Some people think that it never will be able to do this, though scientific knowledge sometimes warns us in advance of the consequences of our choices. Science is not the mere accumulation of encyclopaedic knowledge. It is not exactly common sense - at least as far as some of its conclusions are concerned. 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.
