Solve these moral dilemmas

I answer questions on Quora. One of the items I frequently see there is from theists who ask how an atheist can be moral without believing in 'God'. Of course this is hotly defended by atheists who say, "I don't need a god to tell me what is right and wrong - if you do then there's something wrong with you."

The role of religion in morality has been discussed for many years. Richard Dawkins wrote about it in his book 'The God Delusion' and mentioned a study done by a Harvard professor of biology who investigated to see if atheists and theists had the same morality.

He proposed three scenarios and asked those involved in the study to make yes or no decisions in each case. There was no 'maybe' alternative. Non answers were deemed to be 'no' responses. The results failed to detect any difference between theists and atheists. This was taken to mean that morality is something we do by instinct and evolved with us long before there were religions.

Unfortunately, since Richard Dawkins wrote his book the Harvard professor involved in the research was discovered to be falsifying data and resigned his position in Harvard. That doesn't make the scenarios less valid but we need to repeat them to see if the results are the same. So here's the scenarios. You must choose yes or no to each one and any non-answer will be taken to mean 'no'.

Before you start we need to ask if you consider yourself to be religious. Yes/No 

First scenario
A runaway train is heading towards five people on a railway track. They will be killed unless you switch the train onto another line. There's a single man on that line who will be killed if you do switch the train. You don't know any of the six people.
Do you switch the train and save five people but kill one person? Yes/No

Second scenario
You are by a muddy pond which is about waist deep. There's a small child drowning in the pond who you can easily save but in doing so you will ruin your trousers. You don't know the child.
Do you save the child and ruin your trousers? Yes/No

Third scenario
You are a transplant surgeon. In your waiting room you have six people. Five of them are very sick because they need different organs. They will die if a donor can't be found. You haven't been able to find a suitable donor. The sixth person is healthy and also a perfect match for all five patients. His organs can save them all.You don't know any of the six people and the sick people's organs are not compatible with each other..
Do you kill one healthy person to save five people who are sick? Yes/No

I suspect I know what you have chosen and it won't matter if you believe in a god or not. Yes/No answers in the comments please starting with your answer to 'Do you consider yourself to be religious?'  Add any further comments on the next lines. I'll start you off:

My answers:
No, Yes, Yes, No.
I used my instinctive reaction for the last one and thereby sentenced five people to death instead of one. Scenario 1 is similar but I'm not near the individual to be killed.

How to fix Microsoft's new blurred lockscreen 'feature'.

Which background image do you prefer to see? Blurred or sharp?

Microsoft has now added an 'acrylic blur' effect to the background of the sign-in screen of Windows 10 PCs. Their idea is:
 'the translucent texture of this transient surface helps you focus on the sign-in task by moving the actionable controls up in the visual hierarchy while maintaining their accessibility.
In practice it means you sit staring at a blurred mess while you wait for the computer to start up. This makes the start up process seem to take longer and many people find it intensely irritating.

The Fix

However there is a fix. Here's what to do to remove the blur It involves a registry change so you might want to create a system restore point before you carry out the fix.:


  1. Go to https://www.tenforums.com/tutorials/124993-enable-disable-acrylic-blur-effect-sign-screen-windows-10-a.html#option2
  2. Use the download button for #3 'To Disable Acrylic Blur Effect on Sign-in Screen Background'.
  3. Wherever you saved it at, find the file and double click it.
  4. When prompted click 'Run' 'Yes' and 'OK' in turn.

When you restart your computer you should see no sign-in blur. 

...and Microsoft - adding this 'acrylic blur so that the translucent texture helps focus attention' may help those with lightning fast PCs and Internet connection, but to the rest of us it's as irritating an idea as Clippy was.

The Last of the Innocents - Life before computers and Internet

People born in the mid-to-late 1970s are the last generation of humans on the planet to have grown up without the internet. Social scientists call them the Last of the Innocents. In his book The End of Absence , Vancouver writer Michael Harris calls people who grew up prior to the popularization of digital culture 'digital immigrants' - they have lived both with and without the crowded connectivity of online life.
"Soon no person on earth will remember what the world was like before the internet." he says. I sincerely hope he's very wrong about this because I am one of those Innocents - one of the digital immigrants. Unlike Mr Harris I've been using the Internet to keep up with the advancement of the science of senolytics. There's every reason to believe that the first person to live to the age of 1,000 is alive now.

So what was it like before computers and how was I introduced to them? In fact I was not so much an immigrant but more like the immigration officer.

My first experience was in using the Fortran computer language to program a mainframe computer back in 1969. A dreadful experience. You wrote your program, had it converted to punched tape or cards and then waited three weeks to get a report back on why your program didn't work.
At the same time I experienced mechanical adding machines and first got my hands on an electronic calculating machine. It was as big as an electric typewriter.
By the time I was working as a chemistry teacher in 1973 I had my own pocket calculator - a Sinclair Cambridge Programmable Calculator eventually (sold in the US as the Radio Shack EC-4001)
1980 saw me with a home computer at last, a Sinclair ZX80. It was a tiny machine and had an impressive 1K of RAM to run programs on. Programs were stored on cassette tape and a TV was used as a monitor. It was also my first introduction to a computer manual. I started at the beginning and worked my way through it. I remember learning that I could get it to print a letter on screen using the CHR$ command and a number. I delighted in writing a program to get it to write "HELLO JOHN" on screen one character at a time. It worked!. Then I turned the page and discovered that it could be done in one go by using STRING$.
My next computer was a BBC Model B computer. Each school had been given one and no one at the time knew anything about them. I had expressed an interest while talking to our deputy head teacher in the science break rooom. he told me to take it home and learn about it. I did and spent many hours learning BBC Basic. In no time at all I found myself with six BBC B computers and a class of 30 children teaching them Information Technology. I went on courses but quickly found that I was more advanced than the tutors and ended up teaching IT to other teachers.
After a while cassette tapes were dropped in favour of floppy disk drives. I had great fun with the 5¼ inch floppies which could be placed in a computer eight different ways, only two of which worked (often one way only). They caused constant problems as teachers rang me up or sent a pupil with a note to find out why their disk wouldn't work. Sometimes they would send me a note with the offending floppy disk paper-clipped or even stapled to it! I remember too 8½ inch floppies - anyone else seen one of those? A constant problem was that many floppies were stored in a convenient spot - under the phone. These were old fashioned rotary dial phones with a bell which wiped the floppy disk when the phone rang due to the electromagnet in them.

Networking and hard drives made their appearance… but that's for another blog.
