Logic, "Malarkey? or Effective Way?", and Dogarrhea: Three mostly unrelated topics.
1.
I just got my second logic exam grade: 40/40, plus the additional "makeup" question at the end (worth three possible points). This worries me: I was certain that there were things I didn't understand, like:
- If you only have one premise in an argument, and that premise is true while the conclusion is false, is it an invalid argument when it's truth-tabled? (yes, yes it is, it turns out).
- What is a logical implication? Argh! (Turns out, it's a one-way relationship between two different equations; where A&B implies A, but A&[B-or-C] does not imply if-B-then-C. It does imply A&B and B-or-C, I think).
- In a shortcut truth table, can you replace variables with truth values where it otherwise doesn't matter? (yes, yes you can, like in A-or-B, you can get "true" as long as at least one of the two variables are "true")
Ah, but apparently I did fine. A lot of people had problems forming questions from "unless" and "only if" and sentences that were restructured to have "if" in the middle of the sentence. All it takes, apparently, is a little restructruing (that I caught because I get nervous about these things).
So:
"Bob will get a burger if Sally doesn't get one" (B, S)
would be
~S>B ["If not S(ally will get a burger) then B(ob will get a burger)"]
So, yeah. I almost laughed until I wept when I got my score back. I was told "You suck" by my former boss' theatrically morose daughter, who is in that class with me. I talked to a guy behind me who also got a perfect. Hooray for the front-of-the-room sitters.

Actual Book Title: How to Good-bye Depression: If You Constrict Anus 100 Times Everyday. Malarkey? or Effective Way?
Actual Book Description: I think constricting anus 100 times and denting navel 100 times in succession everyday is effective to good-bye depression and take back youth. You can do so at a boring meeting or in a subway. I have known 70-year-old man who has practiced it for 20 years. As a result, he has good complexion and has grown 20 years younger. His eyes sparkle. He is full of vigor, happiness and joy. He has neither complained nor born a grudge under any circumstance. Furthermore, he can make love three times in succession without drawing out.
In addition, he also can have burned a strong beautiful fire within his abdomen. It can burn out the dirty stickiness of his body, release his immaterial fiber or third attention which has been confined to his stickiness. Then, he can shoot out his immaterial fiber or third attention to an object, concentrate on it and attain happy lucky feeling through the success of concentration.
If you don't know concentration which gives you peculiar pleasure, your life looks like a hell.
WOW

In unrelated news, HANK DOG HAD THE SHITS TODAY.
Katie cleaned up the mess around his kennel, and I got to give him a bath.
Ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew.
Still grossed out by the thought of it. And the smell...you could smell it from the building's entryway.
Ew. Ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew ew.
