Most of what I encounter is people trying to talk about precise things dependent upon reason and deduction, while relying on imprecise language from which reason and deduction are largely impossible.

One cannot make deductive arguments from the common speech – which is full of error and ignorance.

There is a very good reason that each discipline uses specific terminoligy despite the confusion that this creates for non-members: some degree of precision is necessary for the purpose of argument.

Law still uses latin terms for good reason: they’re not open to colloquial interpretation.
