During Rand's lifetime, her work received little attention from academic scholars. When the first academic book about Rand's philosophy appeared in 1971, its author declared writing about Rand "a treacherous undertaking" that could lead to "guilt by association" for taking her seriously. A few articles about Rand's ideas appeared in academic journals before her death in 1982, many of them in "The Personalist". One of these was "On the Randian Argument" by libertarian philosopher Robert Nozick, who argued that her meta-ethical argument is unsound and fails to solve the is–ought problem posed by David Hume. Other philosophers, writing in the same publication, argued that Nozick misstated Rand's case. Academic consideration of Rand as a literary figure during her life was even more limited. Academic Mimi Gladstein was unable to find any scholarly articles about Rand's novels when she began researching her in 1973, and only three such articles appeared during the rest of the 1970s.
