WHAT. IS THIS. THING. CALLED. SCIENCE? ALAN. CHALMERS. Mc. Graw. Hill. Education Science as knowledge derived from the facts of experience. 1. A widely Transforming the experimental base of science: historical examples. Alan F. Chalmers introduces his book What Is This Thing Called Science? with Readers most probably start to question whether science has the ultimate . Since its first publication in , Alan Chalmers's highly regarded and widely read work--translated into eighteen languages--has become a classic introduction.
All knowledge that is real knowledge is derived through the scientific method. Everything else is poetry, imagination. Experiments are how we know that rice is edible and rain is wet and that these other bipeds are sentient creatures like us: these are inferences we have made non-verbally and confirmed through experiments we carried out when we were very young.
They are theories that cannot be conclusively proved and disproved. They are no different in essence from the kinds of inferences and confirmatory experiments that are done by casts of thousands at the Large Hadron Collider. All knowledge is obtained in the same manner.

It is the same thing. A philosophy that capitalises Science and sets it apart from scientia as something distinctive and special is pernicious.
That is my first quarrel with Chalmers. He was also a practicing scientist: he graduated summa cum laude in chemistry from Harvard.
If you want your ideas to be clear, you should read it. No, in Chapter 1 this book jumps from classical empiricists like Locke and Hume to the logical positivists in Vienna as if there was no such continent as North America and no such time as the 19th century. Of course you are free to write a book on the philosophy of science and leave pragmatism out. That is my second quarrel with Chalmers. Well, no.
All the facts are the basis of science.
If you want to reaffirm something you know, if you want to point to something as an example to support scientia, settled science, or whatever you want to call it, there is a vast amount of easily accessible material that is relevant. Only if you want to extend knowledge in some particular direction might there be a need for you to devise a complicated experiment.
What you have done is look at the facts you already know, or think you know, and the theoretical framework you use to structure them, and you have come up with an idea, A.
You have computed the consequences of idea A, and one of them is B. So you are collecting facts to find out whether or not B seems to occur.
This might be very hard. But, you are not tied to that particular experiment; you might be able to think of a better experiment that could test the same hypothesis you have thought of in some different way. Tomorrow someone might invent a technique that makes it dead easy to determine G.
It is very, very, very physics-centric. If I am a sociologist, applying the scientific method, there are a lot of relevant facts I can learn by measuring the hair length of youths in Sydney. I can test the proposition that changes in hair-length are correlated to changes in voting behaviour in that demographic, with a shift to shorter hair possibly foreshadowing a swing to the Liberal party. I can look for annual trends: does hair length peak during the winter, when it is colder, or in the summer, when youths are most likely to take long holidays?
I can couple my measurements with a traditional social-sciences survey instrument and see how well facial hair length correlates with social phenomena such as hipsterism or conservative Islam; can I use it as a proxy to map the spatial and temporal variation in these trends?
I am sure there are enough relevant research questions there to support a whole Sydney Journal of Adolescent Capillometry. Such research questions, which are perfectly scientific, are ignored in this book. Of more concern to me as a hard scientist concerned with public policy is the neglect of the historical sciences.
And these are the sciences where science is most often embroiled in controversy and one side or the other or both want to harness the authority of science to support their view. What allows us to argue confidently that it happened?
What allows us to say anthropogenic global warming is scientific? The challenge of any philosophy of science today lies solidly in this area of the historical sciences.
These are: a Facts are directly given to careful, unprejudiced observers via the senses b Facts are prior to and independent of theory c Facts constitute a firm and reliable foundation for scientific knowledge Reading as a pragmatist, all of these are naive.
And, there is no certain firm and reliable foundation for knowledge: we can hope to asymptote towards knowledge which is of more and more utility, reaching truth if this process is infinitely prolonged, but we can never know for certain that our foundation is firm and reliable. In Chapter 4, Chalmers gets into another muddle in discussing induction.
How is the principle of induction to be validated? There are two possibilities, he says, by logic and by experience. He rejects the appeal to logic, but instead of addressing the appeal to experience he reformulates it as an appeal to logic , making the following self-evidently ridiculous syllogism for us to mock: a The principle of induction worked successfully on occasion x1 b The principle of induction worked successfully on occasion x2 Therefore: The principle of induction always works We are not looking for a proof that the principle of induction always works.

The appeal to evidence is a pragmatic one. How do I go about doing these things? By following laws determined inductively. I can never know, and I will never care, whether these laws are always true. It is the practical success of the laws in producing useful outcomes that I care about.

This explanation sounds like Buddhism where Gautama Buddha rejected the existence of a creator deity, refusing to endorse many views on creatio. In the process, it sheds new light on the nature of science and its origins in the Scientific Revolution.
