Here; an excerpt:

[I]n the  Stanford Encyclopedia of Philosophy entry on Rand,  its authors write that “her advocacy of a minimal state with the sole  function of protecting negative individual rights is contrary to the  welfare statism of most academics,” claiming outright that the  overwhelming majority of professional philosophers and political  theorists have been simply unable to fairly evaluate her work because of  the biasing factor of their prior political commitments.

 

Somehow the same ‘welfare statism’ of academics has not prevented the close study of Robert Nozick’s landmark Anarchy, State and Utopia,  a sophisticated libertarian text that mounts an original, and far more  effective, argument against redistributive policies. Apart from John Rawls’ A Theory of Justice, there is perhaps no more commonly-assigned book in undergraduate political philosophy classes.

 

Surely  there must be some other reason for Rand’s academic neglect. The  authors of the SEP entry do go on to suggest an additional number of  largely psychological hypotheses having to do with Rand’s dogmatic tone,  cult-like following, and emphasis on popular fiction–never  entertaining the possibility that professional philosophers think her  work is, quite simply, of poor quality. Objectively, ahem, speaking.
