Philosophy & Ethics

You can be a doctor without becoming an American citizen, people move here all of the time and go to medical school.

They just do it legally. The US president has used an executive order to grant amnesty to an unknown number of illegal aliens currently residing in America and now a group of scholars writing in Academic Medicine contend that not only should people in the US be able to go to medical school if they apply, it is an ethical mandate.

It is an unfortunate paradox: if you’re bad at something, you probably also lack the skills to assess your own performance. And if you don’t know much about a topic, you’re unlikely to be aware of the scope of your own ignorance.

Knockaloe Camp. Stefan Manz

The German-Jewish painter and writer Paul Cohen-Portheim had spent a peaceful summer in 1914 visiting friends in Devon and enjoying the beautiful south-west coast.

But his idyllic holiday came to an abrupt end after Britain’s entry into war on August 4. Despite there being no suggestion of any sympathy towards his homeland’s military ambitions, Cohen-Portheim was classified as an “enemy alien” and prevented from leaving the country.

This is a commonly used argument, indeed often taken for granted. We can simulate physics on a computer. So, the argument goes, what is to stop us eventually simulating your whole body including your brain? And if so, is it not just a matter of time, and increasing computer power before we have exact simulations of humans as computer programs? Programs whose behaviour is indistinguishable from humans?

This is a staple of many science fiction stories of course. But some logicians, philosophers and physicists think there are flaws in this argument.

We know the laws of physics are incomplete. Could there be physical processes which for some reason are impossible to simulate using a computer program? And could processes like that go on in a human being?

How much risk can health workers be asked to take on? Mike Segar/Reuters

Taking care of sick people has always involved personal risk.

From plague to tuberculosis to smallpox to SARS, health-care workers have put themselves in danger in the course of fulfilling their duties to care for others. Many have lost their lives doing just that.

In 2005, John Ioannidis wrote a paper in PLOS Medicine showing that most published research findings are false.

Disputes about the existence of God — like most disputes about religion, politics, and sex — almost always generate heat but not light.

The question of the existence of God seems intractable. As with other philosophical questions, there is no method to follow in seeking to answer it. Moreover, there is no prospect of reaching an agreed answer to it.

Academic freedom has been put in the spotlight with two universities recently coming down hard on academics for comments on social media.
