The present essay is about the understanding of under determination thesis in conjunction with the realism and instrumentalism.As we know that realism and instrumentalism are two opposite views in philosophy of science,so by explaining the two it would be much easier to grasp the concept of under determination thesis,which is one of complex doctrine.
The intended audiences of this essay are science student's and people who are interested to know about the philosophical issues in science.I divide the essay into four of parts.The first part explains the realism and instrumentalism concepts,second part explains the under determination thesis in detail and then the third part will state the views of different philosophers about three schools of thoughts.The fourth and the final part conclude the whole argumentation
