Our minds have been built by selfish genes, but they have been built to be social, trustworthy and cooperative.

It is not a zero sum game. The simple idea of the gains from trade lies at the heart of the modern and the ancient economy, not the power of capital. There is nothing else to it.

The interaction of genetic and external influences makes my behaviour unpredictable, but not undetermined. In the gap between those words lies freedom.

The average Mexican lives longer now than the average Briton did in 1955. Infant mortality is lower today in Nepal than it was in Italy in 1951. The proportion of Vietnamese living on less than $2 a day has dropped from 90 per cent to 30 per cent in twenty years. The rich have got richer, but the poor have done even better.

Prosperity has brought complications. Our lives are busier, faster, more stressful. They're nostalgic for a simpler, slower time.

The body is merely an evolutionary vehicle for the gene

The message from history is so blatantly obvious - that free trade causes mutual prosperity while protectionism causes poverty - that it seems incredible that anybody ever thinks otherwise. There is not a single example of a country opening its borders to trade and ending up poorer.
