that argument (this evidence should primarily come from the texts that we have read and discussed).
And you need to present your ideas sympathetically, with the reader in mind, in a clear and compelling way.
Your paper should be no more that 1250 words long, with 12 point font and double-spaced.
You need to submit your paper electronically, through the “turnitin” dropbox available on the course website (see the main menu for the dropbox link).
