A POPULAR question in philosophy is this:

if a tree falls in a forest and no-one is around to hear it, does it make a sound?

This is not the forum in which to speculate on matters of observation and knowledge of reality; what we can say with certainty, however, is that if someone plants a tree in honour of a loved one, that is an act of remem­brance that will enrich the lives of many.

One who can bear witness to that truth is West Calder woman Margaret Murison, who yesterday planted a rowan tree at Scotland's First World War Centenary Wood on the Ministry of Defence training estate in the Pentland Hills near Edinburgh. She was honouring her grandfather and great-uncle, who both fell in the Battle of Ypres.

Eventually 50,000 trees will be planted. It is hoped the creation of the memorial woods will allow people to revisit and keep alive their family stories of those who served and lived during the First World War.

For £20, readers can dedicate a tree of their own, with the help of The Herald and Woodland Trust Scotland. It truly is a satisfying and rewarding way to honour and cherish one's roots.
