4: To what extent do we need evidence to support our beliefs in different areas of knowledge?
Many of the areas of knowledge use evidence to support their theories. Evidence helps us to support our theory and maybe convince other people to that. According to English dictionary evidence is one or more reasons for believing that something is or is not true.
Evidence is obviously a very important thing of our everyday life for example your mom requires evidence that you have been in school today or you teacher needs the proof that you have done your homework. Evidence plays also very important role in knowledge. We use it to proof or base our theories on. But is it really that ...view middle of the document...
Lest investigate different types of knowledge to find out if the evidence is a significant, partly significant or not needed at all. As I said before in mathematics you have to come up with convincing demonstration of solution to some mathematical problem, and this fact actually misses the point of evidence which should be something already existing that you can support you theory or belief.
Natural sciences seem to be those ones that need most of evidence to proof something. We can se this in quote said by Lord Kelvin: ‘When you cannot measure, your knowledge is meagre and unsatisfactory.’ This very simple quote indicates that science is a matter of applying theory into the world and proving it by experiments – creating evidence. This work divides evidence into different subcategories. So what categories can we apply in science? This task is not the easy one, because under term science there is hidden many subjects like physics, biology or chemistry. And even those can be divided into smaller subjects or can be combined what creates a small controlled chaos. Nevertheless we can easily say that science requires scientific evidence, which is obtained in a very unbiased way by many people. But science is mostly based on intuition that is later proven by scientific evidence. There is an example that seems to prove the intuition theory:
The theory of gravity by Sir Isaac Newton, who found out the idea when the apple fell down form a tree besides him. At first it was not a scientific experiment but simple event and Sir Newton by intuition believed in it and was able to see something interesting in it. Of course it was not that simple to create the law. This process required many observations and calculations but finally Sir Newton came up with the equation that was proven many times since then. In many cases the scientific facts or theories have very difficult times to be accepted even though that all gathered evidence is proving the theory. In this situation was heliocentric theory of universe established by Copernicus.
The human sciences:
This is the type of knowledge that investigates the humans’ life and their activities. It involves in its study history, sociology, anthropology, and economics, however it does not limit itself only to those categories. Wikipedia says that human sciences uses rational, systematic, and verifiable methodology to gather the data. This also helps it to keep the information valid. This type of knowledge uses a lot of evidence to prove its theories. For example if some company wants to introduce some new product, first they have to analyze customers need, therefore they hire psychologists to create a set of questions for potential customers. Afterwards those psychologists analyze obtained data and then they advise the company about what customers expect from or think about upcoming product. This is a very simple example. Another example can be observing the social changes throughout...
