One definition of knowledge is true belief based on strong evidence. What makes evidence

Extracts from this document...

Introduction

Scott Donnelly 4. One definition of knowledge is true belief based on strong evidence. What makes evidence "strong" enough and how can this limit be established? Truth is the essence of all knowledge. Our Knowledge is justified true belief. Everyday people hear and experience things and then choose whether or not to believe them. It is the justification of the knowledge that we acquire that makes something believable to a person or not. The justification for our knowledge allows us to decide whether to believe something is true or not. People tend to use things like scientific evidence, first hand experiences, word of mouth, logic, faith and many other things everyday of their life to determine whether something is truthful or not. Before continuing, it is important that it is stated that nothing should be taken for truth simply because it is written by any particular person. The statements in this text are no exception. This text, along with other statements, should be judged only by whether they are consistent with evidence or logic. Even if there are many examples of proven truths in this texts, that does not mean all statements in this text are true. The most common source of knowledge is experience. People are constantly acquiring knowledge through their senses. Someone can see something to determine if a statement or idea is true or not. ...read more.

So, without any experience or scientific reason to believe in a superior being, why is it that people have faith. Most people base their belief on authority. An authority has told them once that God exists, so they believe it. Whether the authority figure is a priest, their parents, the government, a friend they trust or simply a book they have read, it does not matter. The fact is, this authority figure has placed this idea in their head, and now they believe it. They likely believe it because they trust this person's opinion, and they believe it to be true, therefore it must be true. This is not evidence, but for some people it is enough to make them believe something is true. Authority is a source of knowledge for things other than religion as well, but it is obviously not the strongest evidence of truth. Another reason for someone to have faith in God is that they simply cannot believe that God does not exist. Though faith is often tied with belief in God, it can also be associated with beliefs in other things as well. People have faith in such beliefs as Santa Claus, or the Tooth Fairy. These beliefs have nothing to do with logic, and supernatural ideas such as these cannot be proved or disproved by science. ...read more.

Conclusion

Different people percieve these things in different ways, that makes it difficult to find any certainty of truth in ethics. Though all of these sources of knowlegde seem to sometimes be strong enough to prove that a statement or idea is true (or something that you know) it is not. All of these things can be proved wrong. Everything that any person has experienced, perceived or deduced throughout a lifetime can be proved wrong. This is possible with the simple idea that the world we live in could be a deception, an illusion. The only thing that can be proven to be completely true is that I, myself, exist. Descartes proved this with the statement "I think, therefore I am". This allows me to prove to myself that I do exist, because if I do not exist I could not have come to this conclusion. To conclude, the problem with attempting to prove a theory of truth, is that there can be no theories of truth. This is because truth is required for a theory of anything. No theory can exist without truth. Every "proven" statement of every theory is based on the implication that it is true. So we may believe things to be true, because of scientific proofs, experience or just because we believe, but most of these "truths" cannot be backed up by strong enough evidence to prove that they are completely true. ...read more.
