On Certainty

"On Certainty" is a philosophical work by Ludwig Wittgenstein that explores the nature of knowledge and what we can truly know. It questions the foundations of belief, emphasizing that certain things—like the existence of the external world or our own consciousness—are accepted as certain, not because they can be proven, but because they are part of the basic framework of understanding how we communicate and think. Essentially, it highlights that some certainties are fundamental to our ability to know anything at all, underpinning the way we interpret our experiences and the world.
