Descartes, Rene - I think therefore I am

A description of the experience

Rene Descartes – Key Philosophical Writings

What of thinking?  I find here that thought is an attribute that belongs to me; it alone cannot be separated from me.  I am; I exist, that is certain.  But how often?  Just when I think? For it might possibly be the case if I ceased entirely to think, that I should likewise cease altogether to exist.  I do not now admit anything which is not necessarily true; to speak accurately I am not more than a thing which thinks, that is to say a mind or a soul, or an understanding, or a reason, which are terms whose significance was formerly unknown to me.  I am, however, a real thing and really exist, but what thing? 

I have answered -  a thing which thinks
