The mind-body problem is an old problem in philosophy that has raised several questions and possible solutions. This problem has permeated the major branches of philosophy, as it has strong ontological and epistemological implications. One cannot talk about this problem without committing oneself to a specific ontology or having an epistemological stance. This paper will focus on finding out what these ontological and epistemological implications are throughout the history of philosophy. On the other hand, the definitions of the word "mind" in antiquity will be sought in order to determine where the problem begins.
