> Fallibilism is the philosophical principle that propositions can be accepted even though they cannot be conclusively proven or justified[^1] Fallibilism states that any belief or claim can turn out to be false. No matter how certain you may be, your belief will always be fallible. For example you may say see rain falling outside the window, but there are so many parts of your cognition that remain fallible: - The window is actually a screen displaying rain - Someone is using a fake rain machine outside - You are dreaming - You're in a matrix-like chamber and the life you think you have is fully simulated It is impossible to know anything with certainty. In order to not question everything, we can acknowledge that all is fallible, and build knowledge on that principle. Fallibilism acknowledges that some things are more certain than others, and in contexts where propositions are near-certain, it is usually more pragmatic to treat them as certain. Some philosophers state that "*I think, therefore I am*" or simply "*I exist*" are some of the only infallible beliefs to exist, though this is not widely agreed upon.
