Throughout The Good Soldier, Leonora Ashburnham and Florence Dowell are presented as foils to each other. Each woman represents an opposing end of the novel’s moral spectrum, although their relative goodness or badness doesn't necessarily reflect how the narrator feels about them at any given time. The difference in how John Dowell speaks about Leonora and Florence is an important aspect of his role as an unreliable narrator.
The motif of the date "August 4" appears regularly in The Good Soldier, pointing to the fragmented structure of the narrative. It’s depicted as being an important milestone in Florence’s life on many occasions, as the unreliable John tells the reader:
Unlock with LitCharts A+It is, however, certain that the 4th of August always proved a significant date for her. To begin with, she was born on the 4th of August. Then, on that date [..] she set out with her uncle for the tour round the world [...] Then, on the 4th of August, 1900, she yielded to an action that certainly coloured her whole life [...] On the 4th of August, 1901, she married me, and set sail for Europe [...]
Towards the end of Part 3, the narrator delves into Leonora and Edward’s past and describes the circumstances that led to their wedding. In doing so, Ford employs situational irony as John dismisses the need for a “minute study” of the marriage:
