Natural Selection: Principles of Adaptation

Natural selection is the principle that variations in the biology or behavior of a species result in some individuals possessing traits that confer an advantage in survival. This process is highly dependent on the environment.

Individuals with these advantageous traits are more likely to survive, prosper, and reproduce. Over time, the population becomes dominated by individuals exhibiting these beneficial biological or behavioral characteristics. Offspring of the same species can be born with mutations, introducing new variations. Natural selection drives populations to become adapted, or increasingly well-suited, to their environments over time. This process relies on the environment and requires existing...

Marriage in American Literature

Marriage is one of the most prominent themes portrayed in some American literary works, and there are different conceptions of the issue.

Washington Irving

In Rip Van Winkle, the protagonist sees marriage as a punishment and a source of unhappiness. Rip Van Winkle is depicted as a humble person who helps everyone that needs him and who has no evilness inside. However, his relationship with his wife is different.

Symbolism of Settings in The Scarlet Letter

The Scarlet Letter, a historical fiction masterpiece by Nathaniel Hawthorne, uses setting to powerfully connect fact and fiction. The diverse settings, such as the marketplace, the forest, the scaffold, and Hester's cottage, serve as symbols supporting the novel's themes.

The Forest: A Place of Autonomy and Truth

In contrast, the forest is the antithesis of the Puritan world. Here, individuals are autonomous, governed only by their own... Continue reading "Symbolism of Settings in The Scarlet Letter" »

The Failed Hero's Journey in Washington Irving's Rip Van Winkle

Male Flight from Home and Responsibilities into the Wilderness

According to Joseph Campbell, the story of the hero takes place in three stages: withdrawal, initiation, and return. The hero abandons his family or community, undergoes an initiation, which is usually an encounter with supernatural forces, and eventually returns to society, wiser than before.

A closer reading of "Rip Van Winkle" alongside Campbell's work will demonstrate that Irving was well aware of this pattern, and that he both followed and veered from it intentionally for his own purposes.

Withdrawal: Escape from Domestic Strife

As Campbell explains, the hero's story starts with a call to adventure. The hero does not... Continue reading "The Failed Hero's Journey in Washington Irving's Rip Van Winkle" »

Acquisition Campaigns: Acquire New Prospects and Customers
