Bullet-pointed summary of ideas Nature book by Ralph Waldo Emerson?

I think options b is correct

Emerson now tackles the difficult question of subjective truth and the impossibility of verifying the truth of external reality. It is not possible to prove absolutely that what our senses perceive is real. The average person — Emerson uses the carpenter as one example of such a person — doesn't want to know that what he thinks is real might be an illusion. However, whether or not nature exists as something distinct from ourselves remains definitively unanswerable.

After declaring that it makes no difference whether external reality exists or not, Emerson begins his discussion of idealism. His first point concerns visual changes and distortions caused by mechanical apparatuses, or by our physically changing the way we interact with our environment. These changes and distortions emphasize the separation between ourselves and nature, a separation that produces wonder and provides us with a sense of our own stability. We come to believe that although the world around us changes, in part due to our causing it to, we stay constant. As Emerson notes, "We are not built like a ship to be tossed, but like a house to stand."

Overall, Emerson asserts the power and importance of ideas. Again using a circle to symbolize the interrelated universe of people and nature, he emphasizes that the universal ideas grounding us in this world are products of a Supreme Being. A person who contemplates universal ideas gains new heights of understanding and, according to transcendental philosophy, transcends time and space to attain a metaphysical consciousness and immortality.
