Does my excerpt from Daniel Dennett's book peak your interest? Please let me know if you're interested in getting together to discuss the book.
Here is a quote from Daniel Dennett’s book ‘Elbow Room-The Varieties of Free Will Worth Wanting’ :
“As we saw in the previous chapter, it [deliberator] must have the capacity to …..forsee the causal milieu into which it will soon pass. And it [deliberator] must foresee this reliably, swiftly, and accurately. There is a trade-off, however, among these desiderata. If this is to be genuine foresight, and not hindsight, a price must be paid: the device must simplify its information handling tasks. It must throw away or ignore data ……carrying along too much information will frustrate real time prediction. And it cannot jettison just any data; if it is to maintain some modicum of reliability of prediction, it must make the right simplifications.”
I think emotions are part of the evolutionary tool kit that helps us with those simplifications. Yes, we have to watch it so it doesn’t mislead us. BUT…it is still a useful tool.
