“From the first smouldering taper to the elegant lanterns whose light reverberated around eighteenth-century courtyards and from the mild radiance of those lanterns to the unearthly glow of the sodium lamps 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.”
