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
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.
Interpretation
What this quote means
Theories in science evolve and improve as more facts are discovered, akin to climbing a stairway that expands one's perspective.
Claude Bernard's quote suggests that scientific theories are not static but rather dynamic constructs that develop over time. As scientists gather more empirical evidence, these theories become more comprehensive and accurate, much like ascending a stairway that allows for a broader view of the surrounding landscape. This process highlights the importance of continuous exploration and understanding in the scientific endeavor.

All quotes βWhen 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.

Inventive genius requires pleasurable mental activity as a condition for its vigorous exercise. "Necessity is the mother of invention" is a silly proverb. "Necessity is the mother of futile dodges" is much closer to the truth. The basis of growth of modern invention is science, and science is almost wholly the outgrowth of pleasurable intellectual curiosity.
