'Nicomachean Ethics' is a foundational text in Western philosophy that provides deep insights into ethical virtue, happiness, and practical wisdom, making it essential for students of philosophy and ethics.

'Nicomachean Ethics' is known for being dense and complex, which can make it challenging for readers. In contrast, 'Why We Sleep' is generally more accessible and aimed at a broader audience interested in understanding sleep. Therefore, 'Nicomachean Ethics' is typically considered more challenging to read than 'Why We Sleep'.
