"At which point a tree ceases to be a tree? That’s a rather complicated question. Let’s try to figure it out together. Perhaps, it happens as soon as the tree is cut down? Or maybe when it’s turned into planks. It likely happens when they varnish those planks. Or maybe when they make a chair out of those planks? Answering this question with full certainty is near impossible. But we are convinced that our chair is still a tree."
