At last! The philosophy of reality, reasoning independent minds, individual self-interest, and a free market society always had to recognize that its movement had to embrace all of these within itself. Yet the Ayn Rand Institute long refused to do this. To an apparently significant degree, ARI is now ready to do a better job of doing so and allow a popular movement to blossom without excessive schisms and attempts to control all Objectivist thinkers.
We have always needed more recognition that independent-minded individuals with their many varied interests and experiences would reasonably hold somewhat different principles and apply them to the complexities of life differently. Objectivism as a philosophy by which one can live your own life, has to contain within it the flexibility to handle the salient fact of our individuality. Yes, at a high level we all agree on some central principles, but in our individual lives one has to work out a host of sub-principles that apply to yourself as an individual. One cannot apply to Ayn Rand or to ARI for approval of how you make these judgments, because "No matter how vast your knowledge or how modest, it is your own mind that has to acquire it."
To be a successful movement, the Objectivist movement needs to believe that there is a free market in Objectivist ideas. That market of rational, independent-minded individuals will sort out the good and the bad ideas. Unfortunately, some Objectivists had too little confidence that there were enough rational, independent-minded individuals for this to work out successfully. Yet only if there are, will Objectivism ever succeed as a major popular movement.
See The Atlas Society comments on the ARI release for the main ways in which the ARI policy will now open up Objectivism to more independent-minded thinkers. Robert Tracinski has also made interesting observations on this.
