but this is nonsense, as the top line, {{nowrap|"T T F,"}} gives the proposition all greater logical multiplicity than that of the actual possibilities. It is, of course, a deficiency of our (171) notation that it does not prevent the formation of such nonsensical constructions, and a perfect notation will have to exclude such structures by definite rules of syntax. These will have to tell us that in the case of certain kinds of atomic propositions described in terms of definite symbolic features certain combinations of the T's and F's must be left out. Such rules, however, cannot be laid down until we have actually reached the ultimate analysis of the phenomena in question. This, as we all know, has not yet been achieved.
