A currently popular joke takes this form: someone returns to his or her residence after doing an errand and announces: "I have good news and bad news." The good news is usually very good (for example, the messenger has just won a lottery), but then the bad news is usually equally as bad (s/he has subsequently lost the money gambling, or down a sewer). In some respects my overall evaluation of Marx's theories of human nature takes this form, except that the bad news is not always as bad as the good is good, and the process of evaluation is not intended to be, nor, hopefully, will be taken as, a joke.
