“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.”

“We shall never achieve harmony with the land, anymore than we shall achieve absolute justice or liberty for people. In these higher aspirations the important thing is not to achieve but to strive.”

“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.”

“A thing is right when it tends to preserve the integrity, stability and beauty of the biotic community. It is wrong when it tends otherwise.”

“I am convinced that most Americans of the new generation have no idea what a decent forest looks like. The only way to tell them is to show them.”

“Conservation is a state of harmony between men and land.”

“Is education possibly a process of trading awareness for things of lesser worth? The goose who trades his is soon a pile of feathers.”

“In June as many as a dozen species may burst their buds on a single day. No man can heed all of these anniversaries no man can ignore all of them. ”

“One of the anomalies of modern ecology is the creation of two groups, each of which seems barely aware of the existence of the other. The one studies the human community, almost as if it were a separate entity, and calls its findings sociology, economics and history. The other studies the plant and animal community and comfortably relegates the hodge-podge of politics to the liberal arts. The inevitable fusion of these two lines of thought will, perhaps, constitute the outstanding advance of this century.”

“Do not let anyone tell you that these people made work of play. They simply realized that the most fun lies in seeing and studying the unknown.”

“Examine each question in terms of what is ethically and aesthetically right, as well as what is economically expedient. A thing is right when it tends to perserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise.”
