EXPLANATIONS BELOW
Concept note-1: -What he really meant was that the American colonists, as a people, had the same rights of self-government as other peoples, and hence could declare independence, create new governments and assume their “separate and equal station” among other nations.
Concept note-2: -Without the phrase, Lincoln would only be talking about the survival of a specific place, the nation founded in 1776 (“that nation”). With the phrase – “or any nation so conceived or dedicated” he says the question is not just the survival of that nation – but any nation built on the same principles.
Concept note-3: -Lincoln means that in 1776, the founding fathers of America drafted the Declaration of Independence, stating that all men are created equal. This allusion helps Lincoln’s audience to connect to the speech, as the Declaration of Independence is a well known writing in American history.
