Dear Anatoly -- I would say that both are important to lifelong learning - that is, new experience (sensory/motor data), and the practice of old experience (sensory/motor data) are both important. Obviously new data is important to the discovery of new areas of our environment and becoming proficient in new actions. However, relearning old things is equally important. There is a simple reason for this, a reason that we forget because it happens everyday for us, and it is -- old data that has been consolidated (integrated) within our long-term memories will gradually fade if not reinforced through practice. Much of this relearning comes to us daily - dialing a friends phone number, writing an address, hearing a person speak and saying their name, walking to a door and turning the knob, driving our car, tying a password (this is not just recalling data, it is also moving or hands, fingers, our mouths, or legs and sensing that movement as data).
As I watched my mother get older, I saw a decrease in her ability to converse efficiently and effectively, not just because of hearing loss, but also because of cognitive loss, due to hearing loss. She was not "using it" therefore she was "losing it". This is well understood in senior care and thus we are all encouraged to be as active as possible in our lives at all ages.
I hope that this perspective is helpful .. Cheers from Nova Scotia .. Danny
This question points out to the very core of logics. In logic, we can differentiate between monotonic and non-monotonic logics. The dormer are those in which new information cannot inviolate previously acquired information. On the contrary, the latter are those in which new information can invalidate previous information.
In other words, this leads us to very sensible issues such as fundamentalism, liberalism, an the like.
Very interesting Carlos .. The problem of consolidation is most certainly connected to non-monotonicity in logic. I agree. I would indicate a subtlety . Sometimes new information (data) extends/clarifies knowledge in terms of range or resolution. We come to realize that an inference (deductive or inductive) dependents on factors that were previously not appreciated.
Indeed, dear Daniel. Such a clearance and/or clarification (I know the difference) is a modification of previously acquired information. Monotonic logic is a fancy and elegant expression for referring to fundamentalism - whether political, religious or philosophical, f.i. In other words, it consists in the "myth of the origin" - by which we create and re-create the myth.
