From Adams first day on earth, information and beliefs have been conveyed through and to every man to orient us in this world. It is from these beliefs and information that provide realization for our knowledge to offspring. Plato's version of belief is concerned with the changing (especially the material world), and knowledge with the unchanging (e.g. mathematics). Other versions might suggest that we can have knowledge of our surroundings, but only when some physical thing is directly present to the mind. So knowledge is a direct relation, while belief is conceived as an indirect relation to the thing believed and the study of human knowledge is known as Epistomology. In some areas, we might say, knowledge is available, and in others it is not - or at least it is less freely available. The problems that epistemology faces revolve around the determination of the truth which all sources of knowledge fail to completely justify. Every form of knowledge whether it is gained through senses, authority, science, intuition or rationality has significant problems, which creates doubts in regards to the truth. .
Descartes, a highly regarded philosopher, once argued that we cannot know something if we are unable to distinguish the case where it is true from the case where, though false, it seems to be true. For if we cannot distinguish, then though it may here be true, for all we know it is not; this case might, for all we can tell, be one where the appearances are deceiving us, and if so we can hardly claim to know that they are not. .
Empirical or sense experienced knowledge is a fundamental source where knowledge is acquired through the senses. The five senses which consist of distant (smell, hear, and sight) and classical (touch and taste) senses encounter many problems in justifying that all knowledge from the senses is the truth. Emperiests believe the only way of getting information about the outside world is via the senses.
