1,200 years before Descartes said his famous thing about "I think therefore I am," this guy, St. Augustine, sat down and wrote "Fallor ergo sum" -- "I err therefore I am."
1200 metų iki Dekartas pasakė žymią frazę: "Mąstau, vadinasi, esu", Šv. Augustinas atsisėdo ir užrašė "Fallor ergo sum" - "Klystu, vadinasi, esu".
