Technology in the West has enormously advanced, but the human mind, although flexible, is not adaptable to the point of making the rapid changes that may be the consequence or the accompaniment of this technology.
Aeroplanes can now cover distances to the other side of the earth, the opposite hemisphere and remote latitudes in a minuscule fraction of the time it was taking even one or two centuries ago.
But the people transported by the aircraft through huge geographical ranges don't go even near covering the same distance so rapidly and easily in cultural terms.
We have found ways to move people physically far and fast, but not means to make them change and adapt from one religious, cultural, ideological and social milieu to another at comparable speed.
When a man moves from an Asian or African country to Britain he doesn't magically become a different person.
This has resulted in the strange phenomenon, probably to such large extent peculiar to our age, of people in the same street belonging not only to different parts of the world but to different ages in the history of the world. They are living next door to each other, but at the same time they are not only geographically but also historically light years away from one another.
Mass migration from the Third World to the West has produced the paradox that what was portrayed as a humanitarian gesture – the welcoming of destitute people from poor nations to wealthier countries - has had the effect of spreading some of the globe's worst atrocities far beyond their place of origin.
Shocking examples are the Muslim persecution of Christians now imported to Western asylum centres, and the analogous importation of the Islamic practices of paedophilia and sex slavery - in one third of all marriages celebrated in Pakistan the bride is underage - to Rotherham, Oxford and Rochdale.
