One definition of knowledge is true belief based on strong evidence. What makes evidence "strong" enough and how can this limit be established? The making of knowledge is the process in which personal opinion is fortified by pragmatic evidence. It is to my belief that, evidence is a keystone in the justification of truth, because it is something solid and concrete. Significance of evidence is also magnified by our society as we develop. In major areas such as: scientific investigations, judicial examinations, historical assessments and many other field of knowledge, the value of creditable evidence are strongly advocated. While evidence is a strong factor in eliminating doubts of knowledge, different types of evidence can also affect the reliability of the truth claim which it supports.

The fine line dividing valuable evidence and unreliable proof has since been drawn and debated over from the first schools of thoughts to today's broad fields of knowledge. Likewise, I will also call upon my own experience and understanding to draw my own line in the grey vicinity of this spectrum. Before the declaration of my knowledge claims, I would like to clarify my understanding of evidence and its characteristics; which will be the foundation of this discussion. On a broad view, evidence can be identified as a fact-like assertion that proves or disproves.
