And this philosophical movement that is really tied to the Scientific Revolution is known as the Enlightenment. And just to have an example of the thinking during the Enlightenment, here is a passage from John Locke, who's considered one of the pillars of the Enlightenment. This is published in 1689. It's the second treatise concerning civil government. The state of nature has a law of nature to govern it, which obliges everyone. And reason, which is that law, so reason is the law of nature to govern it, teaches all mankind who will but consult it that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions. And when his own preservation comes not in competition, ought he as much as he can to preserve the rest of mankind and may not, unless it be to do justice on an offender, take away or impair the life or what tends to the preservation of the life, the liberty, health, limb, or goods of another.
