Kant deemed that an action was moral if its motive could embody a ‘maxim’ which we could justify if it were a universal law; “Act only according to that maxim whereby you can, at the same time, will that it should become a universal law.” (Groundwork for the Metaphysics of Morals, p.30). Therefore, we act in accordance with a law created through our own reason, making it a truly autonomous act. This means that no moral decision depends on the situation it is in, which would impose external laws on morality. For example, “lying is always wrong” because we cannot allow lying to be a universal law, as it would be immoral for lying to always be acceptable, so there should be no exceptions regardless of if there would be any positive consequences from the lie in a particular situation. Kant’s argument is that, instead of being obedient to an externally imposed law or religious precept, one should be obedient to one’s own self-imposed
