Perhaps when you first dressed up as a ghost and went round the houses asking for sweets you thought to also ask what was the meaning of Halloween and why are we doing this? In case, like me, you didn't, I can share for you that Halloween is a smush together — or portmanteau — of hallow, of old English origin meaning Saint, and e'en, a contraction of the Scots word even meaning eve. So it's really the night before All Hallows or All Saints' day on the 1st of November when Christians celebrated the lives of past Saints and martyrs. It's also part of the season of events called Allhallowtide including All Souls' day on the 2nd of November and sometimes days beyond.

The other Halloween traditions come from a mix of sources over hundreds of years that are both complex and somewhat disputed. I did like that the Jack O'lantern, before transferring itself to a pumpkin in the US, was originally carved out of turnips. And I also read that a mighty one quarter of candy sold in the US is sold for Halloween.

Some of the better, sources, explaining the origins of Halloween.

Halloween

Change of large complex things like people, countries, religions or cultures tends to happen slowly. And because the change is small we might think they’re not changing at all. Our instinct may be that they can’t in fact change because of their innate characteristics. But the destiny instinct misleads us.

Small change adds up to big changes over enough time. And while things may not seem to change in a week or a month or a year, when you look back over decades huge change can happen. Changes in poverty, live expectancy, economies, women’s rights, or attitudes to homosexuality — things that may have seemed at one time that they were hardly changing at all —  have all transformed when we look back over sufficient time. Change that may not have seemed like it was adding up to much is still change.

And, at a time of the year perfect for reflection, here are 4 ways to control our destiny instinct from Gapminder:

Keep track of gradual improvements. A small change every year can translate to a huge change over decades.

Update your knowledge. Some knowledge goes out of date quickly. Technology, countries, societies, cultures, and religions are constantly changing.

Talk to Grandpa. If you want to be reminded of how values have changed, think about your grandparents’ values and how they differ from yours.

Collect examples of cultural change. Challenge the idea that today’s culture must also have been yesterday’s, and will also be tomorrow’s.
