The Chinese concept emphasizes inclusivity and recognition of diversity within a category, while Popper's philosophy highlights the inherent difficulty in proving absolute truth and the central role of falsifiability in scientific reasoning. They operate in different contexts and address distinct aspects of thinking and epistemology.
The Chinese concept [白羊黑羊都是羊] reflects a pragmatic and inclusive perspective. It emphasizes the recognition that variations exist within a category, and it's characteristic of a broad, holistic view.
Karl Popper: underscores the challenges of proving absolute truth in scientific or philosophical contexts. Popper's philosophy of science focuses on falsifiability as a criterion for scientific theories. The emphasis here is on the inherent difficulty in establishing the absolute correctness of a theory, as opposed to the potential for demonstrating its falseness. E.g., In the context of your point, this reinforces the idea that while a theory may seem accurate based on available data (a million white sheep), the inability to exhaustively test all possibilities (the existence of a single black sheep) leaves room for potential falsification and challenges the absolute precision of the definition.
