WHY CLASSIFY?

Have you ever watched a child playing with Smarties? Very often the child will sort them out into colours.

This might seem an obvious and natural thing to do, but it tells us something very interesting about the

human brain. The child is indulging in an activity which can be described as classification.  Suppose you were

designing a website for a large company or supermarket. One of your tasks would be to sort out the products

into a logical system. More complicated than Smarties, but not really different in essence.
