Description

Belief revision is the process of changing beliefs to take into account a new piece of information. The logical formalization of belief revision is researched in philosophy, in databases, and in artificial intelligence for the design of rational agents.

What makes belief revision non-trivial is that several different ways for performing this operation may be possible. For example, if the current knowledge includes the three facts "A is true", "B is true" and "if A and B are true then C is true", the introduction of the new information "C is false" can be done preserving consistency only by removing at least one of the three facts. In this case, there are at least three different ways for performing revision. In general, there may be several different ways for changing knowledge.

In historiography, historical revisionism is the reinterpretation of orthodox views on evidence, motivations, and decision-making processes surrounding a historical event. Though the word revisionism is sometimes used in a negative way, constant revision of history is part of the normal scholarly process of writing history.

Quote

When knowledge is acquired, it is first a concept. A concept that may be new or a concept that has its beginnings from previous information. When a new concept is presented, the mind searches for a correlating concept or information regarding this new concept. When no new information is retrieved from memory, then confusion arises and then an element of fear, yes ambivalence for the new information. This is a normal process. When knowledge of new information comes forth, the determined outcome of the new information is already formed in the perceived knowledge. So you can see that new information requires overcoming the inherent elements of the reactive physical being and something else, a new element is required. Humans have this phrase, "open mind", and upon examination of this state of mind, one will notice the ability to set aside previous concepts inherent in this action and absorb the new knowledge. So, here we are dissecting this process and the element of open mindedness which is called many things, but foremost should be truth. - JarEl
