… Lineal thinking will always generate either the teleological fallacy (that end determines process) or the myth of some supernatural controlling agency.
This is the third of three posts today from Mind and Nature: A Necessary Unity by Gregory Bateson (2002; first published in 1979):
… We use the same words to talk about logical sequences and about sequences of cause and effect.
… But the if . . . then of logic in the syllogism is very different from the if . . . then of cause and effect.
… Thirty years ago we used to ask: Can a computer simulate all the processes of logic? The answer was yes, but the question was surely wrong. We should have asked: Can logic simulate all sequences of cause and effect? And the answer would have been no.
When the sequences of cause and effect become circular (or more complex than circular), then the description or mapping of those sequences onto timeless logic becomes self-contradictory. Paradoxes are generated that pure logic cannot tolerate. An ordinary buzzer circuit sill serve as an example, a single instance of the apparent paradoxes generated in a million cases of homeostasis throughout biology. The buzzer circuit is so rigged that current will pass around the circuit when the armature makes contact with the electrode at A. But the passage of current activates the electromagnet that will draw the armature away, breaking the contact at A. The current will then cease to pass around the circuit, the electromagnet will become inactive, and the armature will return to make contact at A and so repeat the cycle.
If we spell out this cycle onto a causal sequence, we get the following:
If contact is made at A, then the magnet is activated.
If the magnet is activated, then contact at A is broken.
If contact at A is broken, then the magnet is inactivated.
If the magnet is inactivated, then contact is made.This sequence is perfectly satisfactory provided it is clearly understood that the if . . . then junctures are causal. But the bad pun that would move the ifs and thens over into the world of logic will create havoc:
If the contact is made, then the contact is broken.
If P, then not P.The if . . . then of causality contains time, but the if . . . then of logic is timeless. It follows that logic is an incomplete model of causality.
… Lineal thinking will always generate either the teleological fallacy (that end determines process) or the myth of some supernatural controlling agency.
What is the case is that when causal systems become circular, a change in any part of the circle can be regarded as cause for change at a later time in any variable anywhere in the circle. It thus appears that a rise in the temperature of the room can be regarded as the cause of the change in the switch of the thermostat and, alternatively, that the action of the thermostat can be regarded as controlling the temperature of the room.
… we should define “stability” always by reference to the ongoing truth of some descriptive proposition. The statement “The acrobat is on the high wire” continues to be true under impact of small breezes and vibrations of the wire. This “stability” is the result of continual changes in descriptions of the acrobat’s posture and the position of his or her balancing pole.
It follows that when we talk of living entities, statements about “stability” should always be labeled by reference to some descriptive proposition so that the typing of the word, stable, may be clear.
… Similarly, all statements about change require the same sort of precision. Such profound laws as the French “Plus ça change, plus c’est la même chose” owe their wiseacre wisdom to a muddling of logical types. What “changes” and what “stays the same” are both of them descriptive propositions, but of different order.
