Joseph Demarco (1718–1793) was a Maltese medical practitioner, a scientist, and a major philosopher. His areas of specialisation in philosophy were mostly philosophical psychology and physiology. Demarco's extensive interests make him quite unique. Indeed, though his main concern was human health, this must be understood in the widest of meanings. He was fascinated by the mechanisms of the human body but also with its infirmities, especially within their psychological and social contexts. This brought him to be very much attracted to the philosophical underpinnings of the human condition in all of its aspects. Both his life and his writings are proof enough of this.
