It is not a body of doctrine resting upon the authority of persons. It is not the mere pursuit of gadgets, though gadgets in their variety have resulted from the advancement of scientific knowledge. Science is a way of enquiring. It is a method of advancing knowledge about those happenings that can be seen and measured. In a sense we are wrong in talking of science as if it existed by itself.
Science is only the name for a human activity.
Science is only the work and findings of scientists. It is not a sausage machine grinding out relentless results. Scientists are humans like others, but they happen to be humans with special interests and abilities, just as other humans in other walks of life have their special interests and abilities. Like all other humans they too are fallible and prey to their emotions, ambitions and greed. Scientists sometimes do err - unconsciously and on purpose.
