Final answer:
Kant argues that it is impossible to treat others as both a means and an end. We should treat others as ends-in-themselves, recognizing their inherent value and worth as rational beings.
Step-by-step explanation:
Kant argues that it is impossible to treat others as both a means and an end. He believes that we should treat others as ends-in-themselves, as rational beings, rather than using them as mere tools to achieve our goals. By treating others as ends, we recognize their inherent value and worth as rational beings. This means that we cannot use other people as instruments to fulfill our own desires or objectives. Kant's ethical philosophy emphasizes the importance of respecting the autonomy and dignity of every individual.
