From the first smouldering taper to the elegant lanterns whose light reverberated around eighteenth-century courtyards and from the mild radiance of these lanterns to the unearthly glow of the sodium lanterns that line the Belgian motorways, it has all been combustion. Combustion is the hidden principle behind every artefact we create. The making of a fish-hook, manufacture of a china cup, or production of a television programme, all depend on the same process of combustion. Like our bodies and like our desires, the machines we have devised are possessed of a heart which is slowly reduced to embers. From the earliest of times, human civilization has been no more than a strange luminescence growing more intense by the hour of which no one can say when it will begin to wane and when it will fade away. For the time being, our cities still shine through the night, and the fires still spread. In Italy, France and Spain, in Hungary, Poland and Lithuania, in Canada and California, summer fires consume whole forests, not to mention the great conflagration in the tropics that is never extinguished.
