Solipsism

The doctrine that <B>I</B> alone exist.

The self can know only its feelings and changes.

There is only subjective reality.

Solipsism is of importance to philosophy and psychology.

Rene Descartes (1596-1650), the French mathematician, physicist and 'father of modern philosophy', made solipsism a central issue in philosophy.

Since solipsism has to do with how we learn and know, it concerns cognitive psychology.

The word 'solipsism' is a composite of the Latin 'solus' ('alone') and 'ipse' ('self') = the self alone.
