Usually the keenest appreciation of what is seen in nature is to be found in those who have also profited by the hoarded and recorded wisdom of their fellow-men. Love of outdoor life, love of simple and hardy pastimes, can be gratified by men and women who do not possess large means, and who work hard

Context

“Nevertheless among those men whom I have known the love of books and the love of outdoors, in their highest expressions, have usually gone hand in hand. It is an affectation for the man who is praising outdoors to sneer at books. Usually the keenest appreciation of what is seen in nature is to be found in those who have also profited by the hoarded and recorded wisdom of their fellow-men. Love of outdoor life, love of simple and hardy pastimes, can be gratified by men and women who do not possess large means, and who work hard; and so can love of good books—not of good bindings and of first editions, excellent enough in their way but sheer luxuries—I mean love of reading books, owning them if possible of course, but, if that is not possible, getting them from a circulating library.” source
