Because new waves of migrants continue to make healthy, happy new futures in Australia while the Aboriginal people seem to suffer continued low employment and poor health.

I’m fascinated by moral integrity, greed and art. I also have mixed feelings about didacticism, especially in art. My question stems from a recent ethics forum centred on Art and Ethics where an esteemed ethicist provoked the audience with the statement that the only ethical art was one that instructed or commented on Climate Change (and/or social inequality).

Should we be eating them?

I’m interested in what is time and how it is linked to space. I wonder if it will be possible to time travel.

Everyone has an opinion on this, and many other sex-related topics. I’d like to know the answer.

I’d love 10 hours, 100 minutes and 100 seconds in a day – scientists would love it. But could people cope with such a fundamental change to everyone’s (in the world!) lives?

The need for humanity and human empathy underpins so much of what is going wrong in the world right now. Now perceived as a weakness to be overcome if right thinking is to be achieved. Others should care because we all wish for kindness and fairness in our lives.

Like many others, my husband and I are increasingly convinced that living like this is the best thing we can do for the planet. However, I recently read an article that spoke of the many who believe the opposite. They argue that developing increasingly sophisticated technologies, such as higher levels of artificial intelligence, is the best solution to most, if not all, of our problems – and they have the money and power to make these technologies reality. The article also posited the question, ‘Would I want a future foisted upon me by [Silicon Valley venture capitalist Marc] Andreessen and his fellow founders?’ This prospect frightens me – as it would many others. Can we resist this vision of the future?

Although I was raised as a strict Irish-style Roman Catholic, after many years of deep thought, I am now an atheist, humanist, rationalist and sceptic, and have come to the conclusion that this is the most important unanswered philosophical question. I do not believe there is any need to postulate a creator, because belief in a creator god leads to the obvious next questions of who or what made god, and who or what made who or what made god, and so on indefinitely.
