From the words of Tony Cragg himself...

"When you’re born, you’re born with a fantastic organ in your head.  There’s not much in it. And you open your eyes and you start to hear and you feel temperature and smell things and hear things and want to touch things — through your senses. Your senses, you have to see as being your inside body communicating with the outside. So it is collecting all this data about the world. Where you’ve got data you’ve got a syntax. So this, if you like, is some kind of language. Your finding out what surfaces are, what softness is, what hardness is, what noises – everything. So through your senses, you filled up these fantastic senses of perceptions of the world, and you use them very shortly after that to survive. You know what tastes good; you know what noises you don’t like; you know what forms are interesting for you, and whatever. And this is a language. You can’t write it down, but that material is already talking to us. Material gives us a message, and we go out and we read into the material something."
