I have good reason to be content, for thank God I can read and perhaps understand Shakespeare to his depths.

Keats frames literacy and deep imaginative comprehension as a sufficient ground for gratitude and “content.” The emphasis is not merely on reading Shakespeare, but on penetrating “to his depths”—suggesting that true richness lies in interpretive power and inward access to great art rather than in external success or status. The line also reflects Keats’s characteristic reverence for Shakespeare as a model of poetic genius and capacious human understanding. By thanking God for this capacity, he casts aesthetic insight as a kind of providential gift: the ability to enter Shakespeare’s world becomes a spiritual and emotional resource that can steady him amid uncertainty.
