Level 1: Means Response “A Means Response to a how-possible question regards the identification of one or more of the means by which something can come about as a means of explaining how it is possible. So, for example, if perceiving is a means of coming to know something about the world around us then it is also a means by which knowledge of the external world is possible.” (Cassam 2007: 6)
Level 2: Obstacle Removing Level IObstacle-Overcoming Response: An obstacle-overcoming response would be one which shows that the requirement which is an obstacle to answering a How-Possible Question (HPQ)canin fact be met. IObstacle-Dissipating Response: “An obstacle-dissipating response, in contrast, would be one which makes it plausible that there is no such requirement.” (Cassam 2007: 8)

Level 3: Enabling Conditions IWhat makes it possible for us to acquire knowledge of kind K by means M? “This is a question about what might be called theenabling conditionsof [knowledge of kind K], the conditions under which it is possible for [M] to be a source of knowledge of [kind K] . . . I thought that underpins this question is that there is. . . The more to explaining how something is possible than showing that it isn’t impossible.” (Cassam 2007: 9)

What does a Multi-Levels Response look like? “A multi-levels response to a how-possible question operates on different levels. Level 1 is the level of means, the level at which means of knowing about a certain subject matter are identified. (. . . )Level 2 is the obstacle-removing level, the level at which obstacles to the acquisition of knowledge by the proposed means are overcome or dissipated. Finally, Level 3 is the level at which enabling conditions for knowing by the proposed means are identified.”(Cassam 2007: 10)
