And if we must educate our poets and artists in science, we must educate our masters, labour and capital, in art.
An attempt to study the evolution of living organisms without reference to cytology would be as futile as an account of stellar evolution which ignored spectroscopy.
Interpretation
What this quote means
Studying life without understanding the cellular basis is ineffective, much like studying stars without knowing about their light properties.
In this quote, Haldane emphasizes the importance of understanding the fundamental building blocks of life, such as cells, in order to comprehend the broader concepts of biological evolution. He draws a parallel to astronomy, suggesting that studying stellar evolution without the insights gained from spectroscopy—the study of light—would also prove to be an inadequate approach. This highlights the interconnectedness of different scientific disciplines and the necessity of using all available tools and knowledge to gain deeper insights into complex subjects.

A time will however come (as I believe) when physiology will invade and destroy mathematical physics, as the latter has destroyed geometry.
My final word, before I'm done, Is "Cancer can be rather fun"- Provided one confronts the tumour with a sufficient sense of humour. I know that cancer often kills, But so do cars and sleeping pills; And it can hurt till one sweats, So can bad teeth and unpaid debts. A spot of laughter, I am sure, Often accelerates one's cure; So let us patients do our bit To help the surgeons make us fit.
My practise as a scientist is atheistic. That is to say, when I set up an experiment I assume that no god, angel, or devil is going to interfere with its course; and this assumption has been justified by such success as I have achieved in my professional career. I should therefore be intellectually dishonest if I were not also atheistic in the affairs of the world. And I should be a coward if I did not state my theoretical views in public.
It wasn't until I had performed by first autopsy that I realized that even the drabest human exteriors could contain the most beautiful viscera. After that, I would console myself for the plainness of my fellow bus-riders by dissecting them in my imagination.

If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide.
The primitive fight-or-flight regions of our mammalian brains react to immediate danger. We instinctively run from an avalanche but the gradual retreat of a glacier, the portent of the far greater danger of rising temperatures and rising oceans, just doesn't get through to us in the same way.
We must never make experiments to confirm our ideas, but simply to control them.
I'm a scientist, not a theologian. I don't know if there is a God or not. Religion requires certainty. Revere and respect Gaia. Have trust in Gaia. But not faith.

Darwin's theory of evolution is a framework by which we understand the diversity of life on Earth. But there is no equation sitting there in Darwin's 'Origin of Species' that you apply and say, 'What is this species going to look like in 100 years or 1,000 years?' Biology isn't there yet with that kind of predictive precision.
