What would it be like if women ruled the world? The proposition has been made both as an ambitious feminist dream and as a misogynistic nightmare. There used to be at least one running joke about the dangers of a menopausal female head of state hitting the nuclear button in a hormonal bad mood.
On the more utopian side, there has been a pretty belief that if women were in charge, we would have a more sharing, caring, consensual and peace-loving political and economic order.
We may soon find out. By the autumn of this year, a significant slice of the Western world may be run by women: Hillary Clinton in the United States, Theresa May - the bookies' favourite to be the next prime minister of the United Kingdom - Angela Merkel still in place in Germany, and not forgetting Nicola Sturgeon as the most visible Caledonian leader since Mary, Queen of Scots.
