If I have seen further, it is by standing on the shoulders of giants is correct as far as it goes, but it gives dullards the wrong idea. Those giants don't hoist you up there for a piggy back. You have to climb up them like a kitten that hasn't been fed yet, and the giants swat at you while you make the ascent. Once you're standing on their shoulders, you realize that the giants are drunk half the time and palsied the rest. They were only giants because you were so short. You can't see as far as you had hoped. There's a lot of work left to do.
Read the rest at Sippican Cottage. Great stuff.
