Core Theme: Spiritual vs. Physical Existence
At its heart, Sonnet 146 grapples with the conflict between the fleeting physical world and the enduring spiritual self. The speaker addresses their own body as a decaying vessel, urging it to prioritize internal richness over external vanity. This theme ties to broader Renaissance ideas about memento mori (remembering death) and the value of spiritual growth over material comfort. For essay prompts, connect this theme to Shakespeare’s other late sonnets, which often focus on mortality.
