My desire for knowledge is intermittent; but my desire to commune with the spirit of the universe, to be intoxicated with the fumes, call it, of that divine nectar, to bear my head through atmospheres and over heights unknown to my feet, is perennial and constant.

All good things are wild and free.

I realized a school doesn't need a School Committee or Trustees or Governors or lumber or approved textbooks. All a school needs is a mind that sends and minds that receive. I shall teach my own students how to teach themselves. My own school. No buildings. Break out of the classroom prison. All I need is SKY. The Universe can be my classroom - the great vast world of the Concord countryside.

We know but a few men, a great many coats and breeches.

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.

The English did not come to America from a mere love of adventure, nor to truck with or convert the savages, nor to hold offices under the crown, as the French to a great extent did, but to live in earnest and with freedom.

The gifts of Heaven are never quite gratuitous.
