Primum Non Nocere

Entin Square is at the entrance gate to the Tel Aviv University campus in Ramat Aviv.

The square is studded with cobblestones with quotes, sayings, illustrations or formulas of the great scientists, thinkers and writers.

In the current plaque appears one of the principles of medical ethics: primum non nocara (Latin - first do no harm), that is, if the treatment you doctors are about to give could harm the patient, consider the feasibility of the treatment once more.
The principle is similar to one of the principles of the doctors’ oath (the Hippocratic Oath) - "I will protect the patients from injustice and never harm them", and it is attributed to the American doctor Worthington Hooker, who actually attributed the phrase to the French pathologist Auguste François Chomel

Three months later, the same square was photographed, during that action it was discovered that a number of pavements had been removed and other pavements had been placed in their place. In this tile the design is different, see the other tile Click for a larger image

(A line has been added to this tile to explain the saying:
one of the principles of medical ethics and the motto of the medical school)
