The fouth sources of knowledge mentioned first of empiricism rely on knowledge that is completely empirical in nature, they actually still have to be aware of the presence of various prejudices and feelings which also have the potential to distort their views when "choosing facts" which are considered to support the conclusions which is made. Empiricism, therefore, actually has several flaws that are sometimes deceptive. The limitation of our sense of sight when seeing an object that is actually large becomes small when looking at it from considerable distance; sees a straight object as if it were bent when it is placed in water; tasting sugar as bitter when sick with malaria; those are some examples that show the weakness and limitation of the senses on which empiricism rests. The second is Rationalisms, on the other hand, also have their drawbacks. Because excess makes reason power, rationalism has the potential to claim that they are capable of attaining undeniable truths that are independent and have no connection to the senses (experience). The rationalists, in other words, claim to be able to present the ultimate truth by relying only on the power of thought. The thirth are intuition (illuminisionism) and revelation as sources of knowledge, apart from their positions which are equally valid as sources of knowledge, intuition (illuminisionism) and revelation cannot be put independently and independently when they are used as sources of knowledge. Without the support of the power of reason (rationalism) and empirical data (empiricism) intuition and revelation will easily lead people to claims that cannot be justified
