For most people, visual proofs act as the biggest source of knowledge. It is widely held that it is quite difficult to undermine what is seen with the naked eye. However, I certainly believe that empiricism or experience based on one’s senses cannot serve as the sole foundation of knowledge. A linear correlation between the vision and the conclusions so drawn cannot be a valid proof of truth. For instance, going by a very mundane example, if a person arrives at a murder scene and finds, besides the victim, another person holding a revolver in his hands, then going by the proof of his vision he may arrive that the conclusion that the person is the killer.
