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.

It is impossible to devise an experiment without a preconceived idea; devising an experiment, we said, is putting a question; we never conceive a question without an idea which invites an answer. I consider it, therefore, an absolute principle that experiments must always be devised in view of a preconceived idea, no matter if the idea be not very clear nor very well defined.
I try to show the public that chemistry, biology, physics, astrophysics is life. It is not some separate subject that you have to be pulled into a corner to be taught about.
When I meet God, I am going to ask him two questions: Why relativity ? And why turbulence ? I really believe he will have an answer for the first.
The constancy of the internal environment is the condition for free and independent life: the mechanism that makes it possible is that which assured the maintenance, with the internal environment, of all the conditions necessary for the life of the elements.
Every great advance in natural knowledge has involved the absolute rejection of authority.
