Will and Cogito

'Cogito' derives from 'co-agitare', with 'agitare' meaning 'to set in motion'. But, setting oneself in motion is Motility, and Motility is Will. Thus, 'cogito ergo sum' , at bottom, means 'I will, therefore I am', with the standard 'I think' losing the dynamic connotation of 'I cogitate'.
