Allen Wood gives 4 different statements regarding Kant's moral theory, specifically regarding categorical imperatives:
1. Categorical imperatives are supposed to be unconditionally valid. Therefore, any principle! that is seen as a categorical imperative (for example, 'Do not lie') must be viewed inflexibly as having no exceptions whatever.
2. But it does not imply that the obligation to keep promises might not be conditional in other Ways - for instance, that this obligation might cease to exist if
keeping the promise would somehow violate the dignity of humanity or if we knew that the person promised would release us from the promise if they knew of the unforeseen situation in which we find ourselves when it comes time to keep it.
3. When we have good and sufficient grounds to make exceptions to a moral rule, this means only that the rule (under those circumstances) no longer binds us categorically (or, indeed, in any other way). Thus whether there are any moral rules at all that hold without exceptions is not decided by accepting Kant's claim that all moral obligations involve categorical imperatives.
4. Human dignity is also seen as providing reasonable grounds for making exceptions to moral
rules against lying or suicide in certain cases.
There seems to be a rather subtle argument being made that I imagine I'm not quite competent to grasp. On the one hand, no exceptions are to be made regarding categorical imperatives (beyond the release of our promise by that person we made the promise to, thus removing the possibility of exception by removing the situation where the potential to break the imperative is possible), while on the other we're given the right to break certain imperatives for the state of human dignity. I was interested of what others made of this thread within the paper? Perhaps clarify how these aspects of Kant's theory fit together?
