I heard part of a radio debate the other day as I was driving around. The topic was whether the pen is mightier than the brush.
I heard Ben Eltham, arts writer for Crikey.com speaking for the brush, and he said something to the effect that we are in the post-literate age. (I'm not sure of the exact wording, but you can listen to the whole debate here.)
Even though he spoke well and made his points clearly, I wasn't convinced that our world is moving away from words.
On the other hand, I've just received a link from a friend to a video in Chinese showing how to separate a yolk from the white of an egg. It's a great technique and I'm going to try it next time I need to perform that task.
I watched the video and understood not one word of the explanation, but the pictures conveyed the meaning in a universal way.
