It's virtually impossible to have a deep design-related discussion without it sounding to naive ears as pretentious. Design is the art of arranging things so as to evoke particular feelings in people. To discuss them is to discuss the feelings they're evoking vs the feelings that were intended to be evoked. And there's only so far you can get with the sorts of words ordinary people use to talk about their feelings. And nobody likes to hear that other people might feel and perceive deeper than them.
