How Certain Can We Be About Science?

Extracts from this document...


How Certain Can We Be About Science? For centuries humankind has questioned the universe around it. This has given rise to a new faith, a faith known as Scientism, the unquestioning belief that science is correct in every matter and cannot be disproved. Yet, there are many things which cannot be explained by science and which science cannot deal with. The main aim of a scientist is to come up with some principle or theory which can explain the behaviour of a section of the universe, such as the behaviour of a gas when it is heated. To do this a scientist must first formulate a hypothesis from observation of the universe, then prove it to be true by carrying out experimentation in a controlled environment to create a theory. ...read more.


Thus science is limited only to the parts of the world that exist to the eye, it cannot question that which only exists in the mind, the soul or outside this universe. Science cannot even prove that the universe exists. The philosopher Rene Descartes questioned the existence of the universe and wither or not what we know as the world is real. He concluded that if you are experiencing something, then you must exist in order to experience it, or as he put it "Cogito ergo sum" or "I think therefore I am". There is no way for a scientist, using the scientific method, to prove that what is known, as the world is not a dream or an illusion. ...read more.


There is also a major flaw in the scientific method. The human body gives out heat, reflects light, absorbs Oxygen and creates Carbon Dioxide. The very presence of a person in a room will increase the temperature, alter the air flow patterns in the room and alter the O2 to CO2 ratio. In an experiment these factors can severely alter the results of an experiment. This is known as Heisenberg's Uncertainty Principle and means that no scientific experiment can be carried out with complete accuracy as the act of observing the experiment alters the conditions in which is carried out. Overall, we can never be certain about science. Different people see the same thing in different ways and it is impossible to create the perfect conditions for accurate experimentation, proving that scientism is a flawed belief. ...read more.
