In the area of knowledge of natural sciences, facts are needed to establish theories. Sciences rely on the scientific method which involves doing background research – looking at previously known real facts -, constructing a hypothesis based on the facts obtained from the background research and testing it doing an experiment which is based on observation. During the observation process, one realises ‘real facts’, those that do not need to be declared because they are demonstrated through the experiment. Therefore, once a series of facts are compiled, a theory can be established explaining those facts. The theory would not be able to be reliable if it did not have facts that made it a true theory. One decides if a fact is indeed a true fact by using reason which is what allows us to form a logical argument from the observations made. Also, language helps to portray the facts and compile them into a theory since if there were no language, we would not be able to establish theories from any ‘real facts’ since there would not be a way to transmit or communicate them. Theories need to be tested and they must be able to be replicated by following the original process that was done to establish the theory, so in order for it to be explained or replicated, it needs the assistance of language and reason to communicate the theory and evaluate if it is logical, respectively. A real life example is when we tested Newton’s theories of motion in my physics class by doing an experiment with toy cars looking at inertia and impulse, we had access to the facts that made up those theories and hence, we were able to put it into practice and see how they behave.
