As I said, the repetitions are the result partly of the deficient terminology and partly of unfamiliarity with the discipline of logic. It will be very hard to get them all out. If the man absolutely insists on having his things printed I am not sure that to limit him to two printer's sheets would be the best for him in any case it would give him the devil's own job as he is not conscious of his repetitions, and then I am not sure either whether two sheets would get any attention paid them at all. More likely six to eight. And he will never get it into a periodical.
