Tout est poison, rien n'est poison, tout est une question de dose. Everything is poisonous, nothing is poisonous, it is all a matter of dose.
Claude BernardRead
We must alter theory to adapt it to nature, but not nature to adapt it to theory.β
Interpretation
Theories should be adjusted to reflect natural phenomena rather than forcing nature to fit our theories.
Claude Bernard emphasizes the importance of aligning scientific theories with the realities of nature. Instead of trying to reshape natural occurrences to fit pre-existing theories, we should develop our understanding of theories based on observations and facts derived from nature itself. This approach fosters a more accurate comprehension of the scientific world.
In practice
During a scientific conference discussing the latest research findings.
Tout est poison, rien n'est poison, tout est une question de dose. Everything is poisonous, nothing is poisonous, it is all a matter of dose.
When a physician is called to a patient, he should decide on the diagnosis, then the prognosis, and then the treatment. ... Physicians must know the evolution of the disease, its duration and gravity in order to predict its course and outcome. Here statistics intervene to guide physicians, by teaching them the proportion of mortal cases, and if observation has also shown that the successful and unsuccessful cases can be recognized by certain signs, then the prognosis is more certain.
The goal of scientific physicians in their own science ... is to reduce the indeterminate. Statistics therefore apply only to cases in which the cause of the facts observed is still indeterminate.
Theories are like a stairway; by climbing, science widens its horizon more and more, because theories embody and necessarily include proportionately more facts as they advance.
True science teaches us to doubt and, in ignorance, to refrain.
Now, a living organism is nothing but a wonderful machine endowed with the most marvellous properties and set going by means of the most complex and delicate mechanism.
Sci-fi has never really been my bag. But I do believe in a lot of weird things these days, such as synchronicity. Quantum physics suggests it's possible, so why not?
We've learned that musical ability is actually not one ability but a set of abilities, a dozen or more. Through brain damage, you can lose one component and not necessarily lose the others. You can lose rhythm and retain pitch, for example, that kind of thing.
The goal is to learn more about telomere length and other markers of ageing, how best to measure these markers, how they are related to health and lifestyle, and how people respond to learning their own telomere length results.
I had as much time to prepare for that moon landing as NASA did, and I still was speechless when it happened. It just was so awe-inspiring to actually be able to see the thing through the television that was a miracle in itself.
I hate crowds and making speeches. I hate facing cameras and having to answer to a crossfire of questions. Why popular fancy should seize upon me, a scientist, dealing in abstract things and happy if left alone, is a manifestation of mass psychology that is beyond me.
That is the essence of science: ask an impertinent question, and you are on the way to a pertinent answer.
