Why are some people still following objectivism as a philosophy?
As an academic theory objectivism seems to be dead (well it really was a stillborn). Sidorsky called it "more of an ideology than a consistent philosophy". Rand had no positive connections with philosophers of her time nor was her philosophy later picked up by anyone (with very few exceptions). She is not even included in the Oxford Companion on philosophy. This can hardly be explained by bias, as other fiercely anti-left philosophies are represented in academia and included in the companion. She is also only really popular in the US suggesting she is more of a cultural phenomenon.
Her theory includes logical errors (like concluding an "ought" from an "is" - classic example of Humes law). Objectivism also failed to even give an accurate description of capitalist society. Modern capitalist societies would not only immediatly collapse without unpaid labor and solidarity but also because people would simply dismantle the private property order of capitalist society - she misses the point the state plays in even maintaining the capitalist order. Without a strong state there is no capitalism: neo-liberalism knows this, which it way it advocates for a strong state in economic matters.
So why take her seriously as a philosopher and not simply as a cultural phenomenon in the US?
