Idealism is the practice of forming unrealistic ideas. I like idealism because you can exaggerate events or stories in your life. It can also be unrealistic things that you may dream or imagine thats you think would be really awesome if they actually were realistic. You should like idealism because it brings joy and hope into your life. Idealism can also be bad unrealistic things like if the world blew up. its pretty much your imagination.
Transcendentalists don't mean beauty as in the way somebody looks or something looks. They mean beauty as in the beauty of nature and how it works. Beauty in nature is very interesting because you dont know how exactly things form in the way they do in nature it just happens. it is just amazing to watch what nature does over the years and how beautiful things turn out.
