Which ideal was so important to French revolutionaries that it was used in slogans--but not mentioned by the American colonists in their revolutionary documents?

"liberty, equality, fraternity"

"Liberty, equality, fraternity" was the main slogan of the French revolution and although the American revolution wanted these same things and was impacted by the concepts developed in the French revolution, this slogan was not documented in American documents, probably because it was something very connected to the French territory and there was no interest in documenting it and establishing a connection between maerica and Europe.
