As a general rule of biology, migratory species are less 'aggressive' than sedentary ones. There is one obvious reason why this should be so. The migration itself, like the pilgrimage, is the hard journey: a 'leveller' on which the 'fit' survive and stragglers fall by the wayside. The journey thus pre-empts the need for hierarchies and shows of dominance. The 'dictators' of the animal kingdom are those who live in an ambience of plenty. The anarchists, as always, are the 'gentlemen of the road'.

And when you look along the way we've come, there are spirals of vultures wheeling.

A journey is a fragment of Hell.

I climbed a path and from the top looked up-stream towards Chile. I could see the river, glinting and sliding through the bone-white cliffs with strips of emerald cultivation either side. Away from the cliffs was the desert. There was no sound but the wind, whirring through thorns and whistling through dead grass, and no other sign of life but a hawk, and a black beetle easing over white stones.

I never liked Jules Verne, believing that the real was always more fantastic than the fantastical.

I slept in black tents, blue tents, skin tents, yurts of felt and windbreaks of thorns. One night, caught in a sandstorm in the Western Sahara, I understood Muhammed's dictum, 'A journey is a fragment of Hell.'

Sluggish and sedentary peoples, such as the Ancient Egyptians-- with their concept of an afterlife journey through the Field of Reeds-- project on to the next world the journeys they failed to make in this one.
