Start with clarifying your terms. There were 3 drastically different Enlightenments: The Roads to Modernity: The British, French, and American Enlightenments by Gertrude Himmelfarb
, and the Scientific Revolution started by restricting reason. As to norms, Bacon said very pointedly: Aristotle's concept of "final cause" came under attack in the sixteenth century. Francis Bacon (1561–1626) led the attack against this notion. Indeed, Bacon was the lead propagandist against many aspects of the Aristotelian methodology for science.
I ask you: what is the NORM you are unconsciously applying be even asking this question? You aren't asking for what science thinks of norms or what the Enlightenment thinks of norms. You are asking for 'reason' and 'experience' to be your arbiter. And therefore, since our norms come from hundreds of millions of our forebears acting over thousands of years....well, Science and the Enlightenment should answer to THAT !!! .
