Question

What do you think of the following solution?
First of all, we need to distinguish between a natural desire (craving) and a desire to want (a true desire). If we go back to the example of the diet and the cake, let’s say that the person wants (craves) the cake, but he wants to want to diet. The difference is that it makes sense to say that he does not want to want to eat the cake; that is, for example, he would agree to take a pill that would cause him to stop wanting to eat cake, but clearly he would not agree to take a pill that would cause him to stop wanting to diet.
The desire to want can become a plain desire through the exercise of free choice. To the extent that a person decides, through free choice, to invest more mental effort, he can turn the desire to want into a greater plain desire.
If the person succeeds in translating the desire to want into a desire that is “stronger” than his desire for craving, then he will act according to what he sees as right.
As for Donald Davidson’s arguments, let us say the following:
– A person has a true desire to do what he sees as right, where what he sees as right is determined according to all considerations except cravings.
 – A person exerts mental effort in order to turn a true desire into a plain desire
– The person will act according to his refined desire, which equals the desire that is the result of applying mental effort to the true desire, minus the natural desire
– There is weakness of will when the person did not exert enough mental effort to overcome the craving
