"There is a wisdom in this beyond the rules of physic: a man's own observation what he finds good of and what he finds hurt of is the best physic to preserve health"

This quote by Francis Bacon is a pointer that we should trust our own judgement and intuition when it concerns our health. He is recommending that we should observe our own mind and bodies and remember of what makes us feel good and what makes us feel bad. This is the best way to preserve our health, as it is based upon our own specific experience. Bacon is recommending that there is a wisdom in this that exceeds the guidelines of conventional medicine. He is encouraging us to be conscious of our own bodies and to take responsibility for our own health. By listening to our own intuition and paying attention to our own requirements, we can make the best choices for our health.
