When you read a text and want to decide what the author's purpose for writing it was, then you need to take a look at the evidence he or she presented, as well as whether or not that evidence was appropriate. What is irrelevant here, however, is how fast or how slow you read the text - that has nothing to do with the author's purpose.
What it means is that he wouldn't have been able to get where he got if it hadn't been for the scientific achievements of his predecessors. If it hadn't been for these "giants" that enabled him to see so far, he wouldn't have been able to make all the discoveries that he did. For those coming after him, he was a giant that enabled them, and so laws and theories and scientific knowledge always increases based on the knowledge before it.
