Evidentialism is applied in describing a simple common sense position that any controversial claims made should have a good evidence to back it up. In other words, a belief ought to be held firmly only if it has a lot of evidence whether the evidence will be held at all or at least given up easily in the event of conflicting evidence is a difference case. Nonevidentialism, on the other hand, is described as an event where one may not query the truth of the second hypothesis as presented by evidentialist argument against belief in God, but he or she will plainly and ardently rebuff the first hypothesis of the argument. William Kingdon Clifford was a known philosopher and a mathematician whose works placed much emphasis on philosophy as opposed to mathematics. Through his journal titled “contemporary review,” he emphasized on various ethics of belief. He was critical of the criteria applied in the analysis of facts, which elucidated how an idea could be held or defended. According to the journal, it was not sensible to decide on what to believe in without any kind of formulation or direction. In his works, hee concluded that it is wrong to believe, hold, and defend anything with no adequate proof to back it up. In this regard, he coined the term evidentialism to suggest any argument must have sufficient facts to support it. This philosophy can be narrowly linked to skepticism since it relies on empirical evidence to support an idea. Blaise Pascal, a Roman Catholic apologist in the 17 th century and famously known for his ‘warger argument’, claimed that the heart has its own reasons for which the reasons know nothing. He additionally described that truth cannot just be reasons or proof and therefore, reliability on faith is equally important in seeking truth. Blaise defended his religious viewpoint and knowledge on the reality of God’s existence, although he acknowledged the fact that it cannot be demonstrated. Blaise’s viewpoint could only be illustrated as fideism or as incredulity meaning the reliance on the belief rather than faith or reason to preserve and support a belief on something. On the other hand, as expressed above, evidentialism disproves fideism main beliefs and urges people at least to gather facts on a given principle. This paper therefore highlights the fundamental significance of reasons and justification as opposed to holding faith based beliefs that carry no reasoning. In essence, Clifford’s philosophies are better suited in the modern world than the philosophies of Blaise. Clifford’s Evidentialism William Clifford held on the belief that it was very wrong for someone to believe or argue on something without enough proof to back up the evidence. To Clifford and other atheist evidentialists, believing and arguing on something was senseless. Clifford applied an example of a man who had an out of order ship to give details on his philosophy. In the illustration, the man was of the view that the vessel was fine and went ahead to overlook the fact that the ship was really out of order and that it was safe for the travelers on board. He thought he would do the repairs later after the trip. The man sought to avoid the time that it would take to repair the vessel since it would cost hi
