Plural of aporia; situations of logical difficulty or doubt; philosophical puzzles or paradoxes that seem impossible to resolve.
From Latin aporia, from Greek aporia meaning 'impassable' or 'without passage,' from a- (not) + poros (passage). The term moved from literal 'being stuck' to philosophical 'being stuck in reasoning.'
Zeno's famous paradox about Achilles and the tortoise is the ultimate aporia—it seems logically impossible for someone to catch up to something ahead of them, yet we know they can, which makes it a perfect philosophical puzzle.
