In a conversation with Joe Truss yesterday, we were talking about bridging metaphors, and how they connect ideas in ways that simple comparisons do not. It occurred to us that the idea itself of a bridging metaphor is a metaphor… the word ‘bridge’ takes the physical idea of a bridge and transforms a relationship into something more tangible to understand.

The world is filled with metaphorical bridges. When we make a transition we often use a bridge metaphor of ‘crossing over’ or taking us from one place to the next. Or we find bridges as meeting points in arguments or negotiations.

Whether we are ‘meeting half way’, ‘not worrying until we have to cross that bridge’, or building bridges between people or ideas, we are using the bridge as a metaphor. We are constructing a way to get us over a challenge.

In many ways the idea of a metaphorical bridge is more powerful than a physical bridge. We yearn for metaphorical bridges. A perfect example of this is the discrepancies between Newtonian Physics and Relativity. We seek the bridge. We want to know why the math for each do not mesh and we want that unifying theory to ‘bridge the gap’. We seek bridges to make sense of the world, of relationships between people (connection and communication) and ideas, not just geography.

The biggest challenge we face in the next few decades is that of bridge building. It seems the terrain is getting tougher to pass rather than easier. Countries at war, religious beliefs fostering hate, political parties not willing to show any sign of cooperation, of ‘meeting part way’.

As a species we seem to spend more time tearing down bridges than building them. We need to change this. We need to be metaphorical bridge builders. We need to construct ways of getting over the challenges we face. We need to support ideas that bring us closer together.

((And in case you missed it, bouts of the last two sentences are bridging metaphors.))
