Committal

On reading the work, we have become impressed with this fact, and have several times wished that the author was more committal on the treatment of several diseases in which he himself must have had a large experience.

He points out that the former hypothesis is less committal epistemically, and he claims that nothing more committal is required to make sense of scientific method.

Notice also that the credibility of noncommittal observational beliefs will compare in a similar way with the credibility of more committal (or theoretical) observational beliefs, such as belief that addition of a base solution to an acid solution (to take the more committal, or theoretical, version of the noncommittal observational belief just mentioned).
