“Words, even the most ephemeral ones are facts, as heavy as fetters, they leave deep marks.”

“Non pretendo di scoprire l'acqua benedetta calda, ma la religione è una forma di controllo e di oppressione che va bene per le masse. Pertanto, un perfetto Gentiluomo, che è assolutamente democratico e conservatore dove sarebbe inutile non esserlo, sa che le masse si meritano di essere controllate e oppresse: lui no.”

“No matter how intently one studies the hundred little dramas of the woods and meadows, one can never learn all the salient facts about any one of them.”

“One of the penalties of an ecological education is that one lives alone in a world of wounds. Much of the damage inflicted on land is quite invisible to laymen. An ecologist must either harden his shell and make believe that the consequences of science are none of his business, or he must be the doctor who sees the marks of death in a community that believes itself well and does not want to be told otherwise.”

“Ethical behavior is doing the right thing when no one else is watching- even when doing the wrong thing is legal.”

“The three species of pine native to Wisconsin (white, red and jack) differ radically in their opinions about marriageable age. The precocious jackpine sometimes bloom and bears cones a year or two after leaving the nursery, and a few of my 13-year-old jacks already boast of grandchildren. My 13-year-old reds first bloomed this year, but my whites have not yet bloomed; they adhere closely to the Anglo-Saxon doctrine of free, white, and twenty-one.”

“Wilderness is a resource which can shrink but not grow... creation of new wilderness in the full sense of the word is impossible.”
