Tom is imprisoned in the Fleet Prison in London, surrounded by evidence of his failure. He attempts to devise inventions and plans to escape debt, while Sarah Young visits in visible distress. The chaotic interior, filled with discarded projects and creditors, reflects mental as well as financial collapse. This plate represents a moment of psychological disintegration where hope becomes delusion and social failure becomes irrevocably public.
Here we learn that a happy person can look back on their lives and remember all the good they have done which will bring comfort in old age. But a guilt person only has regrets and thinks about their past wrongs which brings despair and disturbs the mind:

"Happy the man, whose constant thought (Though in the school of hardship taught,) Can send Remembrance back, to fetch Treasures from life's earliest stretch; Who, self-approving, can review Scenes of past virtues, which shine through The gloom of age, and cast a ray To gild the evening of his day! Not so the guilty wretch confin'd; No pleasures meet his conscious mind; No blessings brought from early youth, But broken faith, and wrested truth, Talents idle and unus'd, And ev'ry trust of heav'n abus'd. In seas of sad reflection lost, From horrors still to horrors toss'd, Reason the vessel leaves to steer, And gives the helm to mad despair".
