Summary
This quote is from Ludwig Wittgenstein's philosophical work, "On Certainty." It implies that if someone acknowledges the existence of their own hand, which is a perceptible and tangible object, they can be granted acceptance or agreement regarding all other claims or knowledge. In other words, it suggests that by recognizing the reality of something seemingly obvious and irrefutable, we lay the groundwork for accepting other truths or ideas. The quote highlights the significance of basic, concrete experiences in shaping our understanding of the world.
