Here's a clue. It's from Lewis Carroll's "Symbolic Logic" http://www.gutenberg.org/2/8/6/9/28696/ (4) "Of the prisoners who were put on their trial at the last Assizes, all, against whom the verdict 'guilty' was returned, were sentenced to imprisonment; Some, who were sentenced to imprisonment, were also sentenced to hard labour". Let Univ. be "the prisoners who were put on their trial at the last Assizes"; m = who were sentenced to imprisonment; x = against whom the verdict 'guilty' was returned; y = who were sentenced to hard labour. The Premisses, translated into abstract form, are "All x are m; Some m are y". Breaking up the first, we get the three (1) "Some x are m; (2) No x are m'; (3) Some m are y". Representing these, in the order 2, 1, 3, on a Triliteral Diagram, we get ·---------------· |(O) | (O)| | ·---|---· | | | (I) | | |---|(I)|---|---| | | | | | | ·---|---· | | | | ·---------------· Here we get no Conclusion at all. You would very likely have guessed, if you had seen _only_ the Premisses, that the Conclusion would be "Some, against whom the verdict 'guilty' was returned, were sentenced to hard labour". But this Conclusion is not even _true_, with regard to the Assizes I have here invented.
