Noam Chomsky

« All quotes from this author
 

Science talks about very simple things, and asks hard questions about them. As soon as things become too complex, science can't deal with them... But it's a complicated matter: Science studies what's at the edge of understanding, and what's at the edge of understanding is usually fairly simple. And it rarely reaches human affairs. Human affairs are way too complicated. In fact even understanding insects is an extremely complicated problem in the sciences. So the actual sciences tell us virtually nothing about human affairs.

If the alternative that's being offered to what physicists now talk about - a big bang, a spontaneous singularity which gave rise to the origin of the universe - if the alternative to that is a divine intelligence, a creator, which would have to have been complicated, statistically improbable, the very kind of thing which scientific theories such as Darwin's exists to explain, then immediately we see that however difficult and apparently inadequate the theory of the physicists is, the theory of the theologians - that the first course was a complicated intelligence - is even more difficult to accept. They’re both difficult but the theory of the cosmic intelligence is even worse. What Darwinism does is to raise our consciousness to the power of science to explain the existence of complex things and intelligences, and creative intelligences are above all complex things, they’re statistically improbable. Darwinism raises our consciousness to the power of science to explain how such entities - and the human brain is one - can come into existence from simple beginnings. However difficult those simple beginnings may be to accept, they are a whole lot easier to accept than complicated beginnings. Complicated things come into the universe late, as a consequence of slow, gradual, incremental steps. God, if he exists, would have to be a very, very, very complicated thing indeed. So to postulate a God as the beginning of the universe, as the answer to the riddle of the first cause, is to shoot yourself in the conceptual foot because you are immediately postulating something far far more complicated than that which you are trying to explain. Now, physicists cope with this problem in various ways, which may seem somewhat unconvincing. For example, they suggest that our universe is but one bubble in foam of universes, the multiverse, and each bubble in the foam has a different set of laws and constants. And by the anthropic principle we have to be - since we’re here talking about it - in the kind of bubble, with the kind of laws and constants, which are capable of giving rise to the evolutionary process and therefore to creatures like us. That is one current physicists’ explanation for how we exist in the kind of universe that we do. It doesn’t sound so shatteringly convincing as say Darwin’s own theory, which is self-evidently very convincing. Nevertheless, however unconvincing that may sound, it is many, many, many orders of magnitude more convincing than any theory that says complex intelligence was there right from the outset. If you have problems seeing how matter could just come into existence - try thinking about how complex intelligent matter, or complex intelligent entities of any kind, could suddenly spring into existence, it’s many many orders of magnitude harder to understand.

The true line is not between “hard” natural science and “soft” social sciences, but between precise science limited to highly abstract and simple phenomena in the laboratory and inexact science and technology dealing with complex problems in the real world.

 
Herbert Simon
 

But what I really believe is that both he and Mr Wong are innocently guilty of the twentieth century fallacy that technology can be applied to the conduct of human affairs. They cannot believe that anything can work efficiently unless it has been programmed by a computer and have lost faith in the forces of the market and the human actions and reactions that make it up. But no computer has yet been devised which will produce accurate results from a diet of opinion and emotion. We suffer a great deal today from the bogus certainties and precisions of the pseudo-sciences which include all the social sciences including economics. An article I recently read referred to the academic’s “infernal economic arithmetic which ignores human responses”. Technology is admirable on the factory floor but largely irrelevant to human affairs.

What I have discovered in 20 years of studying the universe, from here to there to everywhere, is that the universe is complicated, and when things happen, it is almost never like ‘A happened and therefore B’. No, A happened and therefore B, C, D and E, but then there is this thing F, and that had a 10% effect, and that prompted G to go back and tip over A, and it is always like this – everything is interconnected. And so a lot of these far-right fundamentalist religion people, and a lot of these people who are anti-global warming, anti-evolution, anti-science, what they do is they take advantage of the fact that things are complicated, and their lives are based on things being simple – if we do this, then this will happen – if we invade Iraq, we will be treated as liberators, if we pray, then good things will happen, and this stuff is wrong. But we have a culture where people are brought up to believe in simplicity, and if A then B. And so when you point out that scientists say the earth is warming, but we had a really devastating winter this year, then these people will say “oh, obviously global warming is wrong”. No, global warming can cause worse winters locally. It’s complicated. But people don’t want to hear “it’s complicated”, and boy, the conspiracy theorists and anti-scientists take full advantage of that.

 
Phil Plait
 

Everything that has been said, and every conclusion that has been tentatively put forward, is quite frankly speculative and uncertain. We have tried to discuss whether present-day science has anything to say on certain difficult questions, which are perhaps set for ever beyond the reach of human understanding. We cannot claim to have discerned more than a very faint glimmer of light at the best; perhaps it was wholly illusory, for certainly we had to strain our eyes very hard to see anything at all. So that our main contention can hardly be that the science of to-day has a pronouncement to make, perhaps it ought rather to be that science should leave off making pronouncements: the river of knowledge has too often turned back on itself.
