Rand is widely believed by her followers to have solved most of the major philosophic questions. For example, she is thought to have answered what has come to be known as Hume's "problem of induction."
But did she in fact do this? Sadly, no:
Prof M:"The question is: where does one stop? When does one decide that enough confirming evidence exists? Is that the province of the issue of induction?
Rand: "Yes. That's the big question of induction...Which I couldn't even begin to discuss - because...I haven't worked on that subject enough to even begin to formulate it..." - Introduction To Objectivist Epistemology p304
