Typically humans are characterized as having both a mind (nonphysical) and body/brain (physical). This is known as dualism. Dualism is the view that the mind and body both exist as separate entities. Descartes / Cartesian dualism argues that there is a two-way interaction between mental and physical substances.

Are the mind and body separate or connected?

Why the mind and body are not separate?
