Final answer:
Kant's approach to morality does not build upon Locke's theory of unalienable rights.
Step-by-step explanation:
False
Kant's approach to morality does not build upon Locke's theory of unalienable rights. While both philosophers had significant contributions to moral philosophy, they had different perspectives. Locke emphasized natural rights and the idea that individuals have certain rights that cannot be taken away by any authority, including the state. On the other hand, Kant focused on deontological ethics and the categorical imperative, which is the idea that moral actions are based on duties and rational principles.
