Henry David Thoreau (1817-1862) was an American writer, thinker, naturalist, and leading transcendental philosopher. Graduating from Harvard, Thoreau's academic fortitude inspired much of his political thought and lead to him being an early and unequivocal adopter of the abolition movement. This ideology inspired his writing of Civil Disobedience and countless other works that contributed to his influence on society. Inspired by the principals of transcendental philosophy and desiring to experience spiritual awakening and enlightenment through nature, Thoreau worked hard at reforming his previous self into a man of immeasurable self-sufficiency and contentment. It was through Thoreau's dedicated pursuit of knowledge that some of the most iconic works on transcendentalism were created.
