Fluidity is the ease by which knowledge, the deep knowledge of the expert, is translated among people and machines, to good purpose. Fluidity presumes the elimination of barriers of all kinds.

Information technology models presume the need for intermediaries between people and the systematic application of their knowledge. There is little scientific justification for this presumption, but old habits die hard.

The question of fluidity resides in making knowledge forms available when they are needed. This presupposes an electronic system of some kind to support the distribution of such knowledge forms. This is not to say that current models for identifying and distributing such knowledge forms when they are needed are optimal. Rather, the Profundities message is that there are superior methods that are little utilized. Chief among these is the expressive knowledge form, which is a means of converting expertise and documentation to process forms, where they can be readily used.

When correct answers are readily available by means of an available system, its use is pretty self-explanatory. The question is in how to recruit and enlist the support of the experts themselves. We have made some progress in this area, but there much to be learned still in carrying out such a process.

Was Beethoven recruited to a career in music composition? He did begin at an early age. How was Johann Sebastian Bach brought along in music? For one thing, he benefited from the excellent Lutheran musical tradition. Our challenge is to encourage such a system and society in our day.
