The relationship between consciousness,understanding, and rationality

The purpose of the present article is to explore the relationship between consciousness and understanding. To do so, I first briefly review recent work on the nature of both understanding and consciousness within philosophy and psychology. Building off of this work, I then defend the thesis that if one is conscious of a given content then one also understands that content. I argue that this conclusion can be drawn from (1) the fact that understanding is associated with rational intention formation and (2) the fact that conscious access appears to involve the selective routing/broadcasting of representational content to neural systems that integrate information in order to select cognitive/behavioral intentions in conjunction with goals. Based on these premises I illustrate how a disruption to the rationality of a representation’s influence on intention formation (when it becomes consciously accessible) would also remove any evidence that a person was conscious of the content of that representation. I therefore suggest that conscious content (and associated phenomenology) may be determined by the rational, content-appropriate influences an accessed representation has on intention formation (i.e., the influences associated with understanding). I conclude by offering replies to several potential objections to this thesis.
