Final answer:
Kant's deontological approach focusing on categorical imperatives is distinct from Locke's theory of natural rights, so the statement that Kant built his moral philosophy on Locke's theory of unalienable rights is false.
Step-by-step explanation:
Kant's approach to morality does not build upon Locke's theory of unalienable rights, which makes the assertion that Kant's ethical framework arises from Locke's theory false. Instead, Kant developed a deontological approach to ethics, focusing on duties and rules that rational beings should follow, called categorical imperatives. In contrast, John Locke emphasized natural rights in a state of nature, advocating for life, liberty, and property, which Thomas Jefferson drew from when drafting the Declaration of Independence, as reflected in the concept of life, liberty, and the pursuit of happiness.
