Henry David Thoreau was an American philosopher, poet, and writer. Many know him for his famous works such as, Walden, or Life in The Woods. Throreau was known to have strong belifes in the feilds of civil disobedience and transcendentalism.

“I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived. I did not wish to live what was not life, living is so dear; nor did I wish to practise resignation, unless it was quite necessary. I wanted to live deep and suck out all the marrow of life, to live so sturdily and Spartan-like as to put to rout all that was not life, to cut a broad swath and shave close, to drive life into a corner, and reduce it to its lowest terms."
