Hume was being mindful before mindfulness was cool. Indeed, as Western philosophers go, Hume was pretty Eastern. A number of his views align almost uncannily with Buddhist thought, including an argument he mounted against the existence of the self. Some scholars have suggested that this may be no coincidence, that he may have somehow encountered Buddhist ideas even though they had barely begun to drift westward from Asia. Certainly the idea that feelings run more of the show than we realize is Buddhist in spirit.
