We’ll see, though, that almost everyone adopts the nihilistic stance at times, without noticing. When the complete stance is unknown, nihilism seems like the only possible defense against the harmful lies of eternalism. (Just as eternalism seems like the only possible salvation from the harmful lies of nihilism.)
The nebulosity of meaningness causes various problems: practical, social, and psychological. (Much of this book describes such problems.) Often, people would like to get rid of nebulosity, or pretend that it is not there.
Confused stances are attitudes to meaningness that refuse to acknowledge nebulosity. One strategy is to fixate meanings, attempting to deny their nebulosity by trying to make them solid, eternal, and unambiguous. Another is to deny meaningfulness altogether, or to say that it is not important, or cannot be known.
Because meaningness is both nebulous and real, these confused stances fail, and cause new, worse problems.
