“Why doesn't all this information-processing go on "in the dark", free of any inner feel? …We know that conscious experience does arise when these functions are performed, but the very fact that it arises is the central mystery. There is an explanatory gap [a term due to J. Levine, "Materialism and qualia: The explanatory gap" Pacific Philosophical Quarterly 64:354-61, 1983] between the functions and experience, and we need an explanatory bridge to cross it.”

Living Under Tension (1941)
Context: No horse gets anywhere until he is harnessed. No stream or gas drives anything until it is confined. No Niagara is ever turned into light and power until it is tunneled. No life ever grows great until it is focused, dedicated, disciplined. One of the widest gaps in human experience is the gap between what we say we want to be and our willingness to discipline ourselves to get there.

As quoted in "Eccles' Model of the Self Controlling Its Brain : The Irrelevance of Dualist-Interactionism" (2003) by Donald E. Watson and Bernard O. Williams http://www.enformy.com/$dual.html
Context: In order that a "self" may exist there must be some continuity of mental experiences and, particularly, continuity bridging gaps of unconsciousness. For example, the continuity of our "self" is resumed after sleep, anaesthesia, and the temporary amnesias of concussion and convulsions.
