Logic

Content:

Faulty Logic

Logic is based on how one assesses the situation and makes decisions based on the assessment. You have heard the saying: "Be careful for what you ask for!" "You might get it!" This often times is the case when our logic is faulty. We think we really will be better off if we get... or when we get older and we are able to do... or if only if we could have... and then our lives would be perfect, wholesome, healthy, and exemplary. Hmm. Check out the results of such thinking based on faulty logic in the following examples.

What a Gift!

Dear Diary... For my fiftieth birthday this year, my husband (the dear) purchased a week of personal training at the local health club for me. Although I am still in great shape since playing on my high school softball team, I decided it would be a good idea to go ahead and give it a try. I called the club and made my reservations with a personal trainer I'll call Bruce, who identified himself as a 26-year-old aerobics instructor and model for athletic clothing and swim wear. My husband seemed pleased with my enthusiasm to get started. The club encouraged me to keep a diary to chart my progress.

Monday: Started my day at 6:00 am. Tough to get out of bed, but found it was well worth it when I arrived at the health club to find Bruce waiting for me. He is something – with blond hair, dancing eyes and a dazzling white smile. Woo Hoo!! Bruce gave me a tour and showed me the machines. He took my pulse after five minutes on the treadmill. He was alarmed that my pulse was so fast, but I attribute it to standing next to him in his Lycra aerobic outfit. I enjoyed watching the skillful way in which he conducted his aerobics class after my workout today. Very inspiring. Bruce was encouraging as I did my sit-ups, although my gut was already aching from holding it in the whole time he was around. This is going to be a FANTASTIC week!!

Tuesday: I drank a whole pot of coffee, but I finally made it out the door. Bruce made me lie on the floor and push a heavy iron bar into the air - then he put weights on it! My legs were a little wobbly on the treadmill, but I made the full mile. Bruce's rewarding smile made it all worthwhile. I feel GREAT!! It's a whole new life for me.

Wednesday: The only way I can brush my teeth is by lying on the toothbrush on the counter and moving my mouth back and forth over it. I believe I have a hernia in both pectorals. Driving was OK as long as I didn't try to steer or stop. I parked on top of a GEO in the club parking lot. Bruce was impatient with me, insisting that my screams bothered other club members. His voice is a little too perky for early in the morning and when he scolds, he gets this nasally whine that is VERY annoying. My chest hurt when I got on the treadmill, so Bruce put me on the stair monster. Why the heck would anyone invent a machine to simulate an activity rendered obsolete by elevators! Bruce told me it would help me get in shape and enjoy life. He said some other crap too.

Thursday: Bruce was waiting for me with his vampire-like teeth exposed as his thin, cruel lips were pulled back in a full snarl. I couldn't help being a half an hour late; it took me that long to tie my shoes. Bruce took me to work out with dumbbells. When he was not looking, I ran and hid in the men's room. He sent Lars to find me, then, as punishment, put me on the rowing machine - which I sank.

Friday: I hate that Bruce more than any human being has ever hated any other human being in the history of the world. He is a stupid, skinny, anemic little cheerleader wanna-be jerk. If there were a part of my body I could move without unbearable pain, I would beat him with it. Bruce wanted me to work on my triceps. I don't have any triceps! And if you don't want dents in the floor, don't hand me the stupid barbells or anything that weighs more than a sandwich. (Which I am sure you learned in the sadist school you attended and graduated magna cum laude from, you Nazi Sadist!) The treadmill flung me off and I landed on a health and nutrition teacher. Why couldn't it have been someone softer, like the drama coach or the choir director?

Saturday: Bruce left a message on my answering machine in his grating, shrilly voice wondering why I did not show up today. Just hearing him made me want to smash the machine with my planner. However, I lacked the strength to even use the TV remote and ended up watching eleven straight hours of the Weather Channel.

Sunday: I'm having the Church van pick me up for services today so I can go and thank GOD that this week is over. I will also pray that next year my husband (the ingrate) will choose a gift for me that is fun - like a root canal or a hysterectomy.

    

Senior Logic

At a nursing home in Miami, Florida, a group of Senior Citizens were sitting  around talking about their ailments: 

"My arms are so weak I can hardly lift this cup of coffee," said one. "Yes, I know. My cataracts are so bad I can't even see my coffee," replied another. "I can't turn my head because of the arthritis in my neck," said a third,  to which several nodded weakly in agreement.  "My blood pressure pills make me dizzy,".... another went on. "I guess that's the price we pay for getting old," winced an old man as he slowly shook his head. Then! there was a short moment of silence.......... 

 "Well, it's not that bad," said one woman cheerfully. "Thank God we can all still drive!"

Logical Conclusions 

Often times, when dealing with problems or conflicts people want to see research data to validate positions taken on issues. Over dependency on "facts and figures" can sometimes stymie, paralyze, or sabotage the critical thinking process. What can happen is "Paralysis by Analysis." However, there are other times when numbers do count, especially when you are "feeling sorry for yourself," believing that your life is a "waste", or "why does everybody else have it better than me?" To help you think critically when you get yourself into a self-pitying position use these next items to set you straight.

