I do not have access to specific details about Wolfram Eilenberger's description of Ayn Rand's writing or her personality as a "narcissistic personality disorder."
However, I can offer some general insights about Ayn Rand's writing and its reception. Ayn Rand was a philosopher and novelist known for her philosophy of Objectivism, which emphasizes rational self-interest, individualism, and laissez-faire capitalism. Her most famous novels, "Atlas Shrugged" and "The Fountainhead," are widely regarded as literary works that promote her philosophical ideas.
Critics of Rand's writing have argued that her characters often embody extreme, one-dimensional traits, and that her philosophical views can be seen as promoting a form of egocentrism or self-centeredness. Some have suggested that the emphasis on individualism and self-interest in her philosophy may be interpreted as narcissistic.
However, it is essential to recognize that opinions on Rand's work vary widely, and any diagnosis of a personality disorder should be made by qualified professionals based on in-depth analysis and assessment. Describing an individual, especially a historical figure like Ayn Rand, as having a personality disorder should be approached with caution, as it requires a comprehensive understanding of the person's life and behaviors.
If Wolfram Eilenberger has made such claims about Ayn Rand, it would be best to refer to his specific writings or interviews for a more nuanced understanding of his viewpoint. It is also essential to engage with multiple perspectives and conduct independent research when evaluating the assessments of public figures.
