Lust, that state commonly known as ‘being in love’, is a kind of madness. It is a distortion of reality so remarkable that it should, by rights, enable most of us to understand the other forms of lunacy with the sympathy of fellow-sufferers. And yet as we all know, it is a madness that, however ferocious, seldom, if ever, lasts. Nor, contrary to the popular teaching on the subject, does lust usually give way to a ‘deeper and more meaningful love’.
