" Metaphor is one of the mechanisms by which our imaginations assimilate the world. We give sense to things through comparison. We theorise about things we are trying to understand and describe by alluding to characteristics they share with other things. We create new things by emulating the familiar. The attraction of metaphor is not exclusive to our attempts to make sense of the world through words. Thousands of years ago, architectural construction originated in metaphor. Sometime in the distant past, we began consciously constructing places as lasting metaphors for those ephemeral places we make just by being in the world or adopt in our natural surroundings. "
