There is even a happiness - that makes the heart afraid.

Hood’s line captures a paradox: some joys arrive with an undertow of dread. Happiness can feel precarious—so intense, so unexpected, or so hard-won that it awakens fear of loss, reversal, or unworthiness. The “afraid” heart suggests emotional self-protection: when one has known disappointment, grief, or instability, even genuine delight can trigger anxiety, as if it tempts fate or cannot last. In this sense the quote speaks to the psychological complexity of pleasure, where anticipation and memory shadow the present. It also reflects a Romantic-era sensitivity to mixed emotions, emphasizing that human feeling rarely comes in pure, uncomplicated forms.
