Ongoing knowledge

Abstract

Ongoing knowledge is that knowledge that a person possesses continuously across a period of time. Given the plausible assumption that knowledge implies justification, it then follows that ongoing knowledge implies ongoing justification. However, the actual character of a person's justification for a belief often changes as time passes. Two types of changes in one's ongoing justification are explored: content change and structure change. It is argued that justification held over time often undergoes both content and structure change, and that the latter sort of change has interesting implications for theories of epistemic justification.
