DESCARTES 2006 © Joost SWARTE. New Yorker cover art. 'The evil genius, sometimes translated as 'evil demon.' Concept in Cartesian philosophy. René Descartes hypothesized the existence of an evil demon "as clever & deceitful as he is powerful, who has directed his entire effort to misleading me." -wiki. Pretty deep philosophy that, eh? Or rampant paranoia. Hard to tell. Maybe time to stop overthinking & go for a nice walk :-) Descartes writing book surrounded by red devils. Great cartoon.
