“When a carpenter wants to cut a half-dozen boards to the same length, he is unlikely to measure each one, mark it, and then carefully guide his saw along the line he has made on each board. Rather, he will make a jig
A jig reduces the degrees of freedom that are afforded by the environment. It stabilizes a process, and in doing so lightens the burden of care—on both memory and fine muscular control. The concept of a jig can be extended beyond its original context of manual fabrication. As David Kirsh points out in his classic and indispensable article “The Intelligent Use of Space,” jigging is something that expert practitioners do generally, if we allow that it is possible to jig one’s environment “informationally.”

The structure of modern humans must be the result of the change in the terms of natural selection that came with the tool-using way of life. From the short-term point of view, human structure makes human behavior possible. From the evolutionary point of view, behavior and structure form an interacting complex, with each change in one affecting the other. Humans began when populations of primates, about a million years ago, started the bipedal, tool-using way of life.

“Man the toolmaker is also in a sense man the spiritual adventurer, when willingly and deliberately, and with a sense of origination, he allows the tools to take him off in their own directions, mindful at the same time that they must not be allowed to dominate him”
- James Fiebleman "Philosophy of Tools"
“Tools link man with his background; they constitute that extension by means of which he seeks to intrude himself into that part of nature which he has not yet altered.”
-James Fiebleman "Philosophy of Tools"
“ Every kind of capitalist production… has this in common, that it is not the workman that employs the instruments of labor, but the instrument of labor that employs the workman.”
- Karl Marx
