After the Soviet collapse, Marxism is a relic, a pathetic anachronism reduced to its last redoubts: North Korea, Cuba, and the English departments of the more expensive American universities.

Clashes of values and the struggle for primacy constitute a constant in human history that accounts for that other constant - conflict and war.

A one-hour work-week...would minimize the damage that Congress can do.

Obama's Democrats have become the part of no. Real cuts to federal budget? No. Entitlement reform? No. Tax reform? No. Breaking the corrupt and fiscally unsustainable symbiosis between public-sector unions and state governments? Hell no.

There's no free lunch. If you want an industrial economy, you need energy. If you want energy, it will produce pollution. You can have it in two forms. You can have it dissipated in the atmosphere - like carbon dioxide - which then you cannot recover, or you can have the waste concentrated in one small space like nuclear. That is far easier to deal with. The idea that you can be able to create renewable energy at a price anywhere near the current price for oil or gas or coal is a fantasy.

The Obama foreign policy, in broad strokes, has been a disaster.

I don't think you can pump carbon dioxide into the atmosphere indefinitely and not have a reaction. But there are great scientists such as Freeman Dyson, one of the greatest physicists of the last hundred years, who has studied the question, who believes quite the opposite. The reason transnational action is so difficult is because the major problem with climate change is, A, that there is no consensus, and, B, that the economic cost is simply staggering. Reversing it completely might mean undoing the modern industrial economy.
