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
In the philosophic sense, observation shows and experiment teaches.
Interpretation
Observation and experimentation are crucial for gaining knowledge.
Claude Bernard highlights the importance of both observation and experimentation in the pursuit of knowledge. In philosophy and science, observation refers to the careful watching and noting of phenomena, while experimentation involves actively testing hypotheses to uncover truths. Together, they form the foundation of understanding the world around us.
In practice
During a lecture on the scientific method, this quote can be emphasized to illustrate the importance of empirical study.
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.
After the sale of Celtel, I really wanted to give the money back, and I had a number of choices - to go and buy masses of blankets and baby milk or to go into Darfur or Congo. That would have been very nice actually, but it's just like an aspirin: it doesn't deal with the problem.
The law must be stable, but it must not stand still.
Poets are always making waves. I mean, you know, in an ideal situation, the ideal republic can't tolerate poets because - it isn't that they mutter and criticize; it is that the poet does not accept the situation called the 'perfect' condition of man - in other words, perfect in the materialistic sense.
Men are more compassionate/(nobler)/magnanimous/generous than God; for men forgive their dead, but God does not.
Falsehood is never in words; it is in things.
And of course these days I feel like there is a nation of us - displaced southerners and children of the working class. We listen to Steve Earle, Mary J. Blige, and k.d. lang. We devour paperback novels and tell evil mean stories, value stubbornness above patience and a sense of humor more than a college education. We claim our heritage with a full appreciation of how often it has been disdained. And let me promise you, you do not want to make us angry.
