Leaders of thought, be they scientists or not, however, occasi¬onally pause and ponder whether science is going the right way and really promoting human welfare. A dispassionate and comprehen¬sive survey of the fruits of scientific advance in the various spheres of human life provides sufficient ground to be sceptical about the claim that science is an unqualified and unmixed blessing to huma¬nity. They have reason to conclude that all is not well with science and its application.
Pure science is a relentless search for truth, for the discovery of the laws of nature. As such, no fault finding is possible with pure scientific research. The position, however, changes materially in regard to the application of scientific research in the field of practi¬cal activity. Science is like a sharp sword which can be used for either defending yourself against the enemy or cutting your own throat. What the pure scientist gives to his fellow-beings may thus be turned to their advantage, or exploited for subversive and des¬tructive purposes. The application of science, therefore, depends upon the just or unjust aims man has in view, and the history of the world shows that the application of science has not always been governed by principles of justice and consideration of the generanl good of the people.
