In approaching a problem a Marxist should see the whole as well as the parts. A frog in a well says, "The sky is no bigger than the mouth of the well." That is untrue, for the sky is not just the size of the mouth of the well. If it said, "A part of the sky is the size of the mouth of a well", that would be true, for it tallies with the facts.
