Although he assures himself of his own existence by his modes of thought, he remains uncertain of the reality of an external world. He doubts whether there is anything of material substance that provokes thought within h

Ideas come to be in dreams independent of external objects and perhaps this is true of ideas when we are awake. It seems that Descartes finds it necessary to first establish the existence of a non-deceiving God before he can be assured of the existence of anything beyond himself and his mode of thought.
