When humans become reasonable

2. Origins
Scientific Revolution: thinkers come up with new explanations of what was already believed.
Copernicus & Galileo: heliocentric model
Newton: Gravity and Physics
These thinkers challenged the established understanding and began coming up with their own theories based on reason.

3. What is reason? What do you think of when you hear the word “reason”?
Reason is the ability to use what exists to form conclusions, understanding and judgments on ones own.
What in the world does that mean?

4. Enlightenment
The scientific revolution thinkers challenged what was accepted and concluded something different using the facts around them.
Galileo uses the facts he sees (notices moons revolving around Jupiter) and concludes that smaller planetary bodies revolve around larger ones. Therefore, Copernicus was right, the Earth revolves around the Sun.

5. Enlightenment
New thinkers decide they can apply this reason to other areas of thought such as human nature and human society.
Using reason, humans can answer any question that plagued the human race.
However, these thinkers each reasoned differently when it came to these new issues.
