I'm not convinced that we actually use "rational thought" very much - isn't there a theory that what we think of as "rational thought" is really a narrative constructed after the fact to explain our own deeper thought processes to ourselves in a very post-hoc fashion. I suspect this is why "old fashioned" symbolic AI floundered - it was trying to mechanise how we think we think (or rather how we used to think we think) rather than the actual underlying processes.
