Some art forms welcome, even require, collaboration. After all, it is the exceptionally rare film or television show that gets made by a single person. Music, too, often literally demands the assistance of others.
A half-formed thought feels worse than an empty head—the tip-of-the-tongue sensation, the inkling of a there there without the foggiest notion of how to get, well, there. Especially dire is when the “what” that we wish to articulate feels half-formed itself, something observable yet emergent, for which the masses have yet to find language.
