Abstract
This paper deals with psycho-physical dualism as developed by Nyaya-Vaisesika philosophers. It is argued that internal states like pleasure, desire, etc. that are directly observable only by one’s own self and not by others and thus are private are not bodily states that are directly observable by one’s own self and others and thus are public. Common experiences such as I am happy, I want this, etc. testify, in the absence of compelling evidence to the contrary, that desire, etc. belong to the self. The self is not only non-physical but also a permanent substance contrary to the Buddhist-Humean view that there are only fleeting internal states and no abiding self. Desire, etc. presuppose that the person who experienced something in the past remembers it now and desires it so that the agent of previous experience and later remembrance is the same continuant person.
