Sleep well, father. E-prime provides linguistic, not mathematical discipline. If you don't want to follow the link, that means: "In essence, E-Prime consists of a more descriptive and extensionally oriented derivative of English, that automatically tends to bring the user back to the level of first person experience." It works its magic by eliminating all forms of the verb "to be" from speech, written and spoken.
I find this hard to do, but notice that the above blog entry contains no such structures. Of course, my training in Russian gives me a leg up because the Russian language lacks a present tense form of that verb. So I worked without it regularly in my youth.
