If one doubts whether Grecian valor and patriotism are not a fiction of the poets, he may go to Athens and see still upon the walls of the temple of Minerva the circular marks made by the shields taken from the enemy in the Persian war, which were suspended there. We have not far to seek for living and unquestionable evidence. The very dust takes shape and confirms some story which we had read.
Henry David ThoreauThere is one thought for the field, another for the house. I would have my thoughts, like wild apples, to be food for walkers, and will not warrant them to be palatable if tasted in the house.
Henry David Thoreau
