On tools

To be a human without tools is to be a cat without claws, a rabbit without ears, or a hawk without wings.

We have natural properties that allow us to compete in nature. Our minds allow us to create simple or complex tools that give us the edge against creatures that have more obvious tools. Since we can't "think" our enemies to death we think of ways to accomplish our goals and to maintin our edge in nature. One may agrue that we don't need our tools in modern society, but to be without our natural edge is naturally suicide.
