Link to Part 1 of this analogy.
The grappling hook finds firm purchase around a sturdy tree-trunk. I tug at the rope a couple of times to make certain it won’t come loose. Then I start to climb.
At first my footing is secure and I make steady progress up the embankment. About halfway up my footholds start to crumble. A stream of soil dribbles downward. I scurry but the dribble grows into a rushing torrent of matter. The ground disappears beneath my feet but I don’t let go of that rope. My fingers ache. My feet find no purchase. There is strain in my arms, my shoulders, my back. My body rages against my will.
For a time I think of just letting go. The fight is too hard. The potential reward too remote.
“Climb!” she shouts at me, “We need you up here!”
And so I climb.
I’m almost at the top. An arm reaches down over the edge towards me. I grasp the extended hand. Soon I’ll be able to see what it looks like from up there.
