This chapter argues that while Shakespeare has no single or overarching theory or view of love, specific patterns or tendencies are evident in both the plays and the poems. It focuses on three characteristics of such a disposition: the singularity of the beloved (‘you are you’) that admits of no substitute; the essentially projective rather than reactive vision of love (‘love sees not with the eyes but with the mind’); and the perhaps counterintuitive fact that love is not an emotion as such, but rather a disposition or form of behaviour that involves different, sometimes contradictory, emotions. This puts Shakespeare at odds with contemporary, Galenic theories of love as one of the most volatile of the passions. The Sonnets, for example, are virtually devoid of references to contemporary psychology, and the chapter focusses on these poems to explore the rich varieties of emotion they express in their complex and fraught negotiations of love and desire. Classifying and arranging the sonnets in accordance with the emotions expressed in them furthermore does not accord with the usual narrative attributed to them.
