Criticism is Doing You a Favor

[N]o scientist likes to be criticized. ... But you don't reply to critics: "Wait a minute, wait a minute; this is a really good idea. I'm very fond of it. It's done you no harm. Please don't attack it." That's not the way it goes. The hard but just rule is that if the ideas don't work, you must throw them away. Don't waste any neurons on what doesn't work. Devote those neurons to new ideas that better explain the data. Valid criticism is doing you a favor.

 There is No Scientific Basis for Prejudice

Break the chains of your prejudices and take up the torch of experience, and you will honour nature in the way she deserves, instead of drawing derogatory conclusions from the ignorance in which she has left you. Simply open your eyes and ignore what you cannot understand, and you will see that a labourer whose mind and knowledge extend no further than the edges of his furrow is no different essentially from the greatest genius, as would have been proved by dissecting the brains of Descartes ...

 Where Scientific Ideas Come From

No Geologist worth anything is permanently bound to a desk or laboratory, but the charming notion that true science can only be based on unbiased observation of nature in the raw is mythology. Creative work, in geology and anywhere else, is interaction and synthesis: half-baked ideas from a bar room, rocks in the field, chains of thought from lonely walks, numbers squeezed from rocks in a laboratory, numbers from a calculator riveted to a desk, fancy equipment usually malfunctioning on expens...

 Darwin and Abraham Lincoln Were Born on the Same Day

Charles Darwin (fig. 4.1) was bom on the same day as Abraham Lincoln—February 12,1809. Like Lincoln, he was a liberating force for humankind, but instead of freeing people from slavery, he freed biology from the bondage of supernaturalism. Philosophers of science have long pointed to Darwinian evolution as the greatest scientific revolution within biology, comparable to the role of Newton's or Einstein's revolutionary ideas in physics or the plate tectonics revolution in geology. Before Dar...

 The Immensity of Time

How many times did the sun shine, how many times did the wind howl over the desolate tundras, over the bleak immensity of the Siberian taigas, over the brown deserts where the Earth's salt shines, over the high peaks capped with silver, over the shivering jungles, over the undulating forests of the tropics! Day after day, through infinite time, the scenery has changed in imperceptible features. Let us smile at the illusion of eternity that appears in these things, and while so many temporary ...

 Freedom

The morning comes, the night decays, the watchmen leave their stations; The grave is burst, the spices shed, the linen wrapped up; The bones of death, the cov’ring clay, the sinews shrunk & dry’d Reviving shake, inspiring move, breathing, awakening, Spring like redeemed captives when their bonds & bars are burst. Let the slave grinding at the mill run out into the field, Let him look up into the heavens & laugh in the bright air; Let the inchained soul, shut up in darkness and...

 Our Responsibility as Scientists

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. There are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions and pass them on. It is our responsibility to leave the men of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now, so young a...
