White Pond and Walden are great crystals on the surface of the earth, Lakes of Light.... They are too pure to have a market value;they contain no muck. How much more beautiful than our lives, how much more transparent than our characters are they! We never learned meanness of them.

Books can only reveal us to ourselves, and as often as they do us this service we lay them aside.

We boast of our system of education, but why stop at schoolmasters and schoolhouses? We are all schoolmasters, and our schoolhouse is the universe. To attend chiefly to the desk or schoolhouse while we neglect the scenery in which it is placed is absurd. If we do not look out we shall find our find schoolhouse standing in a cow-yard at last.

Fire is the most tolerable third party

I, on my side, require of every writer, first or last, a simple and sincere account of his own life, and not merely what he has heard of other men's lives; some such account as he would send to his kindred from a distant land; for if he has lived sincerely, it must have been in a distant land to me.

While almost all men feel an attraction drawing them to society, few are attracted strongly to Nature. In their reaction to Naturemen appear to me for the most part, notwithstanding their arts, lower than the animals. It is not often a beautiful relation, as in the case of the animals. How little appreciation of the beauty of the landscape there is among us! We have to be told that the Greeks called the world Kosmos, Beauty, or Order, but we do not see clearly why they did so, and we esteem it at best only a curious philological fact.

Truths and roses have thorns about them.
