Knowledge can be defined as the fact or state of knowing. There are many different aspects of knowledge. Knowledge comes from many different places. There are great numbers of philosophers who have tried to describe where knowledge comes from. Also knowledge can be divided into different parts according to the way we receive knowledge. There are many things that related to the knowledge of something. The development of questions in philosophy about knowledge began back in the day of Plato. They are still around today. These questions are the hardest to answer. Also these questions are used to give background on a lot of philosophies. Epistemology is the theory of knowledge. This theory asks three questions: what are the sources of knowledge? What is the nature of knowledge? And is our knowledge valid?
Knowledge is believed to come from four different sources. The sources each have their own away to look at the world. The appeal to authority is the first source of knowledge. We learn thing about the past from the testimony of others. The experience of the person who gives you the testimony is the actual source. Although authority is used a lot as a source of knowledge, this is only a secondary source.
Another source is the senses through empiricism. The realm of knowledge is given to us through all of our perceptions of something concrete. Whatever someone sees, hears touches, smells, and tastes then is made into an idea that becomes a part of the knowledge that person can receive. The philosophy of pragmatism is similar to empiricism.
The next source is rationalism. Rationalists say that thinking is a source of knowledge. They also say that the mind has the ability to discover truth by itself, or knowledge is obtained by comparing ideas with ideas. The things that the senses detect are just raw material of knowledge in rationalism.
The last source is intuition, or the direct apprehension of knowledge that is not the result of conscious reasoning or of immediate senses perception. Intuition has four different ways that is connected with being a source of knowledge. First George Santayana believed intuition was the awareness of the immediate data of consciousness. He said that intuition is in the knowledge of oneself and one’s own life .The second is that intuition is actually just a combination of one’s past experiences and thinking. It comes from subconscious induction or education. People who have done a lot of thinking and have done a certain type of work will have a good intuition in that area. The belief that intuition is a higher kind of knowledge is the third way it could be source. Bergson said that intelligence and intuition are travelling in opposite directions. Intelligence is tool used by science to deal with matter, while intuition is the instinct of someone that leads person to the very inwardness of life.
The last way intuition could be a source of knowledge is through mystical expressions. It is believed that mystical expressions can enable someone to gain an immediate knowledge that transcends knowledge gained through reason and the senses. This fourth description of intuition says that it could be a manifestation of the self in union with spiritual reality. These sources of knowledge range from the very perception of objects to the supernatural induction of knowledge.
Knowledge does not only have its sources but it also can come from different natures. The two main natures of knowledge are subjectivism and objectivism. Other than the nature of knowledge there are two types of knowledge. These types are associated into both natures. Subjectivism is the belief that thing do not exist without a preconception of the object. Through consciousness we can find reality. The dreams, hallucinations, and illusions that a person has are all part of subjectivism. These thing that a person experiences are not physical in the outside world making them a part of the experiences in the mind. Locke described the colour, sound, taste, odour, and so on of an object to not belong to that object in the outside world. He called these secondary qualities very form person to person. Later after Locke had problems getting around the notion of “material substances”, Berkeley stated that all qualities, both primary and secondary, are in the mind therefore matter does not exist. More recent subjectivists have said that we cannot get outside our own experiences.
