The Protagoras Paradox.

Read an interesting one while surfing the net. Note its relationship with the dilemma in handling the Corona virus issue.

Over 2000 years ago, in Greece, there was a lawyer named Protagoras. A young student, Euthalos, requested to apprentice under him but was unable to pay the fees. The student struck a deal saying, "I will pay your fee the day I win my first case in the court".

Teacher agreed. When the training was complete and a few years had elapsed without the student paying up, the teacher decided to sue the student in a court of law.

The teacher thought to himself  : "If I win the case, as per the law, the student will have to pay me, as the case is about non-payment of dues. And if I lose the case, the student will have to pay me because he would have won his first case. Either way I will get paid". The student's view was, "If I win the case, I won't have to pay the teacher as the case is about my non-payment of fees. And if I lose the case, I don't have to pay him since I wouldn't have won my first case yet. Either way I will not pay the teacher".

This is known as the Protagoras Paradox, which ever way you look both have equally convincing arguments, one can go either way in supporting the teacher or the student and would not be wrong.

Those of us in medical practice often come across such situations, either in making a diagnostic or therapeutic decision. One physician can recommend a course of treatment based on scientific evidence and another can recommend a diametrically opposite course again based on medical evidence. Right or wrong, but some merit would exist on both sides. Often the physician himself is having an internal struggle to make a decision about the most appropriate course of action, Protagoras and Euthalos are arguing in his mind, to do this or to do that. The horns of dilemma are tearing him apart.

But what triggered this essay was a tweet by Donald Trump, "Hope the cure is not worse than the disease". I hate to say, but I find some merit in this tweet. In our global attempt to flatten the COVID curve, I hope we do not flatten the economic curve. The question is what's the best way forward. One group recommends 'total lock down' to break the transmission chain, based on evidence from China, they managed to control the spread of the virus by ruthless lock down and three months later they are showing that the disease is controlled in Wuhan. On the other hand, the other school of thought is graded isolation and protection of the elderly and very young and those with co-morbidities, let it spread among the young and the healthy, after all the disease ultimately  will be controlled when we achieve 'herd immunity'.

The medical community is divided in these two groups. To enforce complete lock down or graded isolation?

To complicate the issue the epidemiologists have joined the bandwagon with a cacophony of statistical analysis. From Rosy to Doomsday predictions. If we don't do a complete lockdown then a million people will die in 1 year. No say some, more like 90 million will die in 1 year. Whose data analysis is correct? Some suggest do nothing, nature will take over in a few months and all will be well, they quote historical data to justify their recommendations. On whose inputs should we base our disaster management strategy?

Then come the economists with their doomsday predictions. If this continues till May our medical resources will be overwhelmed, agriculture will suffer, food shortages will occur, production will come to a standstill. There will be an economic crisis of the proportions that the world has not seen ever. So, break this lock down nonsense and let's get back to work as usual.

What will our political masters do? My guess is they will listen to medical experts, epidemiologists and economists. Then they will decide what course of action will ensure their survival, what will get them people's votes and they will run with that. At present "Lock down" finds favour with them. Boris Johnson in UK had to abandon the recommendations of the medical community  about graded response because the people's perception became that our Government is not doing enough to protect us, citizens. That means revolt against him. So, screw it, lets go with total lock down if that's what the people want.

Gradually people will get tired of lock down and demand - let life go on. Then with equally convincing  arguments the governments will say the time has now come to lift the blockade, we have controlled the contagion, we have won.

Incidentally, the Protagoras Paradox has not been resolved till date.

Students in Law school still hold mock trial and give arguments on both sides.......without any resolution of the dispute.   


Tailpiece.

The 1st of April. A classmate of mine was the first caller of the day and we did have a long chat. Got up at 6, the chores and was ready well in time. Suma had made tasty, 'achadas' for breakfast.

Went to the nearby bakery to buy milk and rusks. The shopkeeper was very keen to talk and I spent some time there.
