The view that justification for knowledge never comes to an end—there are always further reasons, deeper grounds, more fundamental principles. You know something because of a reason, but what justifies that reason? Another reason. And so on, infinitely. Infinitism rejects the search for foundations (foundationalism) and the circularity of coherentism, embracing instead the infinite regress as the actual structure of knowledge. We don't need a stopping point—we need an infinite chain of reasons, and that's okay because we can always ask "why?" again and get a better answer.
"You keep asking 'how do you know?' and I keep answering, and you keep asking again. Epistemological Infinitism says: good! That's not a problem—that's the structure of knowledge. We don't need a final answer; we need an infinite chain of increasingly interesting justifications. Keep asking forever."