Listen Up!

  • Near to the door

  • he paused to stand

  • as he took his class ring

  • off her hand

  • all who were watching

  • did not speak

  • as a silent tear

  • ran down his cheek

  • and through his mind

  • the memories ran

  • of the moments they walked

  • and ran in the sand (hand and hand)

  • but now her eyes were so terribly cold

  • for he would never again

  • have her to hold

  • they watched in silence

  • as he bent near

  • and whispered the words...

  • "I LOVE YOU" in her ear

  • he touched her face and started to cry

  • as he put on his ring and wanted to die

  • and just then the wind began to blow

  • as they lowered her casket

  • into the snow...

  • this is what happens

  • to man alive...

  • when friends let friends...

  • drink and drive.

I received this message from a former student who wrote: "My best friend died my senior year in a car crash, she had been drinking." Even though people know the numbers of death each year which result from drinking and driving, they still take the risk to do so, thinking those numbers will never catch up with them...

These Numbers Add Up 

If earth's population was shrunk into a village of just 100 people with all the human ratios existing in the world still remaining what would this tiny, diverse village look like?

That's exactly what Phillip M. Harter, a medical doctor at the Stanford University School of Medicine, attempted to figure out.  This is what he found.:

57 would be Asian
21 would be European
14 would be from the Western Hemisphere
8 would be African
52 would be female;
48 would be male
70 would be nonwhite;
30 would be white
70 would be non-Christian;
30 would be Christian
89 would be heterosexual;
11 would be homosexual
6 people would possess 59 percent of the entire world's wealth, and all
    6 would be from the United States.
80 would live in substandard housing
70 would be unable to read
50 would suffer from malnutrition
1 would be near death
1 would be pregnant
1 would have a college education
1 would own a computer

When one considers our world from such a compressed perspective, the need for acceptance, understanding and education becomes glaringly apparent. 

The following is also something to ponder... 

If you woke up this morning with more health than illness... you are more blessed than the million who will not survive this week. 

If you have never experienced the danger of battle, the loneliness of imprisonment, the agony of torture, or the pangs of starvation ...you are ahead of 500 million people in the world.

If you can attend a church meeting without fear of harassment, arrest, torture, or death...you are more blessed than three billion people in the world.

If you have food in the refrigerator, clothes on your back, a roof overhead and a place to sleep...you are richer than 75% of this world. If you have money in the bank, in your wallet, and spare change in a dish someplace ... you are among the top 8% of the world's wealthy.

If your parents are still alive and still married ... you are very  rare, even in the United States and Canada.

If you can read this message you are more  blessed than over two billion people in the world that cannot read at all.


Do not Ignore the Obvious in Using Your Logical Reasoning

It is important to be analytical and use good rational logic in solving problems, making decisions, and resolving conflicts, but do not leave out the obvious evidence present to your senses. It is imperative that you use all of your senses (sight, sound, smell, touch, taste) when assessing the problems, situations or issues which confront you. Do not ignore the obvious signs which bombard your senses when using your critical thinking skills. The following examples the first-an eloquent metaphor and the second-a logic problem help bring this message across to all of us. 

Learning to Listen

The man whispered, "God, speak to me." And a meadowlark sang. But the man did not hear.

So the man yelled "God, speak to me." And, the thunder rolled across the sky. But, the man did not listen. The man looked around and said, "God let me see you." And a star shined brightly. But the man did not notice.

And, the man shouted, "God show me a miracle." And, a life was born. But, the man did not know.

So, the man cried out in despair, "Touch me God, and let me know you are here." Whereupon, God reached down and touched  the man. But, the man brushed the butterfly away and walked on.

How simply God does speak to us every day....

Makes Sense?

Four guys are driving cross-country together 

  • one from Idaho, 
  • one from Iowa, 
  • one from Florida, 
  • and the last one is from New York.

A bit down the road the man from Idaho starts to pulling potatoes from his bag and throws them out the window.

The man from Iowa turns to him and asks, "What are you doing?" The man from Idaho says, "Man, we have so many of these things in Idaho they're laying around on the ground-I'm sick of looking at them!"

A few miles down the road, the man from Iowa begins pulling husks of corn from his bag and throwing them out the window.

The man from Florida asks "What are you doing that for?" The man from Iowa replies, "Man, we have so many of these things in Iowa I'm sick of looking at them!"

 Inspired by the others, the man from Florida opens the car door..... and pushes the New Yorker out.

The Eyes Have It

Don't cheat! Try to figure it out before you scroll down after the last question. 

