Where is the giant's shoulder?

Samuel Taylor Coleridge, in The Friend (1828), wrote:
"The dwarf sees farther than the giant, when he has the giant's shoulder to mount on."
That mean "One who develops future intellectual pursuits by understanding the research and works created by notable thinkers of the past";
If you want to see further, first you should find the giant, second you should find the shoulder of the giant,third you should mount on the shoulder.
For dwarf , maybe it's not so easy to do these stuff.. But it's a good way to see further than anyone before.
For me ,as a dwarf, just starting to think this...Work hard ,and mount on the shoulder of giant.
