An epistemology for jointly sufficient conditions involves the understanding of how knowledge is acquired through a combination of conditions that, when taken together, are sufficient to justify a belief. It focuses on the relationship between these conditions in establishing the reliability and validity of knowledge claims. This approach emphasizes the importance of considering all relevant factors to support the justification of knowledge.
