Affection is an important issue both for philosophers and psychologists. In this concise manuscript, Mahmoud Khatami provides philosophical preliminaries for a theory of affection and, very specifically, of love as an affective quality of human life. The book starts with a discussion on the relation of desire, volition and cogitation (Chapter One) which prepares a definition of affection and its classification (Chapter Two), then the subjective aspect of affection is analyzed in more detail (Chapters Three and Four), and then love will be treated as the deepest subjective affection (Chapter Five).
