Your theory about how judges should act only makes sense if evaluating arguments is free. But evaluating arguments -- especially unconventional ones -- is really expensive! There is significant cost associated with evaluating an "out there" legal theory (in terms of research, opinion writing, etc.); it's entirely reasonable for judges to not invest public time/money into a point-by-point analysis of an unorthodox legal theory, especially if that theory comes from someone without formal training. Most professionals know that certain non-professionals are capable of doing their jobs, but also know that in the general case hubris is far more common than untrained competence. The parent's point was essentially this -- it's not impossible to represent yourself, but it's much harder than most people realize. Most judges aren't willing to invest the time necessary to investigate/help articulate apparently crazy legal theories, and that's both rational and justified. Explaining point-by-point why a crazy legal theory is crazy is not a good use of public time and money. > Formal logic logic as far as reasoning about non-mathematical subjects is probably not that far from where it was in Aristotle's days. That's my point -- typically "formal logic" means exactly deductions in/about formal systems. Wikipedia redirects "formal logic" to "mathematical logic". Law has no formal logic, and (edit: a lot of) what's taught in law school pre-dates the advent of formal logic (late 1800s) by a hundred years. The ability to prove soundness or completeness or first order logic (the sort of thing I would expect to appear in an introduction to formal logic course) is really completely irrelevant to the practice of law. > the authors considered to be authorities Jurisprudence are, I think, very well informed in formal logic This is simply not true, or else you have an uncommon definition of "formal logic".
