“How can we understand the world we find ourselves in? » In The Grand Design, a 2010 book written by theoretical physicist Stephen Hawking and Leonard Mlodinow, two authors claim to have found a philosophical approach – model-dependent realism (MDR) – as a solution to this fundamental question in philosophy. By combining ideas from the methodology of mathematics and physics, MDR opens a possible path to reconciling the uncertain nature of modern science and the idealistic pursuit of absolute truth – perhaps the Theory of Everything (TOE). According to Hawking and Leonard, Model Dependent Realism “is based on the idea that our brain interprets information from our sense organs by creating a model of the world. When such a model succeeds in explaining events, we tend to attribute to it, as well as to the elements and concepts that constitute it, the quality of reality or absolute truth. » The development of the MDRS Several hypothetical models explaining the same event could exist at the same time with equal legitimacy. This is called alternate reality. “There can be different ways of modeling the same physical situation,” explains Stephen Hawking, “each employing different fundamental elements and concepts.” For example, the legend that a giant wolf eats the moon and the theory that the moon is covered by the earth's shadow explain the eclipse phenomenon, and "if two of these physical theories or models accurately predict the same events,” Hawking explains: “One cannot be said to be more real than the other; rather, we are free to use the model that suits us best. » The idea of ​​alternative reality calls into question the principle of contradiction, a fundamental element of logic which is found...... middle of paper ...... that "they must have been used to hold without exception – if not universally. The precision rule requires that models make predictions as specific as possible so that future observations can disprove or falsify the model. Although the use of MDR is inevitable in the modern philosophical context, it still has some flaws that should not be. neglected. Most important of all is that, although titled Realism, MDR produces educated guesses at best. In a sense, the scientific method and model-dependent realism are like riding a wild horse. When one puts on a saddle and mounts, the horse may appear to follow its will by running in its assigned direction, but it is indeed possible that this is not the case, because the horse has a mind of its own . Model-dependent realists must avoid overconfidence by keeping in mind that models are only artificial..
