Final answer:
Aristotle's philosophy posits that true happiness, or eudaimonia, requires harmony between reason and emotions; thus, it is true that he likens those out of harmony to bent sticks, as they deviate from virtuous action.
Step-by-step explanation:
True or False: Aristotle maintains that people whose emotions or desires are out of harmony with their reason are like bent sticks. The corresponding statement is true. Aristotle's philosophy is deeply rooted in the idea of virtuous development and eudaimonia, or human flourishing. He argues that virtues are habits of character essential for achieving happiness, and these virtues help us make the right decisions.
If emotions and desires are not aligned with reason, they can lead to wrongful actions, similar to how a bent stick deviates from its intended straight form. Through habituation and practical experience, people can learn to harmonize their emotions with their reason, thus becoming virtuous.
