My current reading. The language is dated, but there are themes that are very very current in debates I'm reading now about conservation, society and consumerism among other things.
These from an interesting passage about life and experience...
"Age is no better, hardly well, qualified for an instructor as yout, for it has not profited as much as it has lost."
"Man's capacities have never been measured; nor ar we to judge of what he can do by any precedents, so little has been tried."
"Whatever have been thy faliures hitherto, 'be not afflicted, my child, for who shall assign to thee what thou hast left undone'."
Walden: or life in the woods. Henry David Thoreau
