Self-reference occurs when a statement, concept, or set refers to itself. This idea is crucial in understanding paradoxes and logical constructs, particularly in relation to set-builder notation and the foundations of set theory. It can create situations that challenge the consistency of mathematical systems, such as those demonstrated in Russell's Paradox, where a set contains itself or refers back to itself in a way that leads to contradictions.
