Final Summer 98
Intro to Logic; Professor Bringsjord
Due by 5pm 6/26; disk under my office door
- Take the post-test in class Thu 6/25. This is required as per the
agreement you signed at the outset of the course; no grade will be submitted
without this test being completed at the scheduled time (again, start of
class 6/25). Thanks!
- Create and turn in your own Hyperproof problem.
- Solve the following two problems in Hyperproof; turn in the resultant
file. (One file with obvious predicates will do. For problems
that don't require a proof of non-consequence, I
I encourage you not
to use the visual side of Hyperproof.
Simply dream up your own new predicates having just one letter. For
example, to represent 'All Bulls are cocky' you might
say 'Vx (B(x) -> C(x))'.)
In each of these two problems you are given a set of premises, which
you can assume to be true. You are then asked whether or not a
pair or trio of other
propositions (the ones coming after 'Therefore')
follow logically (i.e., are derivable in Hyperproof). Your answer
should be a yes or a no for each of these two propositions.
- Some tennis players are golfers. All golfers are
temperamental. Some temperamental people are brilliant.
Therefore some tennis players are temperamental.
Therefore some golfers are brilliant.
- All Norwegians ski. Norwegians from the
town of Lyngdal don't ski; Norwegians from the North of Norway
do ski. All those who ski are rugged.
Therefore the moon is made of green cheese.
Therefore all Norwegians are rugged.
Therefore no Norwegians are rugged.
- Proof 9.29
- Proof 9.49

Hyperproof Hall of Fame.
