I don’t agree with much of what David Bentley Hart says in his article, “The Trouble With Ayn Rand,” but what he says about objectivism in the following paragraph is essentially correct:
"And, really, what can one say about Objectivism? It isn’t so much a philosophy as what someone who has never actually encountered philosophy imagines a philosophy might look like: good hard axiomatic absolutes, a bluff attitude of intellectual superiority, lots of simple atomic premises supposedly immune to doubt, immense and inflexible conclusions, and plenty of assertions about what is “rational” or “objective” or “real.” Oh, and of course an imposing brand name ending with an “-ism.” Rand was so eerily ignorant of all the interesting problems of ontology, epistemology, or logic that she believed she could construct an irrefutable system around a collection of simple maxims like “existence is identity” and “consciousness is identification,” all gathered from the damp fenlands between vacuous tautology and catastrophic category error. She was simply unaware that there were any genuine philosophical problems that could not be summarily solved by flatly proclaiming that this is objectivity, this is rational, this is scientific, in the peremptory tones of an Obersturmführer drilling his commandoes.”Rand’s philosophy is too simplistic and immature to be regarded as a real philosophy. I expressed my on doubts about objectivism (which I prefer to spell with small "o") in my post: "Is Ayn Rand’s Objectivism a Philosophy?"
