“There is far more to the Islamic way of life than fasting and segregating women, of course. Praying five times a day, avoiding alcohol, the custom of eating with the right hand, leaving the left for ablutions and many health measures associated with Islam, such as ritual washing. Then there is the Qur’an itself and the sonorous power of the Arabic language, with an attractive system of ethics including a focus on alms-giving and the equality of believers. Putting all this together created a powerful religious technology which made its followers more aggressive, confident, united and with a higher birth rate than any competing civilization.

People in the West see the traditional culture of the Muslim Middle East as primitive and “backward,” and there are constant calls for modernization. In fact, as had been seen, Islamic culture is anything but backward. Civilization first arose in Egypt, Mesopotamia and the Indus Valley in what is now Pakistan. It is no coincidence that these lands, with the longest experience of civilization, are now strongly and fervently Muslim. Long experience of civilization has bred a high-S genotype and culture which perfectly adapt people to survive and expand their numbers in dense agricultural and urban populations.

Such countries tend to be poor (if we leave out the anomalous effects of oil wealth), since their peoples lack the temperament for industrialization. But wealth at that level is of no benefit in the long-term struggle for survival and success. To paraphrase Christian scripture, what does it benefit a civilization if it gains wealth but loses its strength and vigor? The advantages of Islam can be clearly seen in countries with mixed populations. Lebanon once had a Christian majority but is now 54% Muslim. In Communist Yugoslavia the provinces with Muslim populations grew much faster and received tax revenue from the wealthier Christian states. The population of Kosovo, the spiritual homeland of Christian Serbia, grew from 733,000 in 1948 to over two million in 1994, with the Muslim component surging from 68% to 90%, and lately going even higher.

Meanwhile, Muslims are migrating into Europe where Christianity is in decline, the birth rate is far below replacement level, and people no longer have much faith in their own culture. Over the next few decades, as the next chapter will indicate, the native peoples of the West will become feebler and fewer. This means that on current trends Europe will become an Islamic continent in a century or so. The 1,400-year struggle between Islam and the West is coming to end.
