FORM OR SUBSTANCE?

The question of form vs substance continues to present itself in many practical situations. To be effective, a good solution must include both. Form without substance is superficial; substance without form may fall short of engaging the audience. In either case, the point is likely to be lost.

In July 1996, I attended a one-day workshop convened in Santa Cruz de la Sierra, Bolivia, to examine the environmental impact of the Parana-Paraguay waterway on the Pantanal of Mato Grosso. The day before the conference, I had dinner in La Paz with a colleague, who was to present his work at the workshop. Among other topics, we discussed the subject of free-surface instability. I came away from the meeting greatly impressed by his technical grasp of the subject.

Later that day, we traveled to Santa Cruz de la Sierra, where the workshop was to take place the following day. My colleague's presentation was highly technical, and it was delivered in a soft and monotonous tone. When my turn came, I summarized the findings of my 1995 study on the hydrologic and environmental impact of the Parana-Paraguay waterway on the Pantanal of Mato Grosso.

The last presentation of the day was by a person who spoke in a very clear and engaging manner. Pleasantly surprised, and seeing that his style was quite different from what I had observed before, I was curious to find out what his background was. His answer was: "Communications." That explained it, but I could not help but wonder whether we had again been caught in the age-old predicament between form and substance.
