“..."Nature" is not to be understood as that which is just present-at-hand, nor as the power of Nature. The wood is a forest of timber, the mountain a quarry of rock; the river is water-power, the wind is wind 'in the sails'. As the 'environment' is discovered, the 'Nature' thus discovered is encountered too. If its kind of Being as ready-to-hand is disregarded, this 'Nature' itself can be discovered and defined simply in its pure presence-at-hand. But when this happens, the Nature which 'stirs and strives', which assails us and enthralls us as landscape, remains hidden. The botanist's plants are not the flowers of the hedgerow; the 'source' which the geographer establishes for a river is not the 'springhead in the dale'.”

“I can discover nothing in any mere animal but an ingenious machine, to which nature has given senses to wind itself up, and guard, to a certain degree, against everything that might destroy or disorder it.”

“At the end of the day, no amount of investing, no amount of clean electrons, no amount of energy efficiency will save the natural world if we are not paying attention to it - if we are not paying attention to all the things that nature give us for free: clean air, clean water, breathtaking vistas, mountains for skiing, rivers for fishing, oceans for sailing, sunsets for poets, and landscapes for painters. What good is it to have wind-powered lights to brighten the night if you can't see anything green during the day? Just because we can't sell shares in nature doesn't mean it has no value.”

“Nature consists of facts and of regularities, and is in itself neither moral nor immoral. It is we who impose our standards upon nature, and who in this way introduce morals into the natural world, in spite the fact that we are part of this world. We are products of nature, but nature has made us together with our power of altering the world, of foreseeing and of planning for the future, and of making far-reaching decisions for which we are morally responsible. Yet, responsibility, decisions, enter the world of nature only with us”

“When man becomes greater than nature, nature, which gave us birth, will respond.”

“Now a work of art is a work of nature, but it is a work of human nature. It is a work of the mind: and it's a work of the mind in circumstances for an occasion which, to which, for which, and which it may be supremely natural and simple and effective."The Nature of Art" December 19, 1954”
