The Guardian has an article on the current Ayn Rand revival.
There's an Ayn Rand revival in America these days. Sales of her books Atlas Shrugged and The Fountainhead have skyrocketed in the past year, along with the number of Rand-themed articles in mainstream publications.
The central philosophical (and indeed, scientific) problem for individualists like Rayn is the fact that homo "sapiens" is a social animal.
Individualism is an idealism in an age when all philosophers are non-idealists. The idea of a free individual is an abstraction. We are all constrained by physical needs (food, water, shelter &c) and also social needs. Within that framework we must find out how to maximise freedom.
So the resurgence of individualism in its various forms (from neo-con to libertarian) would be funny if it were not so serious.
Individualists form the core of the global warming denialist lobby, working along the following lines:
*I am an individual who chooses to do whatever pleases me
*My high carbon lifestyle pleases me
*AGW theory compels all humans to change to a zero-carbons lifestyle
*Therefore AGW theory is wrong.
