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?[/i]

> > dhw: I’m glad you’ve now omitted the inverted commas round ‘knew’. So an organism knows it has a problem, communicates with its mates to try and solve the problem, but knowing you have a problem and communicating with others in order to find a solution does not require thought. And elsewhere you have dismissed as “hyperbole” the very idea that communication and problem-solving require thought. “No way,” you said. He who thinks he sees all, sees not his own blinkers (new Taunton proverb).
