Science has created problems for mankind. Science is a blessing all right, but it is not an unmixed blessing. Science has made life easier and more comfortable.

But it is also a fact that this spirit, when carried to unreasonable lengths in an unimaginative manner, militates against the original intentions. The scientific method thus becomes misused. The spirit of positivism is exaggerated to such lengths that anything that is not proved by crude laboratory experiments is dismissed as superstition. A complacent world believing in the creation of man by God was shaken when Darwin came out with his theory of evolution and the origin of the species. Science makes us forgot that there is "much in philosophy than dreamt of in heaven and on earth."
The scientist would say that the most diabolical use of science has been in the cause of promoting the baser human instincts and that it is politicians and statesmen who are to blame for this. Man uses science and technology for purposes of aggression; he uses the discoveries of science to win wars. In the past men used only bows and arrows and swords to fight with one another. But today thanks to science, he ha. at his disposal guns, planes, ships, submarines, missiles, etc. The race for weapons has...
