Traditional Square of Opposition, Part 1: Supposing only that
the numbered
statements below are true and that they are understood under the
traditional
interpretation (with existential import), what can you say about
the truth-values of
the lettered statements? If you can determine the truth-value, do
so by circling the
appropriate letter: ‘T’ if the statement is true and ‘F’ if the
statement is false. If
you cannot determine the statement’s truth-value, circle ‘I’ for
‘indeterminate.’
