An old latin phrase,
literally translated as "Athanasius against the world". Athanasius of Alexandria (not to be confused with Athanasius Kircher) was a Christian Bishop in the 4th Century who defended Christianity, often supposed as using techniques compared to the modern
mafia, against the 'threat' of Arianism.
The phrase, "Athanasius contra mundum" can then be taken as an expression of the need to defend
one's ideas, no matter the cost.
