The question was rhetorical. As a man totally without pride, Senator McCarthy never ascended to the level of a man capable of shame. What Senator McCarthy, and all too many people of his stripe, have had in abundance is hubris. I have no doubt that, having been honored with a seat in the Senate, and having used that position to make himself feared by many far better men and women, McCarthy felt that he had grounds for pride, but he had not. All he had was hubris.
Pride is personal and it is internal.
Hubris is something else. Hubris is the value I place upon myself because of acknowledgements or honors I receive. It is a high grade point, and never mind how you got it. If one basks in admiration, however sincere or however well-intentioned, which one receives from others, that is hubris. If one achieves distinction by undiscovered cheating, one builds hubris, and shame.
