Another difference between moral and legal rules is that moral rules cannot be changed with the ease that legal rules can be. Rules that are inculcated are not subject to alteration in the shon run, it will often Lake least a generation to accomplish that. However, a qualification to disp is that, to the extent that moral rules are of a general nature, it may be possible to change their specific interpretation fairly quickly For instance, the broad moral principle that it is good to help the disadvantaged might be harnessed in a short time by a moral entrepreneur to make people think it right to help the homeless, as these individuals might be said to exemplify the disadvantaged. In any case, subject to the qualification just mentioned, moral rules appear to be much less malleable than legal rules,
