Lorraine Code's responsibilism is a unique contemporary theory of knowledge, aiming to clarify the nature and scope of knowledge from intellectual virtues or responsibility and community, which is different from traditional epistemic individualism and Quinean naturalism. However, limited to Code's own thought limitation, responsibilism didn't clearly defined epistemic responsibility, intellectual virtue and community and other core concepts, and due to the lack of rigid analyses and arguments, she cannot constitute a systematical theory of knowledge, make it more like a "slogan" doctrine. Nevertheless, responsibilism still brings abundant theoretical resources and has a far-reaching influence.
