ABSTRACT
Consider medical science. Checking a person up from out-
side, feeling his pulse or listening to the nature of his cough
— it is quite possible to diagnose certain diseases and even
treat them. However could a doctor be satisfied with just
that? He cannot and indeed he should not. He needs to
know the details of the mechanism working inside a hu-
man body — from the location of the brain or the liver to
the functioning of the lungs — only then would he be able
to treat a serious condition.
