The analogy of oblique sunbeams and the antithesis of a woman's desire to please versus the emotions of jealousy or vanity both contribute to strengthening Wollstonecraft's counterargument against prioritizing the art of pleasing in marriage. These rhetorical devices serve to illustrate the limitations and potential negative consequences of relying solely on external attractiveness and pleasing others for a woman's happiness and fulfillment.
In the given lines, an example of analogy can be found in the comparison between a woman's charms and oblique sunbeams. This analogy strengthens Wollstonecraft's counterargument by suggesting that a woman who has only been taught to please will eventually realize that her charms, like oblique sunbeams, lose their effectiveness when seen every day. It emphasizes the fleeting nature of relying solely on external attractiveness or pleasing others, thereby reinforcing Wollstonecraft's argument against prioritizing the art of pleasing in marriage.
Furthermore, an example of antithesis can be seen in the contrast between a woman's desire to please her husband and the emotions of jealousy or vanity that may arise when the husband ceases to be a lover. This antithesis strengthens Wollstonecraft's counterargument by presenting opposing ideas and contrasting the potential consequences of a woman's sole focus on pleasing her husband. It highlights the possibility that when a husband's love diminishes, a woman's desire to please may turn into bitterness or be replaced by negative emotions such as jealousy or vanity. This reinforces Wollstonecraft's argument that the pursuit of pleasing others can lead to unhappiness and a loss of self-worth.
