The Deductive-Nomological Model: a Critcism

The most recent discussions in the field of philosophy of information on scientific rendering began in the 1940s with Hempels deductive-nomological clay sculpture (D-N forge). According to Hempel the following quatern adequacy somas essential met in rules of order to qualify as a D-N accounting: 1. The explanation mustiness be a legitimate deductive lineage, with the thing to be explained as its shutd witness. 2. The explanans must film at least one general law that is necessitate for the conclusion. 3. The explanans must take on empirical content that is testable. 4. The statements of the explanans must be true. on the whole(prenominal) four conditions when met are individually necessary and justifiably satisfactory to be considered scientific explanations so D-N explanations are scientific explanations. all D-N explanations are arguments that demonstrate that if the explanans are available anterior to the conclusion it is possible to prophesy the concl usion. So it can be tell that every D-N explanation can potentially predict an event. Immediately, establish in this information the D-N pretense suffers from a riddle because condition number 2 states D-N explanations require adherence to a general law barely predictions can also be make based on correlations.

This issue is a kidskin enumerate that does not negate the D-N model on its own; however, the problems for the D-N model do not stop there. Nowhere in the model does cause factor into an explanation. Consider this counterexample: 1. People with mountain syndrome have Trisomy 21. 2. Josh has Down syndrome. Josh has Trisomy 21. While! this counterexample satisfies the conditions of the D-N model it explains a cause using the heart rather than explaining the effect by means of the cause. This lack of account for causal influences makes this D-N argument assert into the realm of inaccuracy. Another problem that arises with the D-N model is when all four adequacy conditions can be satisfied but the explanation is clearly not a scientific explanation.
