You concentrate on the automatic processes involved in the act of communication, as if they precluded any autonomous thought behind the need for it. The bacteria had a problem. They communicated with each other in order to find a solution to their problem. I suggest that if they didn’t know they had a problem, they would not have communicated with each other.[/i]

> > DAVID: [i]They 'knew' they had a problem because, like us, they recognize hunger as an automatic stimulus. Do you think about your automatic responses, or is breathing thoughtful?[/i]

> > dhw: Of course not. You are merely repeating what I said as if it proved your point! When I talk to you, I do not think about vibrating my vocal chords or opening and shutting my mouth or moving my tongue – these are automatic, like the bacteria signals. But I use these automatic movements to convey a message, and the message is the product of my thought. I have a problem, and I tell you about it. The bacteria have a problem and they tell each other about it. How do they know what to signal if they don’t know what they’re signalling about?
