Tinker Quotes (6 quotes)
The first rule of intelligent tinkering is to save all the parts.
With co-author John P. Holdren, in Saturday Review (5 June 1971), 54, 59. Ehrlich is making his own paraphrase of an earlier quote, citing Aldo Leopold: “To keep every cog and wheel is the first precaution of intelligent tinkering.” See the Aldo Leopold Quotes page of this website. These refer to the importance of supporting an ecosystem by keeping all its parts - saving all the species.
The human mechanism is marvelous. But why not—it is the result of three-and-a-half billion years of tinkering.
Epigraph in Isaac Asimov’s Book of Science and Nature Quotations (1988), 12.
Through most of his existence man’s survival depended on his ability to cope with nature. If the mind evolved as an aid in human survival it was primarily as an instrument for the mastery of nature. The mind is still at its best when tinkering with the mathematics that rule nature.
In Before the Sabbath (1979), 26.
To save every cog and wheel is the first precaution of intelligent tinkering.
From 'Conservation' (c.1938), Round River: From the Journals of Aldo Leopold (1953), 146-147. Collected in The Essential Aldo Leopold: Quotations and Commentaries (1999), 142.
We live in a capitalist economy, and I have no particular objection to honorable self-interest. We cannot hope to make the needed, drastic improvement in primary and secondary education without a dramatic restructuring of salaries. In my opinion, you cannot pay a good teacher enough money to recompense the value of talent applied to the education of young children. I teach an hour or two a day to tolerably well-behaved near-adults–and I come home exhausted. By what possible argument are my services worth more in salary than those of a secondary-school teacher with six classes a day, little prestige, less support, massive problems of discipline, and a fundamental role in shaping minds. (In comparison, I only tinker with intellects already largely formed.)

Why then be concerned about the conservation of wildlife when for all practical purposes we would be much better off if humans and their domestic animals and pets were the only living creatures on the face of the earth? There is no obvious and demolishing answer to this rather doubtful logic although in practice the destruction of all wild animals would certainly bring devastating changes to our existence on this planet as we know it today… The trouble is that everything in nature is completely interdependent. Tinker with one part of it and the repercussions ripple out in all directions… Wildlife—and that includes everything from microbes to blue whales and from a fungus to a redwood tree—has been so much part of life on the earth that we are inclined to take its continued existence for granted… Yet the wildlife of the world is disappearing, not because of a malicious and deliberate policy of slaughter and extermination, but simply because of a general and widespread ignorance and neglect.
World Wildlife Fund Dinner, York, (1969). As quoted and cited in 'The Mirror of a Duke', The Dorset Eye on dorseteye.com website
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
