The Enlightenment, 17th to 18th centuries, focused on reason and science to improve society.

00:15.200 --> 00:20.880
Thinkers like Isaac Newton, with his Principia Mathematica, advanced our understanding of

00:20.880 --> 00:26.680
physics and astronomy through empirical evidence and the scientific method.

00:26.680 --> 00:32.040
He was central to the Enlightenment, with philosophers advocating for natural rights,

00:32.040 --> 00:36.640
like freedom of speech, religion, and property.

00:36.640 --> 00:41.760
John Locke's two treatises of government argued that governments should protect these

00:41.760 --> 00:47.440
rights and that people could overthrow those that failed to do so.

00:47.440 --> 00:53.640
Enlightenment thinkers challenged absolute monarchy, advocating for democracy and consent-based

00:53.640 --> 00:55.880
government authority.

00:55.880 --> 01:01.040
John Locke Rousseau's The Social Contract argued that legitimate authority arises from

01:01.040 --> 01:05.240
a mutual agreement among citizens.

01:05.240 --> 01:10.240
Enlightenment philosophers propose separating government powers into different branches

01:10.240 --> 01:14.960
with checks and balances to prevent tyranny.

01:14.960 --> 01:22.280
Montesquieu's The Spirit of the Laws outlined this idea, influencing modern democratic systems.

01:22.280 --> 01:28.720
Key figures of the Enlightenment included Voltaire, whose sharp wit and criticism of societal

01:28.720 --> 01:36.400
and religious institutions are captured in his satirical work Candide.

01:36.400 --> 01:43.120
Emmanuel Cain, another prominent philosopher, emphasized the role of reason and morality and

01:43.120 --> 01:50.240
urged individuals to think independently in his essay, What is Enlightenment?

01:50.240 --> 01:56.680
Lastly, Adam Smith laid the foundations of modern economics with his book The Wealth of

01:56.680 --> 02:03.480
Nations, which introduced the concept of the invisible hand and the benefits of free markets.

02:03.480 --> 02:09.320
Together, these ideas and figures transformed the intellectual landscape, laying the

02:09.320 --> 02:12.680
groundwork for modern democratic and scientific thought.
