    Reality is not “rational ” in the sense that “It is a normative concept of reasoning in the sense that rational people should derive conclusions in a consistent way given the information at disposal. It refers to the conformity of one’s beliefs with one’s reasons to believe, or with one’s actions with one’s reasons for action.”

    http://en.wikipedia.org/wiki/Rationality

    Reality is, in the words of Roger Penrose, “non-computable”. Or, in the language of mathematics, np-complete. In every day terms it means that no conceivable computer given billions of years can resolve the solution.

    The hubris of scientism that since we can send a rocket to the moon then we can predict the weather displays a total ignorance of the difference in complexity between the two problems. This unfortunate byproduct of the enlightenment led to some of the horrors of the 20th century – 100+ million people dead in the name of “scientific socialism”.

    Those who place their faith in “coffee house philosophers” rather than the wisdom of the fathers are lost lambs.

    Roy,

    I agree with all that.

    What Penrose said is essentially a rephrasing of Godel. Chaos Theory follows along similarly.

    As a statement about physics, the original comment is fairly bland and uncontroversial. It seems to me that we (people, in general) keep trying to declare that somehow other subjects are different.
