Watch this lecture until 22:29. As you watch, consider whether you you agree with Kant's belief that it is never morally permissible to lie. Kant's idea that duty and autonomy are compatible seems to be counter-intuitive. In this lecture, Sandel helps us make sense of this view, and applies it to the example of lying. Ordinarily, many of us believe that lying is never morally permissible, unless doing so will help avert a greater harm. Kant famously denies this view. He asserts that even if we believe a great harm will result from our failure to lie, the lie is immoral because it means we will have failed to respect a moral law that springs from our rationality.
