* [[http://en.wikipedia.org/wiki/Nihilism Nihilism]] is simply belief in nothing, no more, no less; it isn't a BrownNote which makes a person GoMadFromTheRevelation, pushes him onto the DespairEventHorizon, turns his life into an instant CosmicHorrorStory, converts him into an [[OmnicidalManiac omnicidal]] CardCarryingVillain, or automatically turns him {{wangst}}y or depressed. There are also many interpretations for nihilism. For example, Metaphysical nihilism is a literal belief in nothing. Moral nihilism is the view that morality does not exist as something inherent to objective reality; therefore no action is necessarily preferable to any other. For example, a moral nihilist would say that killing someone, for whatever reason, is not inherently right or wrong. Existential nihilism is saying life is meaningless and insignificant -- the form of nihilism which is often portrayed in this trope.
** However, this is a true MindScrew. How does one believe in nothing, and yet believe this belief is truth? Because truth is something, but...
*** Generally they don't. Stuff about the illusion of consciousness and the inability to perceive the universe objectively is a big part of a lot of nihilism's various varieties; they're just going with an idea that may or may not be true but is the most likely outcome based on their scientific/metaphysical/whatever beliefs. This is also why it's not a magical brown note that makes people immediately commit suicide; pragmatism is still a thing, and it's still completely feasible to live a normal life while maintaining that the universe has no objective order to it. Recognizing your reproductive instincts as a biological mechanism doesn't stop you from feeling them, for example.
* For more trivial matters, see TheOtherWiki's entry on [[http://en.wikipedia.org/wiki/Friedrich_Nietzsche Friedrich Nietzsche]], who never actually encouraged you to be a nihilist. On the contrary, he'd have urged you to say "yes" to life, by which he means [[TheUbermensch making it worth living by your own standards]].
* In ''The Antichrist'', Nietzsche tried to portray [[Literature/TheBible St. Paul]] as this character type who [[WordOfDante twisted]] Jesus' words to mean HappinessInSlavery. (He saw JesusChrist himself as being an example of TheUbermensch -- [[JesusWasWayCool one who lived his life by his own rules and made it joyful, without having any regrets]].)
