A very good thread, something I touched on the other day. Without risking sounding like the man (I forget who it was, but no doubt someone will come up with the answer) who said everything that can be invented has been invented in the 19th century, there may well be a finite limit to knowledge as well. Sounds mad? Read on.
There is actually a whole a school of thought that says, pretty much, there are limits of our knowledge, and however special we think we might be, we are in fact an advanced ape with limited senses that got a little further than we probably should have.
There’s a few good books on this subject, one of which is called ‘Impossibility – The Limits of science and the science of limits’, by John D Barrow. I’ll draw on some extracts from the book as this is a complex subject and this book is great at explaining it:
‘The idea of the impossible rings alarm bells in the minds of many. To some, any suggestion that there might be limits to the scope of human understanding of the Universe or to scientific progress is a dangerous meme that undermines confidence in the scientific enterprise. Equally uncritical, are those who enthusiastically embrace any suggestion that science might be limited because they suspect the motives and fear the unbridled investigation of the unknown’.
‘Our study of the limits of science and the science of limits will take us from the consideration of practical limits of cost, computability, and complexity to the restrictions imposed on what we can know by our location in the middle of the Nature’s spectra of size, age, and complexity…But practicalities are not the only limits we face. There may be limits imposed by the nature of our humanity. The human brain was not evolved with science in mind. Scientific investigation, like our artistic senses, are by-products of a mixed bag of attributes that survived preferentially because they were better adapted to survive in the environments they faced in the far and distant past.’
This is a complex, mind blowing book in some ways and not for the faint hearted: It includes cosmological limits, mathematic limits, patterns in reality, paradoxes, time travel, the problem of free will, limits in economics, democracy, technological limits, the forces of nature, the end of diversity, art, culture, the psychology of limits, intractability, consciousness and negativism and draws on the knowledge of many scientists and thinkers.
Here’s an account by English Scientist George Gore, which makes interesting reading:
‘Although we know but little of the actual limits of possible knowledge, there are signs that nature is not in every respect infinite. It is highly probable that the number of forms of energy and of elementary substances is limited…Not only does it appear highly improbable that an unlimited variety of collocations of different atoms, united to form different substances, can exist; but many combinations and arrangements of forces are incompatible, and cannot co-exist. From the considerations, therefore, there is a probably a limit to..the amount of possible knowledge respecting them. The number of laws also which govern a finite number of substances or forces must themselves be finite’.
Of course all this doesn’t sit too comfortably with many of us, who have come to expect ‘progress of science of technology’. Indeed Governments look to scientists to improve the quality of life. We have expectations born from hopes of dreams and ideas that have been incorporated into science fiction. We discard the old and assume the new is the next step and the old is ‘past’. For many, the ideas of science fiction writers have become not just sheer fantasy but expectation.
One day we may figure out to control nature, travel to the ends of the universe and find the answers to everything – including inventing machines more intelligent than us. Or so the story goes. But the actual realisation that when all is said and done, we may not really be all that bright or indeed special is not only frightening but intensely despairing. We might figure these things out, but then again, we might not. We’ve come to expect techno fixes, but as we know there are limits of coal, oil, gas and so on. It may just be that there are finite limits to our ability to figure things out too.
