Abstract
From the Scientific Revolution to the present era, the natural sciences have developed remarkably and recorded colossal success in different areas such as genetic engineering, cloning, hybrid technology, health and food technologies, space travel, audio-visual technology, among others. These evidences are indications of the growth of scientific knowledge. Accordingly, this paper raises the question of what is responsible for the growth of scientific knowledge. Inherent in this question is the pool of diverse conceptions of what the nature and method of science is. Consequently, some significant contours in the construct of the problem of demarcation will be imported into this discourse as a means of assembling some pivotal conceptions of the growth of scientific knowledge. With this, the paper aims to consider Karl Popper’s fundamental conception of the growth of scientific knowledge and its associated criticisms, and from it, attempt to respond to the question of what is responsible for the growth of scientific knowledge. This will help to eliminate the confusion and complications surrounding the growth of scientific knowledge.
