塞尔和德雷福斯在三个基本问题上有意见分歧。德雷福斯认为,满足条件涉及知觉,而且,行动在通常意义上不需要是命题的。尽管我们通常从事所谓的慎思活动,但如此深思熟虑的活动不是我们与世界相联系的唯一方式,也不是最基本的方式。在有些情况下,行动者根本不是在尝试。存在着身体意向性和作为第三种存在方式的在世存在。 Sale and Dreyfus divided on three basic issues. Dreyfus believes that satisfying conditions involves perceptions, and that actions need not be propositions in the usual sense. Although we usually engage in so-called deliberative activities, such thoughtful activity is not the only way we are linked to the world, nor is it the most basic way. In some cases, actors are not trying at all. Existence of bodily intent and presence as a third way of existence exist.
