A brief hiatus
Apologies for not posting anything recently. I have something in the works at BigThink and a few more in the pipeline but it has been hard finding the time to blog recently. I hope to be back to it in a couple of weeks.
The evolution of meaning – from pragmatic couplings to semantic representations.
When living creatures perceive something, they’re concerned with two questions: What is it? and: What should I do about it ? You might think that the machinery for answering those questions evolved in that order – like you’d have to know what something is before you can know what to do about it – but it seems likely to have been the opposite. The actions of the simplest creatures when faced with various stimuli in the world are mostly coordinated by pragmatic couplings – signals that are prescriptive rather than descriptive . But these mechanisms laid the foundation for the evolution of decoupled internal representations with true semantic content. For living organisms to go on persisting – which, let’s face it, is their whole schtick – they have to take in energy and raw materials (food, oxygen) and use them to keep their internal economy humming. Many organisms manage this process – known as homeostasis – by staying put and letting resources come to them. The problem with this
Looking forward to seeing your BigThoughts :)
ReplyDeleteYou don't have to worry about it. I know that it is quite hard to give enough time to blog something. It takes a lot of time that why I am impressed with sites like xlpharmacy facts because they are adding content constantly.
