Simple ideas are the building blocks of knowledge and the difference in knowledge between people is determined by the number of simple ideas one has.
Knowledge can be divided into three groups, intuitive knowledge, demonstrative knowledge and sensitive knowledge. Intuitive knowledge entails the ability to recognize the agreement or disagreement of ideas, and it results into perfect certainty. This kind of knowledge is seldomly available to a human being since the person in possession of it is very sure and certain about his arguments (Quintas, Lefrere, & Jones, 1997). Demonstrative knowledge is the perception of agreement or disagreement through a series of simple ideas. For example, a person may know that mathematics is difficult than English and English is difficult that geography and hence they immediately know that mathematics is difficult than geography. Demonstrative knowledge is backed up by having very many simple ideas and relating them in order to come up with conclusions. Sensitive knowledge is caused by the ability to use body senses and have an idea of something even if the cause is unknown to the person. An example of such occasion is when one knows that there is a sweet smell, but they don’t know what’s causing it.
Knowledge can also be defined as the relationship between mental objects in the mind of a conceptualizer who is an intelligent human being (Simonin, 2004). Knowledge is hence subjective and must not necessarily have any absolute meaning. Knowledge can also be defined as the intellectual patterns that lead to the existence of external reality. Knowledge differs between many people since it is what an individual’s mind accepts as true, and it gives that individual the ability to distinguish true from none-true.