  • You're driving a bus that is leaving from Pennsylvania and ending in New York. 
  • To start off with, there were 32 passengers on the bus.
  • At the next bus stop,11 people get off and 9 people get on. 
  • At the next bus stop, 2 people got off and 2 people got on. 
  • At the next bus stop, 12 people got on and 16 people got off. 
  • At the next bus stop, 5 people got on and 3 people got off.
  • What color are the bus driver's eyes? 
  •  
  •  
  •  
  •  
  •  
  •  
  •  

The key to understanding the problem is focusing on the right information. If we assume it is critical to keep track of the number of people getting on and off the bus, we focus on information that turns out to be unessential. It distracts us from the important information. The answer to the problem is found in the first sentence. YOU are driving the bus so the color is of course the color of YOUR eyes. 

Two Nuns

Two nuns went out of the convent to sell cookies. One of them is known as: Sister Mathematical (SM) and the other one is known as Sister Logical (SL). It is getting dark and they are still far away from the
convent.

SL: Have you noticed that a man has been following us for the past half-hour?

SM: Yes, I wonder what he wants.

SL: It's logical.  He wants to rape us.

SM: Oh, no!  At this rate he will reach us in 15 minutes at the most. What can we do?

SL: The only logical thing to do of course is that we have to start walking faster.

SM: It is not working.

SL: Of course it is not working.  The man did the only obvious thing to do. 

...........He started to walk faster too.

SM: So, what shall we do?  At this rate he will reach us in one minute.

SL: The only logical thing we can do is split. You go that way and I'll go this way.  He cannot follow both of us.

............So the man decided to go after Sister Logical.

Sister Mathematical arrives at the convent and is worried because Sister Logical has not yet arrived.

Finally, Sister Logical arrives.

SM: Sister Logical!  Thank God you are here!  Tell us what happened!

SL: The only logical thing happened.  The man could not follow both of us, so he followed me.

SM: So, what happened?  Please tell us.

SL: The only logical thing to happen.  I started to run as fast as I could.

SM: So what happened?

SL: The only logical thing to happen.  The man also started to run as fast as he could.

SM: And what else?

SL: The only logical thing to happen.  He reached me.

SM: Oh, no!  What did you do then?

SL: The only logical thing to do.  I lifted my dress up.

SM: Oh, Sister. What did the man do?

SL: The only logical thing to do.  He pulled down his pants.

SM: Oh, no!  What happened then?

SL: Isn't it logical, Sister?  .............

A nun with her dress up can run faster than a man with his pants down.

(And you thought it would be dirty!  Say two Hail Mary's... : )

Chocolate Math

Have you ever mixed chocolate and math? Here is a simple logic problem to give you that experience...

1. First of all, pick the number of times a week that you would like to have chocolate. (try for more than 1 time but less than 10 times)

2. Multiply this number by 2.

3. Add 5.

4. Multiply it by 50...we'll wait while you get the calculator.........

5. If you have already had your birthday this year add 1751....If you haven't, add 1750 ..........

6. Now subtract the four digit year that you were born. 

You should have a three digit number .....

The first digit of this number was your original number (i.e., how many times you want to have chocolate each week).

The next two numbers are your age.

The year 2001 is the only year in which this will work so be sure to spread it around before it loses its taste, we mean value.

Be Sure Your Arguments are Valid as well as Reality Based!

In your solving problems, resolving conflicts, and decision making be sure that your arguments which you are using to support your positions on the matter are logical, valid and based in reality. To do this be sure that you are using structures for your arguments which are valid. Arguments can have two valid and two invalid structures:

 
Structure of Argument Antecedent Consequent
valid Affirming (modus poens) Denying  (modus tellens)
invalid Denying Affirming

Remember, however that you could have a valid structure for your argument but that it does not necessarily follow that your conclusions are like wise based in reality. 

For example: 

Antecedent: You must have the proper materials with you to accomplish a task.

Consequent: The task could be accomplished if you have the proper materials

Valid structure, but not necessarily defensible conclusions: You have the proper materials therefore you could have accomplished the task. or You have the proper materials so you must have accomplished the task. 

Confused? Let's see if this example off the emails helps you understand this issue better:

A Fish Story

A couple went on vacation to a fishing resort up north. The husband  liked to fish at the crack of dawn. The wife liked to read.

One morning the husband returned after several hours of fishing and decided to take a short nap. Although she wasn't familiar with the lake, the wife decided to take the boat. She rowed out a short distance, anchored, and returned to reading her book.

Along came the sheriff in his boat. He pulled up alongside her and said, "Good morning, Ma'am. What are you doing?"

"Reading my book," she replied...as she thought to herself, "duh -- isn't it obvious?"

"You're in a restricted fishing area," he informed her.

"But officer, I'm not fishing. Can't you see that?"

"Yes, but you have all the equipment. I'll have to take you in and write you up."

"If you do that, I'll have to charge you with rape," snapped the irate woman.

"But, I haven't even touched you," groused the sheriff. "Yes, that's true, she replied, "but you do have all the equipment."
