Most philosophers think that you cannot know that something is true without believing it is true. If you do not believe that a fish cannot breathe out of water, then you do not know it. Believing is a requirement of knowing. That said, how justified must our beliefs be to constitute knowledge? How valuable is this knowledge in which we believe in? I suppose in our society today, the value of knowledge at most times is dependent on the justifications that we give it.
It would seem reasonable to believe that knowledge with the strongest justification is the most valuable, but why? Justification is seen to add value to information and is relative to what people believe or think. When we think of justification, we think of it in terms of justifying something to other people. The stronger the justification, the stronger the argument, and therefore, the more value it has, when compared to other arguments. Knowledge that can be justified is more significant because it is more widely accepted. It shows that your case is logical and has reason. Society greatly values logic and reason as a way of knowing. This makes the information more credible, and gives it more meaning. An example of how this sort of knowledge is respected is to take a look at the foundations of sciences and mathematics, which hold much value in our world today. The theories that they consist of are based on strong justifications that have been refined over decades of study and research. You may ask, “What makes a justification strong or weak? How are we to decide whether the information is valuable?”. Justification consists of the evidence or proof that supports the information. Scientists provided evidence for their theories which strengthened their cases. For example, the development of the structure of an electron was based on evidence that proved that they existed. In 1897, J. J. Thomson found that cathode rays were bent in certain directions by electric and magnetic fields, and therefore, he...
