Why do we need so many tools?

The repeated theme is that each tool is for a specific task. Let us think about the plumber’s wrench. We would not want to try to use that wrench to hammer in nails. So the tool is specific to the task, yet we could use the wrench to solve one problem on a given day, and sometime later, we try to deploy the same tool on seemingly the same problem, and it no longer works. At that point, we can go to our toolbox if we have many tools and begin to try other approaches. Perhaps this time, the pipe that we are trying to tighten requires an additional wrench or one of a different shape. This point is where randomness and unknown slip into the equation. We only know so much about the world through our senses. A variety of tools allows us to solve a wide array of problems that can contain aspects that we cannot readily comprehend.
