An example of an extended metaphor used by a scientist:

"The law of causality is neither true nor false. It is rather a heuristic principle, a signpost – and in my opinion, our most valuable signpost – to help us find our bearings in a bewildering maze of occurrences, and to show us the direction in which scientific research must advance in order to achieve fertile results."
