The Deductive-Nomological Model: a Critcism

The most recent discussions in the field of philosophy of education on scientific rendering began in the 1940s with Hempels deductive-nomological clay sculpture (D-N forge). According to Hempel the following quatern enough somas essential met in assure to qualify as a D-N accounting: 1. The explanation essential be a legitimate deductive agate line, with the thing to be explained as its shutd feature. 2. The explanans must select at least one general law that is compulsory for the conclusion. 3. The explanans must take on empirical content that is testable. 4. The statements of the explanans must be true. 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 earlier to the conclusion it is possible to call off the conclusion. So it c an be tell that every D-N explanation can potentially predict an event. Immediately, establish in this information the D-N manakin suffers from a fuss because condition number 2 states D-N explanations require adherence to a general law exactly predictions can also be make based on correlations.

This issue is a small 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 big bucks syndrome have Trisomy 21. 2. Josh has Down syndrome. Jo sh has Trisomy 21. While this counterexampl! e satisfies the conditions of the D-N model it explains a cause using the printing 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.
