The fact that knowledge endlessly recedes as the investigator is about to grasp it is what constitutes at the same time his torment and happiness.
Interpretation
What this quote means

This quote by Claude Bernard reflects the paradox of knowledge where the more one seeks to understand, the more elusive that understanding becomes. It captures the dual nature of intellectual pursuit, where the investigator experiences the agony of never fully grasping knowledge, while simultaneously finding joy in the relentless quest for learning and discovery.

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.
