Meaning "the intellectual side of civilization" is from 1805; that of "collective customs and achievements of a people" is from 1867.

Dividing the quote may highlight a particular nuance of the quote’s meaning. In the first example, the division calls attention to the two parts of Hamlet’s claim. The first phrase states that nothing is inherently good or bad; the second phrase suggests that our perspective causes things to become good or bad. In the second example, the isolation of “Death thou shalt die” at the end of the sentence draws a reader’s attention to that phrase in particular. As you decide whether or not you want to break up a quote, you should consider the shift in emphasis that the division might create.
