A defense is different from an otherwise acceptable activity because a defense is used to get away from what it feels like to be us or to avoid the emotion that is trying to get our attention. A defense isn’t necessarily a bad thing; sometimes it’s too much of a good thing, or sometimes we’re using an otherwise good thing to get away from feeling something. Having a glass of wine to get away from our feelings is different from having a glass of wine because it complements the meal. The same is true of learning, laughter, and eating.
