Rabelais’s training as a doctor (completed in 1537) allowed him to make the connection between the body and the mind and promote a lifestyle (and style of education) that flew in the face of more traditional approaches to understanding the world.
This excerpt makes connections to Rabelais' medical background to his broader worldview, particularly in his commitment to some Renaissance humanist ideals. Through the emphasis of the link between physical & mental health, Rabelais distances himself from older & more rigid scholastic traditions that separated the body from general intellect. It's clear that his focus on education & physical vitality is present, and it reflects the Renaissance belief in human potential & balanced self-development. Rather than just simply relying on theological authority, Rabelais encourages observation, experience, & care of the WHOLE person.
