Which three topics became a major focus of the enlightenment?

I believe the Enlightenment period was also called the Age of Reason.

1. science- tying to understand the natural world and the reason why humanity was on earth without incorporating religion.

2. philosophy- writers who  looked at occurring events and tried to explain the causes of them through reasoning

3. Literature

4. The Arts- music paintings
