I think that is intended by Tolstoy. He gives the following extreme example > A drunken man is ashamed of none of these things, and therefore if a man wishes to do something his conscience condemns he stupefies himself. Stupefies is a negative term because he is against alcohol but socialising is easier because of exact same reason. It removes the filter and we could do things which we are "ashamed" of, even if there is nothing to be ashamed of. e.g. I am ashamed of talking to stranger or discussing details of my life when sober.
