In my wonderful question I am not asking if tree have CNS.
Remi, since you live in Montreal, you should be able to get a copy of
last Saturday's Globe and Mail (Sept 28). In it you will find an article
in which the "thoughts" of trees are discussed. It talks of trees as
clever warriors, thinking on time scales of decades rather than minutes.
They fight wars against changes in their environment, against bugs, and
against all sorts of what we would call "disturbances." What they do is
oppose the disturbance. And that seems like "control."
The article isn't PCT, but it's fun. Furthermore, if you have learned to
imagine what one might say from a PCT view when you read a "conventional"
statement about people, you might be able also to imagine a PCT view of
what the article says about trees.
There are a lot of living cell in my leg who control for oxygen level.
And there are a lot of muscle fibres that control for tension, and joints
that control for angle (except that, of course, these are the _external_
--CEV--correlates of what is actually controlled, the neural signal,
presumably).
In the tree, what is controlled? Do the Test. Does the tree control for
canopy shape? Cut out a few branches, and see whether the canopy regains
its old shape without them. Let's say it does. Then we ask whether the
tree can detect canopy shape. We can't see any sensors for that, so it
is hard to say for sure that the tree is controlling for canopy shape
(we can't say it doesn't, because it might have sensors that we haven't
discovered). Perhaps it is controlling for something else that correlates
with canopy shape. Say, nutrient flow from leaves, which doesn't happen
when the leaves are shaded. Try to find a way of affecting nutrient flow
from some leaves or branches, and see whether canopy shape changes when
the tree does whatever it does to counter the disturbance. And so forth.
You can apply The Test to a tree in the same way you can do it for a person,
but you have to wait longer for your answers.
