Abstract
The distinction between context of discovery and context of justification points out to the difference between the generation a new idea or hyphotesis and the testing of it. Although the distinction is attributed to Hans Reichenbach and Karl Popper, Larry Laudan argues that the history of distinction is dates back to the debates of scientific in the seventeenth century. While in the seventeenth and eighteenth centuries there was no need to distinguish between discovery and justification, in the twentieth century discovery and justification were considered two separate processes. In this paper,
it will be argued that the distinction between the context of discovery and justification is untenable given that the history of science is a part of scientific research, as expressed by philosophers such as Kuhn and Feyerabend.
