[Let us take, as examples, the results of the four Examples worked in the previous Chapters.
(1) ·---------------· |(O) | (O)| | ·---|---· | | | |(O)| | |---|---|---|---| | | |(O)| | | ·---|---· | | | | ·---------------·
In the N.W. Quarter, only _one_ of the two Cells is marked as _empty_: so we do not know whether the N.W. Quarter of the Biliteral Diagram is _occupied_ or _empty_: so we cannot mark it.
·-------· | |(O)| |---|---| | | | ·-------·
In the N.E. Quarter, we find _two_ "O"s: so _this_ Quarter is certainly _empty_; and we mark it so on the Biliteral Diagram.
In the S.W. Quarter, we have no information _at all_.
In the S.E. Quarter, we have not enough to use.
We may read off the result as "No x are y'", or "No y' are x," whichever we prefer.
(2) ·---------------· | | | | ·---|---· | | |(O)|(I)| | |---|---|---|---| | |(O)| | | | ·---|---· | | | | ·---------------·
In the N.W. Quarter, we have not enough information to use.
In the N.E. Quarter, we find a "I". This shows us that it is _occupied_: so we may mark the N.E. Quarter on the Biliteral Diagram with a "I".
·-------· | |(I)| |---|---| | | | ·-------·
In the S.W. Quarter, we have not enough information to use.
In the S.E. Quarter, we have none at all.
We may read off the result as "Some x are y'", or "Some y' are x", whichever we prefer. pg055 (3) ·---------------· | | | | ·---|---· | | | |(O)| | |---|(I)|---|---| | | |(O)| | | ·---|---· | |(O) | (O)| ·---------------·
In the N.W. Quarter, we have _no_ information. (The "I", sitting on the fence, is of no use to us until we know on _which_ side he means to jump down!)
In the N.E. Quarter, we have not enough information to use.
·-------· | | | |---|---| | |(O)| ·-------·
The S.E. Quarter is the only one that yields enough information to use. It is certainly _empty_: so we mark it as such on the Biliteral Diagram.
We may read off the results as "No x' are y'", or "No y' are x'", whichever we prefer.
(4) ·---------------· |(O) | | | ·---|---· | | |(I)| | | |---|---|---|---| | |(O)|(O)| | | ·---|---· | |(O) | | ·---------------·
The N.W. Quarter is _occupied_, in spite of the "O" in the Outer Cell. So we mark it with a "I" on the Biliteral Diagram.
