The language we use when we are in love is not a language we speak, for it is addressed to ourselves and to our imaginary beloved. It is a language of solitude, of mythology, of what Barthes calls an 'image repertoire'.

This book revives - beyond the psychological or clinical enterprises which have characterised such researches in our culture - the notion of the amorous subject. It will be enjoyed and understood by two groups of readers: those who have been in love (or think they have, which is the same thing), and those who have never been in love (or think they have not, which is the same thing). This book might be considered, in its restless search for authorities and examples, which range from Nietzsche to Zen, from Ruysbroek to Debussy, an encyclopaedia of that affirmative discourse which is the lover's.
