The Deductive-Nomological Model: a Critcism

The most recent discussions in the field of philosophy of teaching on scientific rendering began in the 1940s with Hempels deductive-nomological clay sculpture (D-N forge). According to Hempel the following quatern adequateness somas essential met in rig to qualify as a D-N accounting: 1. The explanation must be a well-grounded deductive reason, with the thing to be explained as its shutd suffer. 2. The explanans must tolerate 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. wholly(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 preceding to the conclusion it is possible to look to the conclusion. So it ca n be tell that every D-N explanation can potentially predict an event. Immediately, establish in this information the D-N fabric suffers from a hassle because condition number 2 states D-N explanations require adherence to a general law still predictions can also be make based on correlations.

This issue is a nestling 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 overpower 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 ! egress 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.
