Skepticism is an attitude of doubting knowledge claim set forth in various areas. It challenges the adequacy and reliability of such claims by questioning what principles they are based on and what they establish. David Hume attempts to undermine human rationality to ascent the existence of cause and effect through his work An Enquiry Concerning Human Understanding. He starts by illustrating the differences between ideas and impression, arguing that impression arise through emotions, senses and other psychological incidences while ideas are thoughts memories and beliefs that result to impression. According to Hume, the human construct ideas in three different ways including continuity, cause and effect and resemblance. Human knowledge comprises of two fundamental’s forms; matters of facts and relations of ideas. He noted that relations of ideas are derived from contemplation of ideas that are related to a pure rational state without the need of empirical prove or use of sense data. Matters of facts is developed from empirical observation made nature, arguing that there is always the possibility of contrary of every matter under consideration (Hume, 2000, p. 28).

After illustrating the differences between matters of facts and relation of ideas, Hume continued to apply the knowledge in the concept of cause and effect. Through experience, causes and effects are discoverable on the basis of the analytically and observation derive knowledge. He places causes and effects on the knowledge that is gained through observation. He gives an example of a billiard-ball presented to an observer who has never had such as experience. The observer will never understand the effect because it is totally different from the cause. The only way a person can understand billiard-ball is through observation. Hume claims that the only it is through experience that an individual can understand the cause of a certain phenomenon associated with illusion after the connection is established through observation. A connection is established between the minds the mind and the custom associated with past observation. The connection is made from irrational projection from earlier experience associated with future events and assumptions that the future will resemble past events (Hume, 2000, p. 31).


There is not present concept including the geometry science can explain the ultimate cause of the experience despite being accurate in its way of thinking.
