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
Those who do not know the torment of the unknown cannot have the joy of discovery.
Interpretation
One must experience hardship and uncertainty to truly appreciate the joy of finding new knowledge.
This quote by Claude Bernard implies that the challenges and fears associated with the unknown are essential for experiencing the profound joy that comes with discovery. It suggests that without confronting the discomfort of uncertainty, one cannot fully value the satisfaction that arises from uncovering new truths or ideas. The essence of learning and growth stems from navigating through the chaos and confusion that comes with exploration.
In practice
In a motivational speech about overcoming fears and embracing challenges.
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.
Despite the constant clamor for attention from the modern world, I do believe we need to procure a psychological space for ourselves. I apparently know some people who try to achieve this by logging off or going without their Twitter or Facebook for a limited period.
Fear is stupid. So are regrets.
The wisest of the wise may err.
Good advice is something a man gives when he is too old to set a bad example.
What should we think of someone who never admits error, never entertains doubt but adheres unflinchingly to the same ideas all his life, regardless of new evidence? Doubt and skepticism are signs of rationality. When we are too certain of our opinions, we run the risk of ignoring any evidence that conflicts with our views. It is doubt that shows we are still thinking, still willing to reexamine hardened beliefs when confronted with new facts and new evidence.
Keep silence for the most part, and speak only when you must, and then briefly.
