Guile, often referred to as cunning, is the ability to achieve goals through cleverness and deceit. It involves using intelligence and strategic thinking to manipulate situations or people to one's advantage. This trait can be seen in various contexts, from everyday interactions to complex negotiations. In literature and history, characters known for their guile often outsmart opponents or navigate challenging circumstances. For example, Odysseus from Homer's Odyssey is celebrated for his cunning strategies, which help him overcome obstacles during his journey home. Guile can be both a positive and negative trait, depending on the intent behind its use.
