The control process that allows a subgoal to be achieved is a link.
A link is a component of an environmental feedback loop.
A pen provides a link for controlling a perception of writing thoughts.
The link is a link in a chain.
The lever is a link for moving a rock.
But the common use of the shorthand should not lead one to forget that
the link is not the object, but is a link in the feedback path of a
controlled perception.
The concept of link applies not only to properties of physical objects
we call "tools", but also more abstract constructs. For example, the
stability of someone's liking for a particular food can be a link for
controlling a perception of that person's pleasure as a guest at your
table.
from the viewpoint of the control loop, whether the link is a property
of an object is irrelevant.
The tool builder controls perception of the perceptions for which a
property of the tool should be a potential link.
To go into verbal detail every time one wants to talk about a link
would be very tedious, and is often pointless.
That property may be called a "designed link".
A tool like a Swiss Army knife is designed to have many different
properties that could become links for control of frequently
controlled perceptions.
For the thief, his environmental feedback loop is made up of a chain
or network of links, of which the controlled perception "stealing" is
one.
Influencing another's links need not decrease the other's power.
In one of Kent's examples, a whole community of people combine to
build and maintain a road, giving you the power to use a car as a link
for controlling a perception of your movement between two places on
the road, whereas before the road, you might have had to cut your way
through a jungle.
In his LCS IV chapter, Kent points out how stability of social
structures can also be used as a link.
These are fairly stable roles, and each has a designed set of
properties that can be used a link for control of different
perceptions.
The stability of these roles, independent of the person playing the
role, enhances the power of anyone with the ability to use those links
for controlling perceptions.
More generally in power relationships, the conflict issue is in the
availability of links.
The one with more global power (more ability and strength to control a
lot of perceptual variables) has more ability to acquire links, and if
necessary, to deny them to others.
I hope this sketchy introduction gives you an idea of why and when the
concept of a /link/ is useful.
