Thoreau is such an amazing philosopher, I decided that some time --and space-- needs to be dedicated to his thoughts.
One of the reasons H. Thoreau wrote his Walden is that he wanted to lessen that "gulf of ignorance." His advice on education is strikingly pragmatic. But the entire book can be viewed as a great metaphor carrying its latent educational message like that contained in the "The Pond in Winter" chapter:
If we knew all the laws of Nature, we should need only one fact, or the description of one actual phenomenon, to infer all the particular results at that point. Now we know only a few laws, and our result is vitiated, not, of course, by any confusion or irregularity in Nature, but by our ignorance of essential elements in the calculation. Our notions of law and harmony are commonly confined to those instances which we detect; but the harmony which results from a far greater number of seemingly conflicting, but really concurring, laws, which we have not detected, is still more wonderful. The particular laws are as our points of view, as, to the traveler, a mountain outline varies with every step, and it has an infinite number of profiles, though absolutely one form".
Here Thoreau expresses his quite modern opinion that the goal of an education should be the development of critical thinking, which would allow man to perceive the interrelatedness of phenomena. Today that goal remains the same.
He persued a teaching career, but left the school because he refused to administer corporal punishment. He never quit teaching, though. (Don't you wish you'd met him?)
To further quote Walden (my favorite excerpt!),
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 practice 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, and, if it proved to be mean, why then to get the whole and genuine meanness of it, and publish its meanness to the world; or if it were sublime, to know it by experience, and be able to give a true account of it in my next excursion.
It is clear that he, himself, believed that life was a pond to be jumped in. Oh, I really admire his philosophy. I hope this will inspire some thought.
